[QUOTE="jimbires, post: 1380723, member: 11011"] I plugged his info in quickload .the 300RUM is rated at 64977 PSI . 89.7 grain retumbo looks to be a max load at 64944 PSI , with the 230 berger . his 86.8gr has a case fill of 97% and has 58055 PSI 2762fps with a 26inch bbl . it's a mild load . it takes 100.0 grain of retumbo to get 3121 FPS at 112% case fill , this generates 96625PSI . 91.5 gr ( his 190 load with a 230 bullet ) is 69613 PSI , 102.6% case fill , 2892 FPS . what I'm getting at is ; I don't think the 91.5 gr powder with the 230 gr bullet would cause this . it's only about 5000 PSI over max . he should have noticed the increase in the case fill 97% vs 112% when seating the bullet . if some how he did get 100 gr of powder in the case . 97% is full enough to not be worried about powder position in the case causing a hang fire .
