[QUOTE="elktaker, post: 1095405, member: 86786"] If anyone is still reading, help/thoughts would be appreciated. WENT TO THE RANGE TODAY to sight in and fireform (norma 270 wsm, COW method) First shot 62gr of Norma MRP (168 berger VLDs) - Bolt felt a little sticky. It is hard to tell with Savage cocking the fire pin on the lift, but felt slightly sticky. Velocity read 3081 and 3169 for 2 rounds at 62gr about 4 minutes apart. I am not sure if the chronograph was working right because I got errors on the next two shots at 62.5gr. With 62.5 had a heavy bolt light and lite extractor marks. Both of these loads were .010 off the lands, I have to check on OAL but think it is about 2.9". This brass from my other barrel and was full length size and was .0005 larger than my no-go gauge. I also fireformed 40 pieces of brass they all measure .001 larger than my no-go gauge so I believe my head space is okay and maybe on the tight. Luckily, I got the gun sighted in enough for load testing in the 4 shots. What load should I use for developing my seating depth? I was going to do 60 gr but seems like that may end up a grain or so from my max. Thanks for any help, not sure why I am seeing pressure so quick had similar case with my stock barrel. It did not matter if it was fresh or fired brass. [/QUOTE]
