As most of you may remember, I have a 9.3x62 Garand.
This rifle has a Lothar Walther barrel and it was built on a Breda receiver. The rifle was test fired using a Schuster gas plug. The gun cycled properly in that it would feed and extract ammo properly. But the timing was off. The rifle would prematurely eject the clip after three or four shots. I learned that the extra heavy 300 grain bullets could affect the proper timing of the rifle and that the timing problem might be cured with a modified operating rod catch. ( Holbrook device) I now have a Holbrook device installed and the 9.3x62 Garand will shortly be test fired. Stay tuned. This is going to be good |

I do want one of those! I have little need for such wretched engineering excess, but I really want one!

I was looking the pictures thinking I wonder how many Garands fluffy has.

Fluffy, would anything other than a different barrel be needed to make a .35 Whelen Garand?

However, still need pics of loaded ammo next to 5.56 and 308, and preferably something like a .375. And a list of bullet weight, english caliber, and fps. |

I want a regular M1 Garand but you sir are inspirational for a man that likes both SA rifles and safari calibers. 9.3 is rather high up on my list for a full stock rifle. To think a man is making it work in an auto is rather neat indeed.

I've nothing to add, except that this is awesome.
There used to be a shop somewhat close to me that did big bore M1 builds, but I believe they closed years ago (mccann industries, or something like that, iirc) Also, I've had the chance to speak with John Holbrook several times back before the gunshows here got lame. He was an interesting guy. |

Quoted: Here's the modified 9.3 receiver. The internal receiver ribs were modified. They were thinned using tungsten carbide tooling. https://www.ar15.com/media/mediaFiles/234818/20190227_150317-1837628.jpg Unless you thin the receiver ribs, you can only hold perhaps three 9.3 or .35 Whelen rounds because the bullet noses get jammed against the receiver ribs. The original M1 was designed for the .276 Pedersen and it really shows when you attempt to adapt the rifle to larger calibers. Those ribs were designed for a 7mm rifle and while .30 caliber will work, once you go beyond .30 caliber, you run out of room for the bullets noses. Here's a clip of 8 rounds of 9.3 ammo. As you can see, it is a tight fit and unless you thin those internal ribs, you cannot fit a full 8 round clip. https://www.ar15.com/media/mediaFiles/234818/20190227_150114-1837719.jpg View Quote I have only fired the 9.3 Garand once and I difficulty latching a full 8 round clip into the magazine. I suspect that the extra weight of the cartridges has something to do with this. As you know, the operating rod spring also provides tension for the follower assembly. And with the 9.3 Garand somehow there appeared to be too much follower tension. I think I am going to experiment a little with different operating rod springs and see what happens. |

Because it will still work once you increase the bullet diameter by 24 thousandths of an inch. But once the bullet diameter is increased beyond .30 caliber, everything gets cramped. |

Something else to report:
I fired the 9.3 Garand in early 2019 and I put only about 30 rounds through it. I decided to inspect the rifle before taking it out today and I was shocked to see green copper fouling at the muzzle. I ran some Wipe Out through the bore and the patches came out solidly blue. Patch after patch came out that way. It's clean now, but I've never seen so much copper fouling. Anyway, its clean now. |

View Quote I guess the tooling was already in place and changing it would have been a waste of time since it worked either way. |

It could have been some kind of lube or machine oil from when the barrel was installed. |

I used the 300 grain Hornady solid and Prvi Partisan 286 grain factory ammo.

Your 9.2x62 Mauser conversion makes a .35 Whelen conversion look quite vanilla by comparison. Safari Garand indeed.
|
|
It is -17 degrees F here today and I just want to see if I can fire a clip or two.
This is basically a function test. |
|
Well I'm tuned the hell in. 9.3 is pretty versatile with bullet weights/velocities from 232gr norma/2700+ to 320 woodleigh/2300fps.
I had picked up 500 250gr Barnes bullets for $100 a while back. The round is for much more than bear and pig as Cape buffalo have been taken with single 250 or 286gr Barnes. |

Sooo, Garands in custom calibers...
How does one learn this power? |

Also been watching you from afar for awhile. Good stuff OP. Attached File |
