[QUOTE="EKing, post: 3625666, member: 43282"] What powder are you using? I loaded some Remington 210 JSP with 21 grains of H110. They felt like 41 Mag should. In both books (Lyman and Hornady) 21 grains is middle of the road but my fired cases showed signs of high pressure with flattened primers. New Starline cases, GM155M primers I didn't shoot over a chronograph so I don't have that info. Interestingly, the fired cases showed soot on the outside; the cases didn't seal up the chambers fully. Standard practice when seeing flattened primers is to back off of the powder but with H110, things can be a little tricky. I'm wondering if I should bump up the charge and that will possibly reduce the pressure to a normal curve. [/QUOTE]
