[QUOTE="Doc88, post: 1372206, member: 98886"] I've loaded thousands of rounds of 45ACP, 40SW, and 9mm for USPSA competition. Reliable feeding is a must. A good rule of thumb, similar to loading rifle, is measure the average case wall thickness at the mouth of your pistol brass plus the diameter of your bullet. Be sure to measure the actual bullets you are loading as there may be some variations in bullet brands. Twice the case wall thickness plus the diameter of the bullet is your maximum crimp. Use your barrel removed and unloaded from your pistol as a case guage. The bullets should drop free into the chamber of the barrel. If not, tighten your crimp 001-.002 at the time until they do. Most of my competition bullet crimps measure .002-.004 smaller than the above equation. Every bullet gets case guaged before competition although I now have 100 round case guages that make the process much faster. However, your actual barrel chamber is a very reliable case guage. On the subject of case mouth expansion prior to seating the bullet, you need a little bell on the case mouth so that the jacket or coating of the bullet is not shaved off during the seating process. The bell will be ironed out during the crimping process. Go to the Dillon Reloading website and download an owners manual to any of their machines...550,650 or 1050. This whole process is explained in the manuals very well with pictures. I started on the 550 so that manual may be your best resource. I hope this helps some. I have no experience with the 44 mag though. Good luck. [/QUOTE]
