I may be "behind" on things but I ran across what was listed as "Lee's new collet crimp die" for 45 Colt on flea bay. I have never seen one before so I'm guessing they are fairly new. A quick check of Titan's site and sure enough, they show about five different calibers - 357, 44 mag, 45 Colt, etc.
I use their collet crimp on my 8mm and 30-30 and they work well . . . but straight wall pistol cartridges?
I am thinking about my 45 Colt loads - I strictly use the old style traditional FNRP in 200 and 255 grain - put a roll crimp on they easily. On several other designs, I've just used a taper crimp and have never had an issue in regards to boolit jump in my Uberti Cattleman.
I have thought about getting some powder coated 230 grain just to try for fun - in the traditional "ball ammo" style boolit for the 45 ACP - they wouldn't have a crimp groove but I figured a tight taper crimp on them wold be more than adequate.
The write up I read on the flea bay listing touted how easy it was to use on the "difficult to load" 45 Colt. Huh? i find the 45 Colt to be oe one of the easiest cartridges I've ever loaded.
So . . . why the marketing of a collet crimp for these pistol cartridges? Just something "new" for people to try or do they have a real advantage over a roll crimp or taper crimp die? I realize that a lot of these cartridges are now being used in lever guns, etc. - is it primarily for them or just "hype" and a new product to make sales? It's sort of advertised as making a secure crimp as on rifle cartridges and no crimp groove is necessary as it will creat it's own?
Most of what I've read as far as, say the 38/357, 44, 45 Colt, etc and lever guns is that a decent roll crimp is all that's needed. Is there something I'm missing? I'm certainly open to new things and would not be against trying one if I thought there was an advantage for it but off hand, I'm not seeing the need when you already have a good roll crimp or taper crimp . . . . unless there is an advantage to a rifle type crimp in a Ruger Only type load?
