I've only had chance once with 8 loads, they were landing well @100yds just need to try and get out a bit more and see if I can fine tune them now.
Using 2oz tin 1lbs antimony and 6lbs lead mix.
It gives me around 21BNH so don't want to exceed 28,000psi, ones I tried were around 22,000psi so room for manouver
