Ok so I have cast about 1000 rounds over the past two weeks of WW bullets that are .452 230gr tc's but don't have a crimp groove. I tried crimping them and at first all looked good till I noticed one sitting a bit out of the case. I just realized of the 50 cartridges I just loaded the crimp doesn't seem like it will hold, the boolits can be pulled a couple millimeters out of the case with my fingers. I increased the crimp and it did not seem to make it any better. I'm loading .45 colt for a wheel gun so I know that I need a good crimp to keep the boolits from backing out during firing. Am I going to HAVE to buy a different mold with a crimp groove? I was really wanting to be able to use one mold for both 45 colt and ACP.
