[QUOTE="Fiftydriver, post: 70171, member: 10"] Buffalobob, This is simply a case of the chamber dimensions being on the loose side. When you chamber a round in a loose chamber(factory), the loaded round will sit in the bottom of the chamber if you will. Gravity will pull it down. When it is fired, the bottom of the case is already laying on the chamber so the only place for the case to expand is up. The expands the case to fill the chamber and results in the buldge on the one side of the case. With repeated firings, this generally will even out all around the case to some degree but is it simply from the chamber being much larger then needed. The only way to cure this problem is with a rebarrel job and a properly designed reamer that will limit this expansion and reduce this buldge. Once the case is fireformed, and if you neck size or partial full length size, you will generally get good grouping if the rest of the rifle is put together well which it sounds like it is. Repeated full length sizing will work harden the brass and could result in some case body splits. This is typical in factory rifles, some to a higher degree then others but very common. Nothing to worry about and don't try to get rid of the buldge with your case sizing. The case is just expanded to fit your loose chamber and let it stay that way for best results on target!! Don;t give it another though and have fun with your little hot rod!! Kirby Allen(50) [/QUOTE]
