No crimp groove

[RealGun]

I have the 454 lead bullets I ordered from Lucky13 http://lucky13bullets.com/index.php?main_page=product_info&cPath=26&products_id=143. They are RNFP PB (plain base). There are three bearing bands but no crimp groove. There is a small ledge before the ogive. I crimped 12 test rounds over the edge of that last bearing band but now have a 45 Colt COL of 1.515. There is a lot of bullet inserted, and the load is substantial for a NMBH (10.0 Unique).

The crimp location makes sense to me rather than crush the bullet, but should I be concerned about the reduced case volume with so deep a bullet insertion? The bearing surface is 3/8" (.375) long. The bullet is in far enough for the crimp to close around the base of the ogive. The case trim length is 1.270.

There should be no problem provided you worked up your loads. I've loaded some MBC Cowboy loads for a close friend which can not handload any more due to a shoulder issue. With these they have a crimp band but it puts a lot of bullet into the case. He shooting 4.5gr TB which are powder puff loads, which makes it fun to shoot. Your max OAL is going to be what fits the cylinder in a revolver.

Think I will load a test set of 12 in 9.0 and 9.5.

I doubt you will have an issue in the large .45 Colt case with standard pressure loads. If you imagine a crimp groove on those bullets they would not be seated that much deeper IMHO. That and the large case operating at low pressures tells me you are OK. YMMV of course, but I see no problem if you work up in your usual way.

I would aggree with the others here, having loaded a ton of .45 and .454 Casull (.454 Cadillac as my phone likes to call it haha)
Anyway, as was already stated, work up the load as you would normally do anyway when using new components and you will be good to go. Start at maybe 9.2 load 10 of those, then 9.5, and if all goes well 10 will be next. I wouldn't say it's all that hot of a load for a Black. If it was a new Vaq I would aggree, but I've pushed some super hot loads of LilGun through my Black over the years of owning it. Essentially using it as an (almost) .454 Casull before I actually had one. It took it in stride.
