7mm-08 specific question - hunting related

Post by Cal-ApeR » 14 Aug 2019, 2:07 pm

So, I am very very close to adding a 7mm-08 to my collection. They're a few reasons for going the 7mm rather than another 6.5 (which I may end up doing). Firstly and probably the biggest reason is brass. I know I will always be able to resize some 308 brass which isn't going where soon. This fits in nicely to my 243,260,308 and 338fed theme nicely.

Secondly, there are wide range of bullets, I guess mostly thanks to the Rem mag. However, this also leads me to problem. On yank forums, I've cover across a few people saying they had trouble incidents of bullets not expanding at close, medium and far ranges. Each think that perhaps manufacturers have made the 7mm bullets more specifically for the magnum and expansion for higher velocities versus the slower speeds of the '08. I think there is merit in their experiences as no manufacturer would like news spread that their bullets explode on impact. (the opposite with lack of expansion could be said too I guess).

This rifle would only be for hunting. Pigs, deer and goats. Not target shooting.

Can shooters of this cartridge give advice/experience on this questions. ADDITIONALLY, if anyone has reason to move be away from this purchase for other reasons, please let me know.

I could really go either 7mm-08, 270 (so similar ballistically) or the 6.5 creed/Swede. I have experience with all but the 7mm-08. It should be obvious now I'm just spending my tax return on toys, not needs.

I’ve read up on Nathan fosters website on 8x57 recently, and some 8mm bullets are designed for 8 mm rem mag and don’t perform in the 8x57 . Which would be the case in 7mm exactly like you said. Get onto stix as he’s played with 7-08 and if I recall correctly his rifle didn’t like some projectile weights. I’d PM him to see what he reckons. I don’t think you would be on a bad thing if you went to a 270 Winchester, but have a look at 280 rem . It’s a 7-06 and would have a bigger range of projectile than 270 . Just a thought . Cheers

I have a 7mm Rem Mag Sendero and reload for it.I use 100gn Sierra Gamekings for walking around hunting and 168gn Matchkings for the range I also have a heap of big game rounds from what I can see the 7/08 is 400 fps slower with the same bullet range.It is used in the south of England for deer hunting as the game is Fallow and roe deer.I would be inclined to use bullet weights between 120gn and 150gn for hunting and I totally get the one case for every thing mentality.How do you choose what to take I have a hard time with only 3 rifles

Thanks Gents. Thought I would check popular chamberings by sales in US for last year.

Creedmoor smashed it out of the park. Surprised 223 didn't come up on their radars. Needless to say there was nothing for the 7mm-08. Didn't really shock me though.

My experience is similar to what you worry about...although thats nothing to worry about...lol...

Though i dont shoot pigs--none here that i have access to--i just try shoot goats if i get the opportunity & i very occasionally hunt the odd herd of paper-skinned coreflute with it in a particular paddock out to 400 yds...

I basicslly found similar weight bullets in different brands were designed differently...

For example, the 7mm Nos BT from memory is supposedly a shift up designed for heavier animals (heavoer base/maybe thicker jacket i guess :unknown: ) where as the 120 Vmax was still a varmint type with rapid explosive expansion still at slower speeds.. . (Better for soft little goatoids)

Best results i got on goats were with 120 Vmax...
Although the 140 weight is toated as the "alrounder", i prefer those 120 vmax for goats...every goat ive ever hot with them has fallen over immediately--ive never had a run-on with them.

The latest im trying is speer 110 hp's that seem ok, but ive only head shot in close proximity so cant realy say how they perform until i hit a few in the chest at decent range...

I found the sierra 120 GK very explosive on skulls (head shots) under 80 yds (no head left lol) but i found they pencilled through their little ribs & soft chest cavities...
Having said that, i know of a bloke who (apparently) shot squillions of goats with this bullet & loved them...!!...but he was slso driving them faster than i was.

Ive only found loads for my 7-08 either down very low or right up high (100%-compressed loads) so i choose the low end as the other were very loud & really hammered the brass to the point of having to FL size every firing...bugger that...!!...

