So just started load development on my ax with brand new 308 barrel. Hands down easiest load development yet every charge between 43 and 45.4 other than 1, grouped at .5" or better with clusters before and after grouping in the same poi. Anyways, a nice big node is between 44.5 and 45.4 ( didn't go any higher.). Absolutely no pressure signs (no hard bolt lift, cratering, or extractor marks).
The load is in lapua brass, br2 primers, 175smk jammed .01 into the lands.
Now I know in my 24" savage 308,with larger Winchester brass, my load is at 44.9gr at 2700fps and that's pretty hot.
I finalized this ax with 24" barrel load at 45gr and those are flying 2780 with a suppressor on. Keep in mind there is probably only about 50 rounds down the tube so far. I attached the picture of the 5 round group that I chronod with my suppressor and magneto speed on. It comes in at slightly bigger than 1/3 moa. Similar to most my groups that day.
Accuracy and speed is excellent, however at that charge with lapua brass and that speed seems very high and should show pressure.
Do I have anything to worry about, or carry on?
