Re: 338 Sin

Thanks for the post, geargrinder.
While I think this is a fine concept, I don't believe you will be getting the same performance as the 338 RUM or 338 Norma due to less case capacity. Using a fatser powder like Vit N570 will help thou.
But, for the 225gr AB, with a 26" barrel , in a light weight rifle, I think this will be a great caliber. I beleive it will outperform the 338WM
For the 300gr SMK, I will stick with the EDGE or similar caliber.

Re: 338 Sin

Just ran across this thread, very interesting indeed.

Devin chambered a 7-300WSM Brux barrel for me and did a great job. He also worked around my being out of the country unexpectedly for awhile at the time.

Great guy and great to do business with. I hope this project succeeds.

Re: 338 Sin

I finally got the brass figured out and it is quite easy: form die, trim, hydro form, and FL size. Here are a few pics of what I did.


Form Die



center one trimmed to length



hydro formed case with 250gr SMK seated to 3.5" (std savage long action mag length)





I need to remeasure the neck length because I got in a hurry and I believe I cut it to short, I know its at least .015" short. What can I say I am a little excited haha

Re: 338 Sin

I am loading up some test rounds now to see where I will be in compared to 338 Rum loads. I am starting with 90.3 grs of retumbo with a 200 gr bullet over it. I feel that I should be very safe starting with that and working up. I plan on shooting tomorrow, I just need to snow shoe for a 1/2 mile to get to the range.

Re: 338 Sin

First trial loads where fired today. With 91.7grs of retumbo I hit 2936fps with a 200gr bullet and no pressure signs. From what I see on reloaders nest I am getting pretty close to 338 rum performance. I am thinking about trying h1000 as it has a faster burn or maybe Ramshot magnum. W#hat do you guys think?
