My speeds have fluctuated 2950-2975. As I went to the range today my 100yd group is straight up dog shit, but at 300yds it’s 1”. That’s something I noticing but SDs are good and distance is accurateThanks for the info. Speeds holding up good at those round counts? Have you had to increased powder or chase lands?
Wow....that seems REALLY light. Im using Lapua brass but Im suprised its that much different. The other guy I know is shooting same charge with Peterson brass.36.6gr of H4350 netted me 2794. I know ADG says to down load 15% due to less case volume to start safe, if you add in the 15% it’s like 42gr and sub 2800fps seems a bit slow
That was the max load recommended from the hodgdon reloading page once you subtracted the 15%. No where near pressure signs, and I’ll definitely push it harder once I’ve got more time on my hands since I’ve already got an other load dialed in.Wow....that seems REALLY light.

1. Was that the only charge you tried? Maybe they just want you to start that low to work up slower.
2. Did you see any signs of pressure?
If answers are yes then no, I'd start walking your charge weights up in 0.3 or 0.5gr increments closer to the 39-40gr range.
