While I've never owned or fired an M1 chambered in 7.62 NATO (mine is in 30-06), I would imagine that ammo cost would be an advantage over the 30-06. When buying ammo for my LRB M14, the 7.62 NATO ammo is consistently cheaper than the 30-06 I'm buying for the M1.LTUME1978 wrote: ↑Tue Aug 28, 2018 9:10 pmHow do you like having the Garand set up in .308? I will be traveling to the CMP in a couple of weeks to shoot in the IDPA National Championship. Will be my first time there and probably my last. I need an M1 like I need a hole in my head but have been thinking about getting one for some time. Have been trying to decide between the 30-06 and the 308.
What is good about 30-06 is that when the rifle is set up with the appropriate gas plug (either vented or bored out), you can safely run some pretty hot 30-06 hunting ammo through it without putting the operating rod at risk, if that's something that would eventually interest you. I do have a bored gas plug on my M1, and it definitely eases the wear and tear on the rifle, even when using ammo that is equivalent to M2 ball circa WW2. Other than that, I would venture that it's kind of a "six or half a dozen" situation, as the cartridges are so ballistically similar to one another.
That said, 30-06 is the more historically accurate cartridge to use, although technically the navy did have M1's chambered in 7.62 NATO back in the day. Nothing like seeing that big 30-06 brass fly out of the rifle. People at the range stop and pay attention when you touch that thing off the first time. It is truly one of the baddest machines you'll ever lay hands on.
