.338 Lapua Magnum Reloading

[Texas1911]

Does anyone reload for this caliber? What's your setup and load for 250 SMKs and 300 SMKs? What gun are you running it out of?

Cody should be a good source of info. He posted a while back about reloading for it.

Didn't spot this until today or I would have thrown you some info. I'm loading 94 grains of Retumbo behind the 300 SMK in a Lapua case with a CCI LR Magnum primer. I get 2785 fps out of them and they run sub MOA out of a Armalite AR30.

Got any 250 SMK loads? I'm not sure the TRG is a fan of 300s ... I was told that the Finns get the best performance out of the 250 gr. Scenars

I've only shot a box of 250s, never loaded any. I've heard a lot of people say the 250 gives a bit more accuracy out of a lot of rifles but I lucked out that mine liked the 300s well enough as the BC is fantastic on them. I do have to trim the 300s with a meplat trimmer to really get them uniform and bring the groups in. Sierra cant seem to get them right and it really shows up on the big bullets.
