Hello there,
I own a Norinco 1911 (could not afford anything better than that here in Italy, very expensive for american imports ) and I have a few doubts concerning COL factor depending on the bullet I use. The first issue is that most american brands are not available so I have to stick with local bullets both in lead and jacketed therefore available reloading data in american litterature does not neccesarily apply. I currently have 230 grains LED ROUND NOSE 226 FULL METAL JACKET ROUND NOSE also. As a rule of thumb, at least with my 9mm, I would set up my Dillon 650 dies using as a sample a factory winchester fmj bullet in order to set up seating and crimping (I would raise the platform and start turning clockwise the dies until I would feel some resistence and then tighten the lock ring). This process as worked fine so far with the 9X21 but with the 45 ACP I get feeding issues from time to time. I use 5.9 grains of vihtavuory propellent which is the starting charge (I believe it tollerates up to 6,4 grains in 226-230 grs bullets). at 32 mm COL (1.259 inches) the finished round doesn't "fall" really easely in chamber. At 31,4 (1.2362 inches) things go better but not perfect. What would then be the minimum and maximum COL for 45 ACP assuming that I would test it always with the minimum charge to stay within safe parameters? How does COL change between Flat point bullets/round nose etc? Thank you for your help.

Costantino
