M1 Garand

Post by gunny0629 » Tue Feb 23, 2016 5:48 pm

I went back a few pages before I posted this. I am looking for a safe load to run in my Garand. I am currently using H4895 at 46 grains and is getting roughly 2600 fps, but I am seeing on other forums that IMR 4895 is a better choice. Any comments or data pertaining to IMR or should I stick with what I have?

Copied this off the net years ago. When I reloaded for the Garand, I used IMR4895. Got fantastic results using military cases, 46 grains and 147gr FMJ bullets I purchased from Wideners. Those were the days!

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.

Only powder I use in M-1 loads is IMR4895. Only powder I use in any of my 30.06 loads anymore.

Same here.
As I remember, it is all about speed of the powder. If the powered is too slow, you may get a build-up of pressure during the firing that may bend the op-rod, too fast is bad as well. So as long as the speed of the powder is in the same general area of IMR 4895, it is okay.

According to IMR, power speeds are like this.

83 Ramshot X-Terminator
84 Accurate Arms 2230
85 Accurate Arms 2460s
86 IMR Co IMR 8208 XBR

89 VihtaVuori N530

Master Po has the recipe I use.
Winchester Large Rifle Primers work well.

I load Hodgdon H-380 for my M1's. It has been used to load USGI ammo. It's a ball powder and meters very well.

If you check the loading tables it gives high velocity and some of the lowest pressures.

IMR 4895 was actually invented (from 4831) for the M1 Garrand as 4831 was too slow and bent the op rods

Whatever you used to do using either H4895 or IMR4895 one must treat them as a new different powder until proven otherwise.
Winchester, Hogdon and IMR are now the same company and all powders should be retested when you get new cans as things are a little different some more so.
There is a difference between H4895 and IMR 4895, they are not the same as IMR comes out of Canada and Hogdon from Australia
It used to be H4895 was a tad slower and I believe that still holds true

I would personally not use H380 in a Garrand as that is closer to 4831 burn rates than 4895 but if it works for you great.

If one wants a ball powder for better metering (If one uses a Dillon a good idea) Accurate 2520 is supposed to be a ball equivalent to 4895. One might also consider AA2460 or H-BL-C-2 or its military surplus (If you can still find any)WC-846

All suggestions are worth what you paid me to post them [smilie=pdt_xtremez_13.gif]

Thanks for all the help. I am going to the range tomorrow and test out the IMR/H 4895. I have a buddy who said I should try out Varget since I have a lot on hand (to load my AR 15). For now I think I will stay with the two above.

Well it was used to load USGI ammo so it should be good for your reloads. [smilie=cheers1.gif]

Varget will work fine. That is about all I use in M-14's.

Another vote for 168SMKs and Varget. Like others I use Varget in several different calibers, but it works really well for me in .30-06 loads.

Another vote for Varget, the most versatile powder you can have on your shelf. I have though converted to IMR3031 for 30 cal light bullets (under 125 grains). We have ran 500 or so through my RFB and my sons Armilite AR10 with exceptional results. The 125 BT Noslers are beasts and I will feel completely confident taking shots on deer out to 400 with a good rest. The couple of 115 JHP's rounds we got through the crono before my son sort of shot it with a lead fouled 45 were doing just under 3K out of the AR10 16" barrel. Didn't get to get the speed on the Noslers but he just sent me a pic of his repair (plasty weld is some amazing stuff). In the RFB the 3031 with the BT bullets makes the rifle run the most reliable and accurate.
