[QUOTE="Varmint Hunter, post: 207169, member: 313"] I would disagree with your gunsmith, primarily because there doesn't seem to be any reason to suspect that is the problem. The FIRST thing I would check is the powder charge. You shoud be starting with loads that are 15% below maximum or just use the lighter charges listed in a reloading manual. You may also want to confirm that you are using the EXACT same powder as is indicated in whatever source that you used. I might add that you should NEVER use unconfirmed loads that are listed on ANY web site. There could be other possible causes of excessive pressure like cases that are too long, wrong primers, etc but I'd look at the powder charge first and then look at less likely causes. Arbitrarily seating bullets deeper into a case could actually cause pressure to climb, however, 1 millimeter shouldn't make that much difference. If bullets are loaded to the length that is indicated in the appropiate manual then you should be fine when using a factory barrel or SAMMI chamber. [/QUOTE]
