[QUOTE="270 MKV, post: 699326, member: 52964"] so, I was thinking the other day..what effect does bearing surface have on pressure and velocity... Reason being...I have three bullets I am working with... the lightest one has the longest bearing surface....hmmmm so, was wondering.... if a heavy bullet has a shorter bearing surface than a lighter bullet...what would that do to the possible load...could it indeed be loaded to a similar powder charge as the lighter bullet?? Final velocity would of course be lower...but what would peak chamber pressure do??? [/QUOTE]
