Hello.
Seeking advise from all 30cal crown owners.
I have FX Crown MK2 .30cal, 600mm barrel, STX Superior 1:22 twist rate liner.
Stock internals, no upgrades.
I am only shooting slugs, don't care about pellets.
Shooting 50 yards, tried NSA slugs, 45gn, 49gn, 55gn, 61gn, 65gn.
Just want to say I am pretty good shot, shot long range rifle for years, so what I am experiencing it's not my twitch or shooting error, I am dead on.
So when I shoot, point of impact shifts, I can put two 3 shots in one hole, then next will go inch to the right or left then again few in the same hole, then 1/4" up and again 2 or 3 in the same hole.
That happens with all listed above grain slugs.
I am on 130BAR reg and my hammer spring tuned for best output.
Speed of the slugs are different, heavy one about 730fps and lightest are 850fps.
Do I need to continue messing with speed of the slug, pick one I want and try slower and faster to figure out what that slug likes?
Or they are too slow that's why they are unstable?
Please advise on what your 30cal shoots well and what reg pressure, what size slug you happy with.
Maybe I need heavier hammer to get more speed?
Please advise.
Thank you very much!!!
