So, reading on the Bartlett website that their IMR 7383 is roughly similar to 4831 powder, I quickly (and cluelessly) ordered no less than 3 jugs of it to reload for my new 338 Lapua Magnum. (Grab it while ya can right?)
Well, come to find out, IMR 7383 is kinda tricky, plus I can't find any info on it for 338 Lapua, though it should work for that.
Anyone have experience that can help?
Note: I did write to Jeff; no help on 338 Lapua there, and I know what they say about using IMR 4831 data less 15%. Looking for someone that's used it in 338 Lapua...
Thanks!
