New Addition M1 Garand in 7,62

SKIP · Nov 18, 2017

H&R 7,62 to go along with my H&R in .30.
I test fired this rifle last week and sealed the deal this morning. Included was 100 rounds of LC 7,62, 40 enblock clips and gun case.
It was cloudy and I was unable to see any hits until a ceasefire was called.
Not too bad for a 70 year old.

Nice. Does the 308 version need any work, or does it shoot any 308?

It shoots factory and my reloads. There is a aluminum plug in the receiver to prevent loading 30-06.

Are you worried about using heavy loads in it. I beleive Garands use lighter loads in 30-06.

Just checking if the 308 M1 has the same restrictions/constraints as the 30-06 M1 regarding the use of certain commercial loads. The 30-06 M1 needs some modification before it can use certain 30-06 commercial loads that may damage the op-rod.

All my reloads for 7,62 and 30-06 use 150 FMJ without problems.

Damn that's nice

I beleive what you have is a Garand built with Italian modified parts. The Italians shortened the barrels to chamber 7.62 so the op rods also had to be shortened. The give away is the 7.62 mm/2 stamped on the op rod. USGI 7.62x51 garands where not stamped on the op rods

With 1:10 twist, they are more actually accurate with a heavier bullet. The issue is with the gas system and operating rod, with bullets heavier than 180 grains. But that's in 30-06. 308 loads have less propellant, so produce less gas at the muzzle than '06, and there aren't many commercial 308 loads even at 180 grains, let alone heavier. Less gas = lower peak pressure on operating rod, although I'm ignoring port size to keep it simple.
My 308 Garands eat everything commercial just fine, and are at their most accurate with 168 grain SMKs. Lighter projectiles give me larger groups, across all the Garands I own, 308 and '06.

The original '06 round for the production Garand, the one it was designed around, was the Cartridge, Caliber 30, M1 Ball. That had a ~173 grain projectile. M2 ball reduced projectile size to 150 grains, supposedly because of training range limitations at US bases. It seems the larger projectiles had too much lethality at a long distance when trainees overshot berms.

308/7.62 Garands are not load sensitive as the 30.06 Garand. Any normal load commercial ammo is fine as long as op rod spring is not worn

I built a .308 Garand on a pre-war Springfield Armory receiver...match barrel, op rod, laminated stock and carefully assembled. It's maybe the most accurate rifle I own...at least most accurate semi-auto rifle I have.
