308 norma mag

It's a good round, with only slightly less power than the 300 WinMag with heavy for caliber bullets. It's an almost duplicate of the 30-338 wildcat, Winchester "out-marketed" Norma when these two rounds were introduced.
 
I shot one for years. I built it for elk and deer here in Idaho. Winchester had not introduced the 300 Win mag and I simply couldn't afford a Weatherby or a Winchester 300 H&H mag to blow out to something like the 300 ICL Grizzly at the time. This is a great cartridge, but doesn't do anything a 300 Win magdoes. If I were looking at a 300 mag today I'd either buy a 300 Win mag or the new 300 Rem Ultra-mag which outperforms both the 308 Norma or the 300 Win mag.

The 300 Win mag is a ballistic twin of the 308 Norma. I was getting 3150 fps from a 180 grain Nosler behind a healthy dose of 4831. This rifle killed a pile of elk and deer and I eventually gave this gun to my Nieces husband for a wedding present. He killed more elk and deer with it and now has retired to Alaska and is killing stuff up there with it.

With the ability to push a 180 grain bullet at over 3300 fps the 300 Rem UltraMag handily outperforms it with no more felt recoil that I could tell. Presently I'm shooting a Rem 8mm mag pushing 220 grain Sierra spitzer boattails at 3080 fps. I do like that 8 mag round better than the 308 Norma.

My 2 cents.

I shot a 8mm Rem Mag from the year it came out until the mid 90's and took many large animals with it. It was my primary mountain
rifle and it never failed me. My best loads were with the 200 nosler when it came out but I always wanted a good 220gr. In my hands, all the cup and core 220's failed to penetrate at short range. That left the Swift which did penetrate but the accuracy was not there. Glad the Sierra is working well for you.
The 8mm Rem Mag is best with the 220 driven to the velocity you are getting.

I have a couple of them and they both shoot. I was brought to the cartridge by the guy I learned how to build rifles from. He was a long time gunsmith who built and shot BR rifles for 40+ years.

He preferred the norma over the 300 WM because It has longer necks and the better brass at the time.

72.5gr 4831sc with either 168 MK's or 168 TSX's touching are a winning combo in just about every norma I've shot. It would almost always keep 5 shots at or under 1/2" @ 100 with the rifles we built.

I've owned a few 300WM's but prefer the longer necks of the norma with the brass of today making just about everything else equal.

As someone else has mentioned, Norma could not compete with Winchester's PR. Everything else equal, a .308 Norma will do anything a .300 WM will do with the advantage of a long neck. It was quite popular in Western Canada when it first came out. The Browning bolt action was a real shooter.

I like mine. I had it built a long time ago. I only ever hunted deer with it but it always shot well. I've never compared it side by side over a chrony, but I've been told (by guys that had them years ago when mine was built) that it has a slight ballistic advantage over a 300 WM. I don't know if it's true or what that logic was based on but if it isn't correct, I doubt it gives much up to a WM.
