[QUOTE="Sean Wilkerson, post: 1100489, member: 84220"] Thanks for the good advice. Im glad to hear from you because i know you have considerable experience with customs rums. I tend to agree and that option has always been in the back of my mind. I've never considered the standard chamber handicapped in any way and have had great success with their accuracy. Bolt click can indeed be an indicator of higher pressures but I haven't noticed any other excessive pressure signs accompanying the click and it is nonexistent with newer cases. What is obvious though is the charge limit of the match vs saami chamber. Whereas it is common to be able run a standard rum well over book max with certain powders, this one maxes out around 91.5 of retumbo with a 200 smk. The freebore is .112 I think, roughly .100 shorter than a factory chamber, so I'd bet that's a contributor to this. I'm having to jump accubonds .050 to get quality accuracy anyway, so in this case, short FB doesn't seem to be worth the trouble. It shoots smks great at .020 but it also shot them great with a hellacious jump, before the rebuild. Thanks for your time. [/QUOTE]
