.338 LM load data

[Mcoop8]

I just picked up a .338 LM. It came with some 300 gr Sierra MK. This is the bullet the gun was barreled to run. it has a 1 in 10 heart. I looked in the books that I have and I can only find load data for up to 250 gr. Any idea where I can look to get heavy bullet info?

Have you tried the reloading depot under this heading? There should be a few loads for you to try

Thanks for the direction. I found 2 starting points. 90 gr H 1000 and 91 gr Retumbo. Ill start lower and work my way up. Thanks.

My loads with the two powders you mentioned are 93 gr H1000 and 95.3 gr of Retumbo. Both loads are around 2850 with the H1000 being the more accurate of the two with a lower velocity spread. You can't go wrong with either powder choice.
You may also want to check the reloading depot. There is an abundance of established 338 loads there.
