Cast Bullets in M1

Postby rowe_s » Sun Jan 19, 2014 10:34 pm

Anybody here ever work with 150 grain cast bullets in the M1?
I'm going to give it a try, be nice to know a load to research and start from.
Found some loads for heavier bullets on CastBoolits.com but I have a 150 grain mold I would like to use.

The book I have list them, but not specifically for the M1.
You have to have enough gusto to operate the gas system, I am not sure you can drive a cast bullet that fast and not have it lead up the barrel.
2000fps or less unless you cast really hard brinnell.

I'd suggest searching around castbooolits more on that.

(later)
Heres one:

I'd suggest the 200gr lee mold, as did several in that thread.

Also going by that thread you could try some loads from the Lyman Cast Manual. I show for 150gr Rx7, unique, imr-4198, A5744 and imr-3031.

This thread had some interesting yet unconfirmed points (I don't own a M1)

A5744 is an excellent cast load powder, but $$$$. Rx7 is close and cheaper, but harder to find. I found H2400 recently, also in the cheaper category since its a magnum pistol powder, you also use less.

Shooting cast is very addictive.

Ah the quest for cast in the m1 Garand! :D Motopic is heading you in the right direction, Cast Boolits. The thread below set me straight on the do's and don't, the op-rod worries, lead fouling the gas port, etc.

I bookmarked this thread as the BobS Load.
http://castboolits.gunloads.com/showthread.php?27055-M1-Garand-loads&highlight=BobS+4350

Starting at thread #13 BruceB states "USING CAST BULLETS is NOT the same as using jacketed bullets in a Garand. The precautions for powder speed observed in JACKETED loads DO NOT, repeat NOT, apply to cast-bullet loads in the M1. In this appplication, such precautions are myths and old-wives' tales."

Later in thread #15 BobS proves that even 38g IMR4350 can be with a 210+ cast bullet. IMR4359 is something that according to most that is a MOST SERIOUS NO NO for the M1....... but as they show in a different ball game with cast bullets.

I've loaded my M1 with IMR4350 and H4895 both with great success. Slugging my bore was necessary to get past the leading then several load work up to get good cycling and finally good groups. I was chicken to just jump in on the BobS's load data to begin with.

Here is another EXCELLENT post that will help you down this path.
