Strictly for hunting or serious LR shooting... 300 WM every time.

Hunting... The huge array of available, economical projectiles, cases, and just the fact that the .30 is more flexible when/if you want to step up to very heavy big game bullets.
Long range precision... Sako TRG 42's don't come in 7mm Rem so i didn't have to ignore that calibre yet gain. And a big thing, where I am and the shops I can get to, 7mm projectile and cases range is limited.

Sure, the numbers touted say the 7mmRM has the edge in drop because for weight the projectiles are smaller diameter so can achieve higher BC, but to solve that in the TRG I use 240 and 250gn Matchkings. I bet apart from a few elevation clicks, there is no benefit to 7mm.

As far as any edge in game goes, there isn't any - exception being big bullets for big animals is better in .30, if you ever get that opportunity.
I think .300WM is that much better for hunting, I have two Sako sporters, and for hilltop to hilltop, another 27" barrel TRG42. All in .300WM.
And just for insanity, I have a lightweight 300RUM too, .30 is so impressive.

There will be plenty who say "but what about the numbers!!!", but I say, come and show my why your 7mm is superior out here across the paddock.
Competition? I have no idea, not the slightest bit interested.

yeah , i'd considered a 7mm rem mag myself . bit less recoil , good ballistics with lighter bullets . would more than do the job . but it won't do anything i can do with a 30-06 at reasonable ranges . what's that old saying "7mm rem mag , flat as a 270, hit's like a 30-06" :D

i had a play with a tikka t3 in 300mag one time , can't say i liked it . i think if i had to choose i'd take the 7mm . less recoil means it can be a lighter carry rifle , that's probably easier to shoot . guess it comes down to intended game as to which one is suitable . cr@p , you've put a idea in my head ! i've got the itch for a new purchase .... :roll: :D

JMHO :thumbsup:

I chose the 300 because I like .308.
It truly is gods calibre.
I have a 30/30 as well.
I'd like all the 30's if I could.

The pills are plentiful. Every gunshop I visit carries a good range of 30cal.
If one shop doesn't have my lollies, I can normally find them at the others I frequent.
Huge selection of factory rounds if you're not reloading too.

My hunting partner chose the 7RM.
For us, there is no difference in either of them for what we both do.
His shoots much flatter than mine does, but I'm throwing a heavier pill.
He doesn't make a scope adjustment out to 200yds. The point blank zero on them 7rm's is something else.
I'm am throwing a180gr Sierra SPBT, and he's throwing the 165gr tipped game king.

They both kick. Yes, that's a magnum thing. His was a lot worse than mine because he has the lite version and mine is a varmint, but fit a muzzle brake and it calms them right down.

It's the debate that will go into the next millennium, but I say they are both awesome cartridges and they are bloody effective at what they do.
I would purchase either.
I have been thinking about a 7rm, but I have a 308 project to finish first.

Why?
Is it nostalgia?

30-06 just gets the job done at typical hunting distances with easy to obtain projectiles , powder , cases and primers . big range of projectile weights 110-220gn that work , but soft 165gn boat tail speers would be my choice as a do all load on the central east coast of australia . saw a fella in NT using 180 barnes on scrub bulls, was going for heart shots, and penetrated through 3 pigs in a mob, the first one being a very big sow . 30-06 is a very flexible cartridge . with reasonable recoil in a hunting weight rifle . 308 is at it's best with 150's , 30-06 surpasses this with 165's . bigger boiler room , more oomph

for the game that i hunt 270, 308, 30-06 are all up to the task , with a suitable bullet range to suit the medium game i encounter , with 30-06 having the ability of more flexibility to shoot heavier projectiles well should the need arise .

back on topic , the main reason i went with 7mm rem mag is the same reason i advocate for the 30-06 . bullet weights suit the game i hunt and flexibility in bullet choice. more bullet choice in 30 cal for sure , but there's more than enough 7mm bullets for any job at hand . 7mm has tolerable recoil in a hunting weight rifle, 300 mag goes up a bit in recoil level over the 7mm . it's horses for courses i guess . with correct projectiles for the job at hand there's no bad choice , it's more the application of the chosen rifle with regards to abilities and limitations . real long range shooting with plenty energy , go the win mag with eldx's for good results i guess . pigs, deer , goats out further than a 270 go the 7mm mag. any shot over 200 meters i get more selective, so i don't really need a calibre with more reach than a 308 with a 150 . 30-06 with a 165 gives a bit more authority than the 308 but :D

ADI load 223, 243 and 308 , boring as bat sh!t , but sane , practical rounds that get the job done for the majority of users . we all like something different and special to play with but :D wouldn't be interesting if we stuck to the sane , practical choices . which all boiled down, it's personal choice for personal reasons .
probably doesn't help the OP make a choice , be realistic in what your rifle is going to be used for and choose appropriately i guess :thumbsup:

You have described exactly my argument for the 300WM.
You are just being nostalgic. :sarcasm:

300Win Mag has a lot of blast. I shot a sambar at 200m that bolted after being hit by a 300. I pulled both bullets out. 180 oryx for the300 and 220 grain woodleigh from my 3006 . Penetration was the same.

Maybe we should arrange a friendly competition!
Straight out of the gun bag, patch-out and balloons out!
Ranges and target sizes pulled from a hat so there's no favourites :thumbsup:
