There are really 3 factor's to gain the accuracy of the M1 Garand and the M14 (including the commercial M1A):
1) Shooter skill set
2) Accuracy of the rifle (NM tuned of course)
3) Ammo.
All of this will be covered in the book when it comes out mid year. At the moment I'm taking a break from the reloading chapter since it in itself is a beast.
Yep, taking it all the way to the level of concentricity which is a major factor in loading 1000 yard ammo.
Understand that because of the team shooters I knew starting back in 1975, I started shooting PALMA in 76. I'd already been shooting Hi Power matches since 1968 starting with an '03. God help me, it was a 2 grove. We had regular clinics at our range. THe shooters we had were incredible from Noma McCullach (then Zinmaster and I think she's remarried again), Gary Woods, occasionally Mid THompkins (I still use one of his cheater slings) and so on.
Best bet for learning a good skill set? Shooting Jacket, Shooting glove, prone pad and a score book. Since I shoot 100 out to 1000, this leaves the .223's out to lunch. I prefer classics and accuracy all the way out, not mouse guns.
Accessories can be purchased at Champion's Choice in Tenn. Good people, great service. When you google them, make sure to note it's shooting supplies and nothing else... I've already tripped over that one chuckle. Oh, stay in shape... I have to battle myself because I pulled my shooting jacket out of the closet the other night and it's getting "tight" in the gut area... but then I am an old fart. P.S. I am going to Perry this year and if I can't get another NM rifle built for myself, I'll be shooting rattle battle and any other match that doesn't favor the mouse guns.
