MP Molds 450BM- C- 275 grain (Cast) for 450 Bushmaster/ 45 Colt/ 454 Casull

[Tripplebeards]

Taper only or they won’t feed in my American. I taper at .474”

[bluejay75]

Two different crimp grooves for two different purposes. I think we are in stride agreeing to disagree.

The 450bushmaseter head spaces off case mouth. So either a “custom jab crimp” or a taper is all you CAN DO. I haven’t had any issues with just taper crimping.

IMHO people get all too hung up on crimping in general. Crimpings IS NOT neck tension.

I use a Lyman M-die and find improved accuracy overall loading this cartridge.

It's advertised as a 454 casull bullet, also. But you probably don't need to crimp that either?

Collett crimp is the strongest and most consistent period. Hard to over or under do that one.Wont roll a crimp. perfect for boolits without crimp grooves.

In this instance I would say you are correct. Lee DOES NOT make a Collett Crimp die for 454. I sent them an inquiry as to why. Cost would be 25.00 plus shipping. They make it for 460SW and 45 COlt...Even 500 SW but wont even offer it out of the custom shop for the 454. I am a rookie reloader and it cut my groups in half and lowered all of my SDs.

All fixed up gents...

[tradbear55]

I forgot to put lube grooves in my order. Sorry. I agree that the collet crimp is probably the best thing that Lee offers to reloaders. Unfortunately, they are not available in all of the calibers.

So I take it that this might not be okay for a 454 Casull in a lever-action or the 315gr one for the 450Bushmaster?
No crimp groove???

This boolit’s nose is tapered and has rounded edges so it should feed much better than others lve seen for the 450BS. IMO it will work great but I’d tell you to get crimp grooves.

Yeah,bugger would have been a good one

Understood...Not being a prick, but as listed/described/explained this is a 450 Bushmaster bullet that can work in a 45/454/460...

Like most folks, I DO prefer to heavily crimp most J-Bullets in the 45/454/460 too. But lead bullets, I find better results with minor taper crimping. (all calibers)

Im going to post this in the equipment thread...but here goes.

I was told by Lee to have as many people as I could to contact them to run the 454 Casull as a Collett Crimp and they would offer it as a standard offering. My point was that there are more 454 shooters than probably 460 and 500 SW shooters combined.

Hey bluejay75
Does that number get Laine?
I would have to ring from Australia.

I bought a 460 S&W collet crimp die and just cut it down to fit the 454. I then took some number stamps and marked it 454.
Works great.

Can you share what you cut. Maybe post steps in reloading tools.

[lar45]

This is what I did to cut down a 460S&W factory crimp die to fit the 454 Casull.

Screw your 460 die partway into a press. take a punch and a small hammer to tap the collet insert out of the die body. Go easy and don't break anything.



Once they are apart, take a sharpie and mark the die body at 2.000", mark the collet at 1.285".
Cut them off with a hacksaw, dremel, lathe, anything that can make a nice clean cut.
Be sure to cut the collet a little long, so you can fine tune it to get the crimp where you want it. Mine is finished up at 1.285"
Be sure to debur your cuts.



I took a set of number punches and marked the collet 454.
Clean everything up and slide the collet back into the body and give it a try.
Let me know if anything is not clear.



Here's a link to the 450 Bushmaster forum where they are talking about modifying Lee FCDs to do a Legendre side crimp to help hold cast bullets firmly in the case.
Lots of pics and step by step instructions.

Apparently Lee say to use the 45colt/454 FCD,what say all you?

That is a completely different crimping die. That one has the carbide sizer at the bottom to make sure your loaded rounds will chamber.
The one that we're talking about is the Collet style crimp die.

Hey Lar45
Thanks for enlightening me,I thought it was the FCD die and thanks for posting how to modify the die,I might have to do that and then might be able to get the mold,winner winner.

[Tripplebeards]

I threw some links out on a couple different websites to try and get some more orders for this mold. Was hoping we get this one going and mold in hands soon!
