[QUOTE="BountyHunter, post: 23998, member: 12"] Just one word of caution when chambering your guns throat. You need to have a good idea which bullet you are looking at using. You will find there is a substantial difference in Sierras and custom bullets such as Bergers and JLKs when measuring the length of bearing surface and base to ogive. In my 6.5 there is a .112 difference, which means with my present chamber, the JLk base is actually seated up in the neck to be in the lands, while the Sierra base is down in the case. Measure several different bullets (can use two Stoney Point comparaters on caliper) to get bearing surface or base to ogive lengths. Discuss with gunsmith and he can throat possibly inbetween to allow both to be used. [/QUOTE]
