LlindeX-
Thank you. Like the man said, even a blind squirrel can find acorns occasionally.
I've been using the unmodified die myself recently. (I think somebody on the forum suggested this technique, but I can't find the post.) The broader crimping band in the unmodified 45 Colt die applies pressure without noticeably putting a crease in the case or deforming the bullet. The trade-off is that it doesn't increase bullet retention in the case quite as well as the narrow ridge of a modified collet.
I've been working with some very light frangible bullets in the 450B. The manufacturer of one of these bullets has warned against too-tight crimps, either taper or rolled, because such crimps may fracture the bullets. The broader crimp of the unmodified 45 Colt die produces an increased bullet pull without excessive circumferential stress on the bullet.
