[QUOTE="Centre Punch, post: 90379, member: 3048"] Hi 30-06, I had this problem when developing loads for my 243 using H4350 before i joined this site. A hot load on a cold day turned into a super hot high pressure load on a hot day. [img]/ubbthreads/images/graemlins/shocked.gif[/img] I had to beat the bolt handle up with a mallet and on drawing back the bolt the case was stuck to the bolt face. Brass had flowed into the ejecter hole and jammed it in the "in" position. Some of the primers were pierced, accuracy was crap Luckily i had some loads made up with Win 760 but my accuracy did not improve [img]/ubbthreads/images/graemlins/frown.gif[/img] I asked my smith about this and after he had stopped laughing he said i had a bit of high pressure and the loss of accuracy was due to massive copper fouling. [img]/ubbthreads/images/graemlins/frown.gif[/img] 10 hours of 15 minute periods with Shooters choice copper remover got rid of the fouling and a change to H4350ex cured the cold weather/hot weather pressure problems. Ian. "I meant to shoot the pike but the duck got in the way" [/QUOTE]
