Dave,

I am getting sub .5" accuracy and a MV of 2937, ES 14 SD 7 with the Nosler 250 gr AB in my stock M700 LSS using Retumbo.


Here is a link to read-
Nosler Reloading - ammunition, hunting, shooting, and performance reloading expertise from the source.

FWIW, the same Retumbo load with the 250 gr PT yielded an avg velocity of 3024 fps from my Oehler 35.

Who says Ruger #1's aren't accurate? I had my #1 338 win. mag. re-chambered to 338 RUM and consistantly print under 3/4 inch groups with a 200 gr. Nosler Accu-Bond and 96 gr. of 7828. And I get 3280 f.p.s. over a pro-chrony. At 2" high at 100 yds. this gives me a no hold over on Elk out to almost 400 yds. But, even in the heavy #1 I found that a good brake made it a lot more shooter friendly. 7828 was significantly faster than either rl-25 or h-1000. Give it a try. Gerry Wood Cody, Wyoming

Re: 338 Remington Ultra Mag load data desired

Hey Guy's Just trying to get a BUMP start on this old thread.

Any new Berger 300 OTM Tactical Load data for the 338 RUM?

I thought I would keep this post going because, you really don't find much on the load data of these big boy's.

I have some of the OTM's I'm just trying to get the rifle put together, For some good spring spring.

Re: 338 Remington Ultra Mag load data desired

ok guys I have read from first post to last post I am trying to grasp how a longer barrel changes my velocity I get the physics side but how will my charge likely vary from someone with a 26" barrel I have a 31" barrel on my 338rum with a custom throat for a 4.088 Col (single shot) I'm thinking I need a slower powder is this accurate
thanks
