30-338 winchester magnum

I WAS WONDERING WHAT PEOPLE THOUGHT OF THIS ROUND. I RECENTLY BOUGHT A REM 700 MAGNUM ACTION AND HAVE A HEAVY 28.5" KRIEGER 30 CAL BARREL 1 IN 11 TWIST. IM THINKING OF GOING WITH THIS ROUND AND WILL SHOOT 175-190 GRAIN BULLETS. I DONT REALLY NEED ANYTHING BIGGER AS I HAVE A 338 EDGE. THANKS FOR ANY INFO OR OPINIONS.

Re: 30-338 winchester magnum

I have shot one and worked up loads for it. It got popular 20-25 years back when some guys won a few 1000 yard matches with it. It went away about as fast as it arrived on the scene. It was known for accuracy with velocities about that of a 300 wsm. The 300 wsm is a better cartridge. The 30-338 win mag is basically a 308 Norma magnum. I think they are virtually the same thing.

Re: 30-338 winchester magnum

THANKS FOR THE INFO. I AM LEANING NOW TOWARDS THE 308 NORMA MAGNUM AFTER READING MORE ABOUT IT. AFTER ALL THEY ARE BASICALLY THE SAME ROUND AND I CAN USE 7MM REM MAG AND 338 WIN MAG BRASS OR THE NORMA BRASS. DO YOU KNOW OF A 30 CAL. BELTLESS ROUND THAT WOULD BE A BETTER OPTION IN THE MAGNUM LONG ACTION. I REALLY DONT WANT TO GO ANY BIGGER THAN THIS ROUND. THANKS.

I have owned, shot matches and hunted with one and it is a very good round.

The 30/338 was one of the best 1,000 yard rifles and set many records.

My pet load for 1000 yard matches was 190gr MKs at 3091 ft/sec in a 27" hart
1 in 10 twist. My hunting load was a 200gr Nosler Partition @ 3018 ft/sec.

The 308 Norma is ballistically the same but brass is slightly different and one should not be
fired in the other.

Ether one will shoot very good and IMO will out perform the 300 WSM with the heavy bullets
because of case capacity, and the new powders should boost the velocity even higher with standard chamber pressures 55,000 instead of 65,000 like the new short mags.

The next step up in a none belted case would be the 300 RUM but you said you didn't
want anything that large.

I shot one for a number of years and loved it. I'd rather shoot it than the 300WBY I now have. Uses inexpensive , easy to find brass and is easy on powder. A favorite load of 65gr imr 4350 would push a 180 smk. 3040. in a 26" barrel. I never shot it past 750 yds. but at that distance a gallon milk jug was a easy shot. I don't think today that I would go out of my way to have one built unless I had an action that was already made for that size case. Mine was built on a P17 Enfield and it had the magazine length to seat the bullet out as far as ought to be.

Re: 30-338 winchester magnum

JEcustom, With the new powders available today the 30-338 winny and the 308 norma may get more velocity with the heavier bullets. I was comparing what me and others are getting out of the 300 wsm now with what I was able to do with the same 26" barrel length in the 308 norma and 30-338 win mag 20-25 years ago. About the same velocities with bullets up to 200 grains in a more compact case that is just as accurate as the 30-338. With longer barrel lengths that would allow more burn out of a bigger dose of slow burning powder I can see where the 30-338 and 308 norma could get an advantage with the heavier bullets, particularly with some of the newer slow burn rates out there. I haven't tried a 300wsm, 308 norma or 30-338 with a barrel longer than 26" so I would not know.

Some guys are getting right at 300 win mag velocities out of the 300 wsm which is a bigger case than the 308 norma or 30-338 win mag. With a 25" barrel in 300 wsm I am getting well over 3400 fps with the 150 grain, over 3100 fps with the 180 and over 2900 fps with the 200. I would never have believed that just looking at the little short mag case but after shooting the daylights out of a couple of them I am a believer now in the short mag. They allow you to use a faster powder which gets top velocity in the shorter, lighter barrels.

I appreciate your opinions on here and enjoy reading your replies. Let me know if you still shoot the 30-338 and what you can do with it with some of the new powders. It has always been an extremely accurate chambering and it would be interesting to know what it would do. Also the 308 norma since they are ballistic twins with slightly different cases. It would be fun to bring back some of the older rounds that people don't shoot a lot anymore and see what they do with the newer powders. If the new design cartridges are better or the powders we use now are the difference makers.
