[QUOTE="Mikecr, post: 894504, member: 1521"] If there is an implication somewhere that barrel length doesn't change %powder burned -it's wrong. That heavier recoil with badly designed cartridges(like a 30-06) is the result of unburned powder added to bullet mass. Some is not burning in the chamber, and some not in the bore at all. That fireball at the muzzle is powder burning off outside the bore, and you can bet this excess muzzle pressure which is slapping the back of boat tail bullets, isn't 'good for' accuracy. It doesn't make sense to me that people would want to burn a lot of barrel killing powder, from large cartridges, in barrels too short to take advantage. This to me makes about as much sense as using light for cal bullets in large cartridges. [/QUOTE]
