168 grain Matchking, CCI or Winchester primer, 46 grains of IMR 4064
That was the old standby match load for decades when the M1 ruled the high power field.

If you are shooting at under 400 yards (say one of the 200 yard reduced size target courses of fire, then instead load:
150 grain flat base match bullet, 47 grains IMR 4895. If substituting H4895 reduce by about 0.5 grains.

Single stage press, 2x8, couple of C clamps and you can reload anywhere.

Making this a sticky to make it easier to find for future reference.

Just my 2 bits worth, the load I use.

Don't claim it's match grade but it functions well in my Garand and seems to be more accurate that I am, including being able to keep them in black and making an X the one match I shot at 600 Yards.

Winchester 147gr FMJBT

47.0 grains Win 748

Winchester Large Rifle primers

In large part, powder choice was due to having a bunch on hand for loading .223 Rem for my AR, and since I found reasonable load data for .30-06...

Not exactly scientific, I'm certainly no ammo/accuracy guru, but I have so far managed to avoid damaging or blowing up one of my guns. YMMV etc.

Have you considered a vented gas cylinder plug for the M1s? There are units that use different size 'jets' and also adjustables by loosening or tightening a screw. The venting reduces the peak and impulse pressure in the gas system. If you're willing to do some testing, it allows you to use commercial ammunition that would otherwise generate too high pressure and so risk damage to the op-rod.

Some also claim similar benefits from plugs that are hollowed out to provide a larger initial volume but don't otherwise vent.

So you can leave off the 'Garand-safe' medium pressure requirements when searching for match ammo. Per some of the best Garand armorers I had the opportunity to read in the past, the actual action is more than strong enough to handle any SAAMI-spec .30-06 load; the gas system is the "weak" point for high pressure loads.

The M1 action is ridiculously strong, as Rich says, the issue is modern slow powder providing too much gas at the gas port.

IIRC, according to Hatcher's Notebook, it took 120,000 PSI to crack one of the lugs.

It fired 5000 rounds fine after that.

Tried Mexican Match?

I take a surplus 7.62x51 round.....

Results are excellent. I'm sure the same could be done for '06.

With respect, I'm stumped trying to figure out what possible use Answer B is to Question A.
I'm pretty smart, and although I don't reload (yet), I am at a loss what good a case that won't cycle or feed, with any bullet or powder, is going to do for a surplus .30-06 Garand. Just saying.
Steamforger » Mon Mar 21, 2016 12:18 pm

I'm fairly certain most Garand shooters have some surplus '06 laying around which is what I was getting at.
This still pisses me off re-reading it.
