Hand loads for the M1

Good Afternoon gents, Ive got a CMP special that I would like to make match ammo for. I have an adjustable gas plug already and the rifle is running fine with no adverse affects when utilizing modern ammo. I haven't tried commercial 30-06 match ammo yet. But I digress, anyway what combination of propellant and bullet have you gents been lucky with? Thank you.

46 grains of IMR 4895 or 4064 and a 168 grain SMK.

Thanks from Doc and pitbulz21

I don't know what style of shooting you do with your rifle, Garand Match or just casual plinking, I will give you a few loadings that I have used in the past with good/exellent results. As for the adj gas plug or the vented plug I feel there a answer for a non-problem if you stick with medium burning powders at established velocities.

All case prep is the same, deprime and F/L resize your brass trim too 2.484
135 Sierra HPBT
47.5 IMR/H-4895
Primer- Win large rifle or Wolf large rifle
Coal- 3.22 too 3.25
Very peppy, and minimal recoil, yes your M1 will function, great load for use in the 200yd offhand and sitting rapids, takes almost all the recoil out of the 03 Springfield, if you use this load in a Garand Match your score will take a huge jump up just keep the load a secret and let everyone think your a STUD.

Any 168 HPBT
46.5 Varget
Same primer as above
Coal- 3.30
Nice mild match load, currently Hornady uses there 168 A-Max with this load for CMP Games, great load in the M1 or Springfield rifle.

Any 168 HPBT
46.5 IMR/H-4895
Same primer as above
Coal- 3.30
Clone load of LC Match M72 Ammo, everyone has fired this load at one time or another put simply it just plain works.

Any 168 HPBT
48.0 IMR/H-4064
Same primer as above
Coal- 3.30
Also a clone load of LC Match M72 ammo, you can swap out the 168 and sub in a 175 Sierra or 178 A-max and it will serve you well.

These are all mild loads and M1 safe for preasure the 30.06 has plenty of air space, you can play with the loads +/- .5grs if you wish, the target and the rifle won't know.

Thanks from DForington, cowpoke, Doc and 2 others

Hey folks,
I revived this thread as my questions are very similar to the OP, but I'm looking for more specifics.

So I just recently purchased a special grade, and I'm very excited to get some ammo down range and tune this thing up for deer hunting coming up real fast. That being said, I immediately purchased a Schuster gas plug after reading about the lighter pressures required in this platform. I 'm looking at creating a load rather than using commercial or mil-spec ammo. So, my questions:

1. Should I do the load development with the original gas plug, and than move to the adjustable, or just go with the adjustable and stick with that?
2. I will be using 165 gn. Sierra gameking HPBTs and IMR 4895. Looking at the data Phil suggested above, would I be safe starting at say 46.0 grains of powder and working up from there?

I do have a load manual from Hornady and have read through the M1 service rifle section, but my experience is the Hornady manual tends to be overly conservative.

Thanks in advance!

If you intend to use the adjustable gas plug then develop your loads with it installed. No use wasting ammo/time by changing the rifle components later.

Agreed. However I don't see the need for an adjustable gas plug or making the M1 shoot "hotter" than it was intended to. If you want a 1000-yard deer rifle just buy a nice bolt gun and a nice scope, and practice. 47ish grains of 4895 under an appropriate 165-168 hunting bullet will do the job just fine, for as far as you can shoot it accurately enough to hunt with it.

But it's your rifle and your money, so have fun.

As for your #2 question, I would personally start around 46 grains and not go higher than 47. Dollars to donuts you'll find an accurate load somewhere in there.

Thanks from TCAF, swagbrdr and Doc

Thanks Fellas!

So what I'm gathering is that load range for a 165-168 is safely usable with the original gas plug? I have no intention of making a hot rod M1 by any means. I just bought the adjustable as insurance against over-gassing. I know the match guys have used those in the past to change barrel harmonics...but, a side benefit is the ability to cool down an over gassed rifle.

As far as bolt guns go, I have plenty of them that shoot quite well. I just wanted to try something different this year.

I'm kind of a big dummy, I fail too see how a vented gas plug helps with the harmonic issue....Harmonic/vibration/frequency starts with primer ignition and rolls forward like a wave. It is every shooters desire too have there bullet ahead of this harmonic node for best accuracy. A vented G/C/P may help cushion the op-rod and feel softer recoiling but I don't see any harmonic reduction, but that's me....

Anyway, the loads listed should work well regardless of what gas plug you run in your rifle. There just clone loads or loads that have served many others well. Give them a try, diddle them up and down too your harts content.

It depends on the rifle, but I personally have found that IMR 4064 gives better accuracy with 175 grain Sierra bullets than IMR 4895. For 168 grain bullets, either Hornady or Sierra, IMR 4895 does just fine. With either bullet, I am using Winchester brass and Winchester large rifle primers. The 168's are pushing an average muzzle velocity of 2600 FPS and the 175's are at approximately 2650 FPS on average; these were obtained using a chronograph to determine what shot the best.

My M 1 special loves BTHP Hornady 168 grain with 46. Gr of 4064. It will stay in the 9 and 10 rings all day long on a 200 yard high-power course.

You have been given good advice in the threads above - stay in those ranges for loads...
And, I agree with other posters, I see no need for the vented gas plug - stick with the powders and loads listed above. As stated, if you want a earzen-spliten-loud-n-boomer for long range shooting - get a good bolt gun.
As for harmonic nodes - don't sweat them. The speed of sound in steel is approximately 17000 feet per second, depending, so there is no way the bullet beats the vibration waves down the barrel. Just pick a load within the ranges listed above and get butt deep in brass.

doc,as far as the vented gas plug.my thoughts on them are find a setup with it that functions with hunting type off the shelf ammo.you can stuff it in the buttstock or range bag.when no m2 ball spec type ammo is available,you can pop it in and save the op rod.

How are you M1 match reloaders liking Varget with any of the 168gn to 178gn match bullets? Phil mentioned one Varget load in post #3 above. Not a reloading expert myself, but I've read that 4064 and Varget are pretty close load-wise.

I'm asking because I'm hugely stock-up on Varget. Thanks!

It will work as well as any of the 4895's or 4064, just depends on your rifle. Hornady has used it in their 168 grain amax load for the M1. I've always heard that varget is almost like a short cut, temp stable, version of 4064. For some reason 4064 meters better for me than varget. I've got maybe a pound of varget left for loading the occasional hunting round. I agree with others that an adjustable gas plug isn't needed. A waste of money if loading your own.
