since this is basically a "new " cartridge ( 3.82 long 300 win mag)
i chose to shoot a ladder just for velocity. checking pressure as i go.
i will not list the loads as they are unique to this rifle and chamber.
the bbl is nitrite treated, hbn on bullets and bore.
berger 230 bullets and vvn570 powder in federal( yes federal) cases, fed 215 primers
i am trying to find a load around 2900 fps from a 9 twist bbl 27.125 long with a suppressor.
86-92 degrees 30% humidity
2828
2856
2867
2894
2898
2929
2940
2974
2986
NO pressure signs, easy bolt lift, no ejector marks
heat was present in the later shots, might be an issue in a 5 shot string.
its ok..i hit my mark (2900) in the middle if the test)
