[QUOTE="Trickymissfit, post: 1137840, member: 25383"] you all are simply masking the real issue here. It's called overbore and in this case massive overbore. Overbore cartridges are well known for a short barrel life, temperamental reloading, and most have accuracy issues. Cartridge shape and size have everything to do with barrel life. The shoulder angle puts the vortex of the flame of the flame anywhere from the center of the neck to deep inside the throat. The neck length is well known to help stabilize the bullet as it enters the throat, and this combined with something like a 33 degree shoulder angle can make for a much longer throat life. Of course a very short neck won't help a bit. I'd prefer a caliber and a half neck length along with a 30 degree shoulder angle. This will help a bunch. Forty degree shoulders seem to be in vogue right now, but they have their own set of issues (doughnut mostly). Case capacity comes in next, but is really a major issue as well. The bore will only handle so much powder period (P.O. Ackley explains this quite well in his books). Ackley pretty much states that the 7mm Remington mag is about perfect, but he also said the 7mm WBY mag is a better design. Guys complain about the WBY, but in a no free bore chamber they are rather nice. Yet very little faster than the Remington. Yet barrel life will be noticeably longer. gary [/QUOTE]
