Thank you
It may be boring for you but I spent some time this morning and could not find a trace of a chart. Even at the Birimgham Proff house. I am shooting 2 1/2 dram eq 7/8 oz reo shells at 1200 fps in a sleeved Island lock Purdey proofed at 3 tons. I have not spent any time trying to find out if this is too hot for the gun but I wonder if they are on the edge of hot or not?
