451 or .452 bullets, crimping .45acp problems??
--------------------------------------------------------------------------------
Hi all I have an interesting situation that came to light as I started loading for my .45 acp taurus tracker. The tracker has very tight chambers and .45 acp ammo that drops to the bottom of my case gauge works perfectly as does all of the factory ammo I have tried, .475 or less near the web fits, but if the case is .just a hair oversize, .476 near the web, it will not chamber. I loaded up a bunch of rounds with ranier ballistics plated bullets sized .451, all drop to the bottom of the case guage. I also loaded up rounds with Russell cast bullets which run .4525 these rounds stop a rim width from the bottom of the case guage. i also have Penncast bullets that run .4515 when I load with these the rounds almost drop to the bottom of the case gauge, and chamber fine in the tracker. Now the slightly oversize ammo works fine in my 1911s and I have shot thousands of rounds of it. So noticing the problem with the Tracker has made me check all of my adjustments in my Dillon 550. I have it set for the optimum belling resizing seating and crimp as tested with the case guage (Increasing and decreasing settings for the best overall dimensions).
I just can't seem to get the .4525 bullets loaded so thay make SAAMI minimum chamber spec, and drop to the bottom of the case gauge without resistance.
So what gives???? I think the bullet size is the problem or am I missing something here?
And BTW I checked my resizing die settings, its screwed all the way down, and all of the cases will drop to the bottom of the case gauge when they come out of the resizing die. Its only after the cases are loaded and taper crimped that there is a problem.
I thought it was because I was overcrimping and hence putting a very small bulge in the case but I tested this theory out last night by gradually decreasing the crimp and it did not fix the problem!!!
So ist the only answer to use .451 sized bullets ?????
thanks
