I have been loading the .45 Win Mag for 25 years. I shoot a LAR Grizzly .45 Win Mag. I cast a 262 grs. Lee RNFP from WW and Linotype metal. I use loads of Win. 296 or H110. My problem is with hot loads the gun ejects the brass about 15 feet to the rear. I lose a lot of brass. That said the .45 Win Mag is a very good Ctg.
