I just picked up a new rifle in 338 lapua AI with the 40 degree shoulder. I'm loading up some fire forming loads now with 88gr8 of H4831sc and SMK 250s and some 250 berger. Basically burning up some partial boxes of stuff i've got laying around.
The question is when I get ready to load the actual Improved.rounds do y'all have any suggestions on powders that work particularly well in this round? I have a good supply of RL33, which I've had great luck with in the regular lapua. Also have H1000 a little Retumbo and even some Ramshot LRT. I will either run the Nosler Custom comp 300gr. which I've had really good luck with along with the RL33 in standard lapua or I'll be running the 285 ELD-M. I like the idea of that 285 and being abke.to maybe drive it a bit faster. The guy I got it from said 107.5gr of RL33 was giving him 3000fps with the 300gr Berbers. It's a 28"proof carbon barrel if that helps. Any help would be appreciated. I'm just kind of looking for some starting points or advice from some guys that run these.
