I recently built from the ground up a new 6 digit Springer with a new in wrap '52 dated Springer barrel (CMP about 5 years ago). The idea was to produce a 60's era-ish rebuild rifle. A like new birch stock with square proof stamp, and like new or new components in mostly zinc parkerized finish were collected over a couple of seasons to complete the project. To date the rifle has had about 175 rounds through it.
As powders are difficult to find for reloading, especially your "go to" favorites. I, again, had to work up a new load with IMR4064. Todays job was to work up to a favorite with 168gr HPBT and said powder. I used the same specs as previous match M1 loads:
HXP brass, trimmed, chamfered, primer channel reamed and pocket cleaned.
Sized: 2.033-35"
WLR primer
168gr HPBT
COAL: 3.30"

IMR4064 Powder tests: 45.5,46,46.5,47,47.5,48 grains
this morning 0800 calm winds, 100 yards, 75 degrees

and for the ever popular pictures...







Strangely enough 48 gr. was exactly what I found in an American Rifleman article from 3/86. That group measured a hair under 1.5 MOA/100yds.
It was a good way to spend the morning GI6

M1:
46.0 gr IMR4895 gives me very good results with less powder with a 168.
47.0 gr IMR4895 with a 155.

M1903a3: +0.5 gr powder

All in HXP brass, CCI 34 primer and 3.30-3.34" OAL.

Nice shooting.

Sub the projo's with 135SMK's and there's zip for recoil........ Great load for the Games.

Same here. I was pushing 125 TNTs with 49.0 gr IMR4895 and still my groups were rather poor.

I've never been able to get the lighter bullets to shoot well. I traded my 125s away for 155 Nosler CCs.

Thanks fellas, I can't get away from the steel and wood rifles. I especially like the birch stocked, zinc finished look with M1s. I had a Toole Arsenal refinished M1 configured the same that I sold years ago and always wanted to have one again. Other than taking a little creep out of the trigger it's all stock, didn't even peen the barrel (had to use a mallet to tap the GC on)
As far as the loads went, I knew 47-48gr would be a good combo but the Hornady M1 load data started & maxed out lower. After a little searching around to see what others were using I came up with that load range spread.
It's all fun
