338 WIN MAG

Does anybody load a 338 ? Starting to work up a new load. Wondering what power you are using IMR4350 IMR4831 or RL19 and how far off the lands. loaded some with IMR4831 but did not group very well.

Re: 338 WIN MAG

I loaded 20 rounds with 69 gr. of IMR 4831 and had some trouble grouping two weeks ago. It was shooting 225 gr. Nosler Partitions. However, it was hot that day so I am not giving up on the load just yet. I want to try it again when it is cooler. I think some of it was me too as I was getting used to shooting from a lead sled.

Re: 338 WIN MAG

What is your process for working up a new load? How many do you make, and how do you go about testing them at the range?

Re: 338 WIN MAG

I would think the 4831's would be a tad on the slow side for the .338 Win.

I'm thinking my first try would be with IMR-4350.

Next I'd try H-414. After that, IMR-7828.

Betcha you'll find a keeper in there somewhere.

Re: 338 WIN MAG

I use RL-19 in mine and have very good results with it. I always load right to the specified COL.

Have you tried R-17, Kudu ??

I have not. But some reading suggests it may be the best thing since sliced bread in cartridges with similar capacity:bore diameter ratios as the .338 WM.

Haven't tried it. With my RL-19 results, I never felt the need. I load 250 grain Hornady Interlocks and they have flattened everything that I've fired them at.

No use to fix what ain't broke. Nope.

Re: 338 WIN MAG

I like a little faster powder in my .338wm, as like just about everything I own use H-4350 in mine, I'll sacrifice a little velocity for awesome accuracy.. I use the 225 partition or the 200 x-bullet, surprising they have almost the same impact point, no adjustment to the scope is needed..both shoot five shot groups around an inch, could be better but I can't handle it off the bench past three shots
