M1 Garand Brass

[Clickjack]

I did 50 rounds at 3.20 depth. Factory crimp. My books don’t seem to have a minimum OAL. But from what I read on the internet that. 3.20 is with in the saami guidelines?

Read this -

I purchased a Turkish 38 type riffle I chambered a round of Turkish ammo, pulled the trigger and the smoke appeared and was accompanied with a whistling sound. The ammo was 70+ years old and the rifle was older. I knew the hole in the primer was going to cut the bolt face, so I did not fire another round.

Instead I changed the firing pin spring, the original spring would not hold the pressure. When that happens pressure in the case exceeds the ability of the firing pin spring to hold the pressure; the winner? Pressure inside the case.

I have a book that list three different lengths for the 30/06 because the author claimed there are three different length.

Minimum length? I am the fan of the jump start, I want my bullet to have that running start. I want my bullet past the rifling before the bullet knows the rifling's are there.

You don't need a small based die for reloading the Garand. Standard die works just fine.

Here's a link to Garand reloading data.

Master Po's comments
These loads only duplicate military spec. velocities for the given bullet weight, using commercial cases and powders. If you are using military cases, drop all charges by 2 grains.

If you are looking for accuracy, drop all charges by 1 grain and work up .2 grains at a time.

Master Po's Ancient M1 load secret
This is my personal M1 load I use in my CMP M1. It will shoot better than Master Po can. I worked this load up, as you should for your own rifle.

Remington .30/06 cases, flash holes deburred and weighed within 1 grain.
Federal GM210M Primers (Master Po has heard the horror stories of Federal match primers in the M1/M1A rifles. If you're squeamish or new to reloading, use Winchester Large Rifle)
47.0 grains IMR 4064
Sierra 175 grain MatchKing
Overall length 3.340 inches

This load, in my M1, duplicates almost perfectly the M72 match load specification with a very low standard deviation. Groups off the bench run 1 - 1.5 inches with the original 1945 barrel on the rifle. Of course, Grasshopper YMMV.

I have small base dies, I do not use them but JIC as in just in case I need them.

The M Garand has clearance cut into the chamber. I am hoping everyone know that and I am hoping everyone know by how much because I do not want to the book out. The book listed three 30/06 chambers.

I have two 30/06 reamers; the usual one and the Ackley improved one.
