Re: 338 long range questions?

Your rifle should get quite a bit more velocity even with the 26 inch barrel. My elk load this year out of a 338 ultramag with a 25.5 inch barrel shot the 225 AB's at 3264 fps. My 340 wby will shoot them 3200 fps out of a 28 inch barrel.

Re: 338 long range questions?

Have any load data you are willing to share?

You're obviously doing something alot better than me because I'm not even close to those velocites.

3500fps w/225 WOW!!! Can't imagine brass lasts very long with that load. You must be driving the hell out of those things.

Long Time Long Ranger, no need to apologize, don't worry and I know what ya mean about the attacks...hadn't had any at me personally yet...at least I don't think so. You and I were on a similar thread about a week ago and some guy don't remember who thought he knew it all and went at you. I think it was on the subject of RUM barrels burning out. Little did he know your resume-extensive experience w/rums, smith etc. Thanks.

338-378 wby, 28" Hart barrel 1-12 twist, Mk5 action, 127 grains H-870, 225 nosler AB, 3480 fps. This is not an extremely hot load in this rifle. Another built on a ruger #1 action with 31" Hart barrel 1-12 twist is getting 3550 fps with the 225 AB and Retumbo. I am still working with this one on load development. Can't tell you about brass life there but the primers look good and are not flattened. Both Retumbo and H-870 get over 3000 fps with the 300 SMK in the rifles I have twisted 1-10. Remember H-870 can easily vary 5% batch to batch so work up carefully.

Sometimes you get a slow barrel. It happens to all of us if you buy enough guns. Also a few fast ones just the same. But even considering a very slow barrel you are well below what you should be getting out of your 338-378 Accumark. Velocity loss per inch in the big 338's is small. Maybe 20 fps per inch or less.

Re: 338 long range questions?

I understand every pressure chamber is different but those sound like very hot loads to me.

I'm sure you are already aware of this but there is more to overpressure than flat primers.

My hunting .338 Lapua is a AI AWSM with a 20" barrel. It sends 300 gr. SMK'S at 2650fps. enough to bring down anything at very long distances.. Here it is next to my 20" .308 AI AW..
