As I move along with this I will post updates here and what thread #s I updated
it was a toss up of this and a 1952 SA both SG.
This HRA has the highest readings of my SG's. It did not shoot very well when I 1st received it. Disappointment really. It took some working of the hand guards, gas cyl and a recrown to get it shooting HXP @ 4 MOA and averaging 2.75" MOA with reloads... thats not bad but this rifle is a mix master of parts and will need a new stock also. I will be useing a Criterion barrel from the cmp. Been putting off a "new" barrel install for a while now. So far only a few used barrel swaps.... barrel to be ordered after the new year
http://www.northeastshooters.com/vb...cy-Improvement-of-HRA-with-spring-replacement here is a little history of this rifle.
I will be more than happy if the new barrel delivers under 2.5 moa or better consistently with reloads.
HXP ammo the best lot I have is 1968 and 1977 not much left of either. From my 1903a4 clone with criterion barrel im getting just under 2 moa.
The other HXP I have is closer to 4 moa. Forget testing with the mixed head stamp stuff from cmp you will struggle trying to group. The difference from year to year can be as much as a few inches from my experience. ahh already to go but no good secure bench or vise to hold the barrel vise...
MY END GOAL IS TO HAVE THE POTENTIALLY MOST ACCURATE M1 AND STILL BE WITHIN CMP AS ISSUED MATCH RULES. ITS UP TO YOU TO FIND OUT WHAT THOSE ARE. I WILL POST LINKS TO INFO I USED BUT DID NOT PERFORM ALL THE MODS. ONLY ONES THAT KEEP RIFLE LEGAL FOR AS ISSUED MATCHES.
cost thus far
M1 SG when they where 595$ or so
Orion7 g98 spring kit 28$
Barrel 184.95$ shipped
caswell stainless black 30$ shipped---- 2nd guessing this step, owell got to learn.
Stock Metal : ammogarand 57$
Stock set : DGR 207$ standard walnut fitted unfinished. Fitted to DGR house rifle. You can send in your rifle for custom fitting.
LINKS: I will add as I remember them and relocate them.
A good amount of info was found here

My best 1st hand info was gained by talking with the seasoned shooters at the range. Don't be shy.
POST 16 : TRIGGER done
POST 22 : Test Ammunition done
POST 24: Metal finish- gas cylinder done, stock metal in progress
POST 33,34 Wood--- in progress, 3/21/15 final fitting, butt plate and front hand guard needed some trimming. Rear hand guard needed just a touch of relief.
3/19/15 installed barrel, planing on reaming chamber next week.
