[QUOTE="davkrat, post: 1076472, member: 6452"] +1 In my 7RM using H1000 and 150 ETips I started seeing pressure signs at 69.5-70.0. In loading the copper solids I've come to the conclusion that they pretty much fall in line with cup and core loads one step higher. In other words a 150 ETip loads like a 168 leaded bullet. Length and bearing surface are usually fairly similar too. Also I am getting somewhere around 3000-3100 fps with that load. I got 3200 running a ladder of R22 but only because pressure and velocity jumped significantly with minute increases in powder. I can run 70.0 gr Retumbo for 3150 or so but accuracy and ES are poor compared to H1000. [/QUOTE]
