Front Band

Postby 5shooter » Thu Jan 08, 2009 9:27 am

I am trying to come up with a large front band that will stop a bullet if it jumps crimp and still chamber easily in my 454 Casull. My cylinder throats are .452". My thoughts on the front band for a tangential ogive 80% meplat .454 bullet are:
.1" long front band
.465 front band bottom diameter
.445 front band top diameter

The case OD holding a .454 bullet is .475". My concern with the .465" front band bottom diameter is crimping. Would a crimping die swage the large portion of the bullet before forming the crimp? Do you know of a good way to measure maximum front band diameter for a crimp die?

I am also thinking I might be able to get by with no crimp after getting the seating depth set so the front band just makes contact with the chamber to throat taper. Do you think an arrangement like that would cause hard chambering from fouling after several shots?

I appreciate the way you think out of the box. That's an original idea.

I've never tried it, so I don't know how that would function.

The most obvious question is how would you size and lube the bullet ?

I was thinking of having Buckshot build a Lyman type lube die with the lube holes drilled closer to the entrance of the die so you would only have to push it to the front band to lube the bullet.
