[QUOTE="Lrt307, post: 1380737, member: 57068"] I agree that the 91.5 charge doesnt seem to me that it would cause this by itself. I have run 93 grains Retumbo with the 230 @ 3075fps. I am wondering if there would be any possibility on barrel constriction in the -10 temps? How long did it sit before it was fired again? I have also found that my 71 grain retumbo charge in my 7mm is perfect from 10°f all the way to 80° and up. If I shoot this load below 10°f like around 0°f it shows high psi! [/QUOTE]