There is a projectile for every need in the 7mm range--you just need to find one that performs well for all your game choices, based on the speed you're sending them at....but that is the case with every cartridge when hunting...

There's many people with so much more experience than me with 7-08...hopefully you'll hear from them...

I like it...& i doubt you'll be disappointed...!!

Just one thing to be aware of...!!
If you're going to get your cartridges mixed up & put in wrong rifle on the bench...make sure you put a 243 in the 7-08...not the other way around...lol..

One thing ive learned using 308 cases in my 7-08...depending how tight the chamber is & how thick the brass is, you may have to turn some necks...
So make sure you measure the necks of loaded rounds & the fired cases, along with a bullet slip test in a few fired necks of any batch...
Or you may chase your tail & scratch big holes in your head wondering why a bullet that grouped beautifully with one batch of brass, sprays like a hand full of rocks with another batch...(meaning it could get dangerous with pressures if the brass is too thick)

I don't have a 7mm08 but shoot a 7mmBR which is even slower. If I want a frangable bullet that is very fast and explosive I use the 110 grain Speer TNT. It is accurate and expands well even on rabbits and foxes. I have used them on goats and medium sized pigs. I have also used Nosler BT and like Stix said they are excellent.

Thanks Stix and SCJ. It leaves me a lot to think about. I do wonder if the 270 would be easier all round to get brass and projectiles but I do have a feeling it will be harder to get in the coming years. Seems like the creedmoor is killing a few old favorites slowly. I really don't mind the 270 and the long action isn't something to turn me off but i definitely like the idea of future proofing myself with the ability to resize 308 brass. Not sure the 270 will be as popular in another 20 years.... On another note there are a few creedmoors going cheap. Don't know if I can do it though.

270 will be around if thats what you like my nephew has a 7mm08 and has taken a few whitetail deer with it and has done good.
keep in mind many of the loads will be about the same as the 7x57 my nephew is loading 139grain hornadys in his 7mm08

The 270 is a great old case which is flat shooting and hard hitting but not a giant leap above a 7mm08. The 270 caliber and like the 257 it is not popular and you have less of a choice of projectiles. If you are hunting things that you don't think the 7mm is suitable for then you would be better off stepping up to a 300 WSM or a bigger magnum like Weatherby, RUM or Winchester.

I would be confident using a 7mm08 at reasonable ranges for all but the biggest deer or pigs. After that you might be better off with a 416 Ruger or similar. Just my 2 bob.

Mmm, personnally, i dont think u need one. I would just use the 308 or 243. IMO. :roll:

If you already have a 260 and a 308 - isn’t adding a 270 little.... trivial?

Yep you're right. I have a toy spending problem. I really don't need anything. I do have things covered. I'll also inherit a few different calibres in years to come. A few lovely sakos. In the meantime I guess I'm look for good calibres in beat around hunting rifles liked the howa etc. Probably not looking for a magnum, I do enjoy plinking sometimes so that would be out of the question.

Point taken on 270 with limited bullet selection.

Still keen to hear more experiences with expansion etc in 7mm projectiles.

I wouldn’t worry about “old favourites “ becoming obsolete. So long as you have the common 308/30-06 bolt face you can always rebarrel. If I had to pick a 7mm it would be a 7x57 or 280 rem ( 7mm -06 ) people keep saying 222 is dying but more people are getting back into it ( like 22 hornet) cause it is a great naturally accurate caliber. The yanks keep reinventing old calibers into new to stimulate new firearms sales, but the old classics that do the job keep on keeping on . And you can always rebarrel

The 270 has lasted 95 years, I am sure you will see it around for the next 20 or 30 years you may be hunting with it.

The 7mm will do anything that a 308 can do with similarly constructed bullets. What you really need is something different, Grendel? 45/70?

Mate...buy the 7-08... :thumbsup:
Then try get on to the bullet manufacturors for detsils of the construction of various bullets...that will give you a starting point of which bullets to try...
As i said, i got on to Nosler direct & they were happy to tell me that their 120BT was at a point of heavier construction than the calibre's under it, & that i may be better suited to a more franjiable bullet for thin skinned & light bodied snimals such as goats...especially given i wasnt driving them particularly fast.

