I bought several boxes of the CMP Lake City 69 M2 ball at a sale for cheap this summer..I figured I would pull the FMJ,and replace it with a 150 gr soft point..I pulled some bullets,and weighed the charge,and was averaging just shy of 45 gr..I assumed the powder was IMR 4895,and they were just loaded light.I got a box of Sierra Pro Hunter 150s,and started working on some loads using the salvaged powder..I settled on 48gr. because I was getting good groups,and no pressure warning signs ..Well just today while fiddling around on the computer I discovered that Lake City used a powder called CMR 100 from 67-69,and this powder is about like IMR 3031..I loaded these for my 7600 figuring they would be a nice mild round for the pump..I have shot at least 10 of these through it with no extraction issues,or extremly flat,or cratered primers.I've not noticed a hard kick either..I have over 60 rounds of these loaded..Am I good to go,conciderin the gun seems to like them,and I'm getting no warning signs from extraction,or brass?...I don't have a chrono,so I don't know the velocty
