375 ultra mag

I have a 375 Lapua improved I built and then lost interest in due to dedicating all my shooting bandwidth to ELR. I have some 350 Lazers I need to run in that rifle and see what I can end up with.

It is throated very long, so velocity should be good even with a 26 in barrel.

Rum and not the liquid said:

I run 352 mth and mtacs at 2695 out of a 30" proof barrel with suppressor 5 round raged hole. I just reached out to a mile over the weekend but didn't get a hit on the 2k due to my inexperience with wind at range

I run 96.8 grains of adi 2217 which off the top of my head is h1000 for those who went to the moon