They may slso be sble to give you details of fragmenting/mushrooming at various velocities too...
But as i said, you wont know until you buy a rifle & see what it likes to eat...
In other words, someone msy tell you brand "X" bullet in their hollow point is criptonite for deer & pigs, but if it dont shoot in your rifle, you need to find a diffetent bullet....of which there is plenty of choice in 7mm...

If you're worried about bullets not opening up cos they designed for magnums, thats just a velocity thing...choose lighter constructed bullets that open when moving slower... :thumbsup:

You wont be unhappy with a 7mm, & if you like short action like your 243, there's your answer...

Not trying to shut down any further info, or your search for it, just trying to help...

Have you bought it yet...?...lol

You could be suffering what is called a "buyers objection"...meaning youre after confirmation from others by way of objecting to the obvious choice... :lol:

If you got the coin, go get it--you'll love it... :thumbsup:

BTW i know someone with a 270-08...yep...a 308 necked down to 270...
They wanted a 270 in short action & decided to get that chambering... :unknown:

Why not type up what you actually have (inc scope and prime reason for the rifle - hunting, target, etc) - then we can all have our say on possible “toys”...

Gday, Cal-ApeR

RE: Your 7MM-08 Issue,

Sounds like the early days of the.444 Marlin, Calibre projectiles.

Except in reverse order, so yes their is a precedent to this type of issue.

If I have this right,

in order to save money people were.

Reloading .444 Marlin using .429, .44 Cal pistol projectiles to reload in .444 the problem was pistol bullets were now being used in a rifle and driven.
At about 2200-2400 FPS.

Way above pistol velocity's in those days and the result was pistol projectiles rapidly expanding on blades of grass or just self destructing on the animals hide. Little too no penetration being achieved. However, proper .444 ammunition is a real brush cutting cartridge,

The issue was eventually resolved by projectile manufacturers, producing for the reloading community a number of various weight .430 Rifle projectiles.
Specified for use in rifles of this calibre.

However this issue would have definitely cost them some sales in the early years.

My question for you to consider is this!

Apart from your mentioned, brass considerations in respect to the .308.

The tried and true 7X57mm case has more powder capacity for reloading than the 7mm-08.

In addition as the 7X57mm Case is longer than 7mm-08.

This tends to eliminate most bullet, depth seating, verses powder increase issues that may arise with 7mm-08.

7X57mm can be safely loaded hotter than 7mm-08, if required.

Will give good results for projectiles weights ranging from about 140 grain standard to175 grain.

Which Hypothetically! would take elephants,

Just as effectively now as it did in the 1930's-40's.

In Fact, probably better because modern powders.

are just so good now.

Anyway points for consideration, its still your call!

GunBlu490 on YouTube has a very good article on this.

When he talks about Parent Cases of our modern .308 and 270.

Kind Regards

"Point taken on 270 with limited bullet selection."

rubbish, the 270 is a true 7mm caliber and has plenty of very good bullets out there, for crying out loud you only need one :lol:
nosler sells from 100gr to 160gr bullets including partitions
berger sell from 130gr up to the eol 170gr elite hunter with a bc of .662 perfect long range bullet that is made for hunting
sierra sells 115gr to 150gr including smk's
hornady sell 100gr to the 150gr sst's I shoot and have a .525 bc, they are rated for medium to large game from 50lbs to 1500lbs

I recon you should be looking at the 270wsm for shooting 150gr bullets very flat and very far
my 270wsm shoots the 150gr sst's one hole at 200yds and 3220fps, whooooompa
it is a bit flatter shooting than my 6.5x284 with 142gr smk's .535 bc at 2950fps
and its on par with my 22 dasher shooting 55gr zmax at 3800fps with both dialed in for a 200yd zero they hit bull again at 450yds

the 270 is under rated by people who are blinded by bullchit :lol: dont underestimate the 270 cal :drinks:
