300 Norma, 300 RUM, 300 win, 300 WSM

[flutch]

I know the 300 win is a step up in terms of case capacity, etc - just wondering if it’s a far enough step up and over of the 30-06 I already own...from what I’ve read, the WM iS approx 250fps better than the 06 for same weight projectile which equates to an extra 100 yards or so of useable range. Not really a huge leap forward...
Hmmmm decisions...decisions.

Where the 300win shines over both the WSM and the 06 is larger projies and reach, that extra powder capacity does a lot to really shove those bigger projies along for further in the supersonic range. And you do notice the extra oomf in regards to other "deer" cartridges, I have a 270 that is pretty damn flat shooting with 130gn projies pushing over 3100fps but the 300win shooting 150gn projies at 3200+fps is something I had to get used to, so flat it's almost confusing at first. But then you can still push large projies over 2850fps giving a really nice dope for long distance stuff, whereas the WSM and 30-06 would be closer to 2400fps and 2600fps being optimistic, with stability issues no doubt as they end up transonic sooner.

Have you considered 300 PRC? It's basically a new and improved 300 Win Mag: no belt, 30 degree shoulder, slightly more powder capacity.

I love how the article states that the 300 Norma is a necked down 338 Lapua. Silly me for thinking that Lapua would call it the 300 Lapua. I wonder what Norma would call the 338 Norma case.

I think the 300 Norma is a necked down 338 Norma. The 338 Norma was based an a wildcat cartridge: the 338 Lapua shortened to fit in a remington long action. Norma adopted it and called it the 338 Norma. So basically the 300 Norma is a shortened, necked down 338 LM.

Thanks Nigel, I do know a little about the round. If you neck down a 416 Rigby to 338, you don't end up with a 338 Lapua or Norma. When you neck down 338 Lapua brass, what do you end up with?

[TassieTiger]

Just had a look at the prc - specs look great. Not sure on brass or platforms but ballistics are between 338 lap and 300 Norma...with less recoil of either.
So many options...gets a bit confusing - especially when you don’t 100-% know the exact reason behind building it other than having a boomer.

The 300 Norma should have a lot more grunt than 300 PRC. Based on measurements I've seen online the powder chamber volumes (case volume less neck volume in grains of water) are as follows:

300 Win Mag: 85gn
300 PRC: 89gn
300 Norma Mag: 97gn

I would expect 300 Norma to be a bit of a barrel burner.

stuff it taz , just get something in 50 BMG

heres a fun gun for you Tassie

[TassieTiger]

My missus was just looking over my shoulder and asked me what I was doing....I said I’m just getting some help with my next next little .22 project.,,then she started reading...”who’s big rich, who’s marksman, wtf are they telling you to buy? And WTF IS THAT! No Effing way is that coming here...that’s bull, no way, tell those guys to bugger off, we have kids here, nope, not happening, who do you think you are Rambo!”

I’m still rolling on the floor laughing.

[Stoney]

Whatever happened to the WSSM guns? Advertising hype?

[TassieTiger]

Don’t think there’s anything wrong with the WSM - just the ballistics fall off a little compared to the other big 3’s.

416 rigby...375 ruger...338....300wm - there’s too many to consider...

I’m talking about a rifle that your almost not wanting to shoot but love it regardless it...maybe gets 50 shots a year. Something you can hand to a friend at the range and when he pulls the trigger - he can only mutter the words wow. The one shot you do fire hunting, echoes up the valley for 11 seconds...the rifle you pull out to have a shot at the 800 yard plate - and it busts through the plate...that kinda thing lol

[marksman]

not the first time I've been told to bugger off Tassie

but the trick is you have to be persistent and tell her how much this gun would make you happy and that you will hand it down to the kids

what I thought of with the howa 375 ruger case was to wildcat it to a 30 cal , the 30-375
Here's a picture of a 375 Ruger (260 Accubond), 338/375 (250 Matchking), 30/375 (185 Berger VLD), and a 300 WSM(180 SP) that you might find interesting.



nothing wrong with dreaming a little

[TassieTiger]

Anyone of those BIG ones WILL DO LOL.
I don’t have the experience to mess around with wild cat reloading or matching barrels etc - I’m more enthusiastic than experience at the moment lol. I’d love to do a 375 or something left of field but...I guess I don’t have to rush.

And I think that my lack of experience is going to become a deciding factor - the 300 prc looks great but rifles and brass not easy to come by. The 300 Norma and rum are on the edge of “screw it - buy a 338 lapua”...but the 338 lap then calls into question extremely expensive consumables...the 300win is a lot more mainstream, is from what I can see, a definite leap over the 06 caliber I have, can be managed without a brake, is relatively cheaper for consumables...but - it is then “only” a 300 win lol....

[Sergeant Hartman]

Mate tbh as I said first time 338 lapua it is. Unless toy Wanna crazy than 50bmg will suit you best... get a second hand sometimes you get lucky and get consumables with it.

Or 375h&h not a brash idea... maybe a Ruger1 in 375h&h

[flutch]

If you're looking to go ker-bang get a 378 weatherby heh, or a 338 rum might go nicely too

The 378 Wea Mag is a romping stomping case, Roy Weatherby's favourite. I shot out the barrel on mine and it beat the hell out of me. Not many people took me up on a try of that beastie. I prefer shooting both the 416 or 460 Weatherby. But for longer range knock down power the 378 is hard to beat. Beautiful looking cases with double radius shoulders.

In regards to the Mrs, if you have to explain it, she was never going to understand. Show her the YouTube footage of a 10 year old girl shooting a 505 Gibbs. My little girl has shot my 416, who says big bores cannot be family entertainment.

[TassieTiger]

^^^ a 10 year old girl shot a fukn way lol
She might be fine now, but in 5 years time she’ll develop a twitch lol.

How is barrel life in these cannons? I’ve already described what I’ll be using for, so don’t need F class accuracy...
378 weatherby- getting a little crazy now lol

300PRC

[SCJ429]

My 378 had shot nearly 3000 rounds and was still shooting OK but I hated the light #3 profile factory barrel. I personally think it needs the same profile barrel as the 460 and a different stock. The standard walnut Monte Carlo stock does it no favours and I swapped it for an aftermarket laminated straight comb stock.

The rifle is now a 300/378 and I expect to get about 1,200 rounds through it before it goes off. Next barrel I am thinking of a 300 Lapua Inproved or a 375 Lapua.

The 460 should have good barrel life, probably 3,000 to 4,000 rounds. I don't expect to burn it out.

My personal opinion for you is a CZ 550 chambered in 416 or 450 Rigby. Very plesent to shoot and a classic looking rifle in the Rigby tradition. It will make your 30/06 feel like a pussy cat. The Mrs might even want to try it out.

[TassieTiger]

Haha...my missus won’t touch the 260. The 223 and .22 - yes...that’s it.
My 06 is surprisingly bothersome. Weighing 3.2kg with scope - on the bench it cracks hard with 180’s.
I imagine any of the 300’s will add 20-30% to that and the shoulder busters your talking about - probably double the 06 lol.
I think you might n looking for an organ donor making recommendations like that lol

[marksman]

get a 375 H&H and ream it out to 375 weatherby, 300 fps better than the 375 H&H and just shoot the 375 H&H cases in the 375 weatherby to form

have been kicking the idea around for for mine for a hell of a long time but problem is that BOB from KUDU has shut shop at the moment ill and he is the only smith I know of that has the reamer

[SCJ429]

Detached retinas can be fixed, I am with Marksman. I don't think you need any more speed in a 30 cal but a 375 can deliver a heavy payload. I shot a 375 Ruger and it was a pussy cat. The 375 Weatherby is a handy thing too, you can load them down so they have no sting or run them fast for a bit of fun.

[SCJ429]

Pity you are not on the mainland, come to the range with me and I guarantee you will go home with a smile and a Weatherby eyebrow.

YO ! Grumble mumble big efen power mumble kaboom mumble taz.

Interpretation of Rambo language- hello, I believe you require a large caliber firearm taz .

[juano86]

No mention of the 30 Nosler or even 33 Nosler? sounds like it would suit your intended purposes with little fuss as you can use a win mag action. Brass will be around for a long time as many factory rifles and ammo available for 26 / 28 Nosler. The ballistics aren't too shabby either. Interesting article: https://gununiversity.com/300-norma-mag ... 30-nosler/
Iv been thinking of a 30 Nosler, or as mentioned above, wildcatting the 375 Ruger cartridge to either 338-375 or 30-375.

[SCJ429]

Isn't the Nosler just a shorter RUM. What can it do that the Ultra Magnum cannot do?

[TassieTiger]

Thoughts?
