G'Day Daryl,

Sorry mate, I've been as busy as a One Legged Tap Dancer, so I haven't had a chance to check the .45's barrel twist.

On another part of this, I recently ordered a heap of Dillon bits for my 550B. This order included 300 new, Star Line .45 Colt cases. I weighed them and they came in at an average of 107 grains.
I have a heap of Old but still new Winchester Western unfired cases, that have a roll crimp in the side of the case just above half way, down from the case mouth.
I weighed these and they averaged in at 110 grains.
When you get a chance Daryl, could you please weigh as many different brands of .45 Colt cases, and let me know. Same goes to any other forum readers out there, with various (Remington, Federal etc) brands of .45 Colt cases.

Thank you for your help with this, as case weight can generally give a person a bit of a guide to case strength.

Doh!
Homer
