Re: 338 Lapua AI shooting paper plates from 2350
I am having a 338LM Imp built as we speak. I have had a 338LM for the last 2 years, but want some more punch out at long range. It will be throated for the 300 grs Berger OTM.
I have been using Viht N570 powder, and will continoue to do so in the Imp version also. Barrel will be 32" long. Any thoughts of how much powder I can use?
