Hello all,
I purchased some 150 gr SST's and Hodgdon H322 powder (1lb) today. I am wondering if it would okay to use with the m14? I have a load idea of 39.00gr under the 150gr sst with a COAL of 7.770.
Thoughts?

Do you know what the volume of your cases are? If not, then what brand case?

In general H322 will work pressure-wise but I don't know how the accuracy will work out. I've used H322 with 130gr TTSX bullets and 110gr Hornady Vmax bullets. It worked reliably but my groups were not the best I've ever gotten.

I also have some H4895 powder on hand.

H4895 is much better but you can use H322.

Hodgdon data assumes Winchester brass, with Norma, FC, LC take a grain or so off the max.

I would not use the SST bullet unless you are specifically after a hunting load. Get some nosler 155s in a bulk pack for 600 yards or less for a target load they are the best deal going.

sadly I am up here in Canada & Noslers even in bulk are premium priced.. think $45/100 minimum :(

The original 322 was made by IMR for 5.56 development. Only it was called 8208 by Remington. When the Army made the decision to load 5.56 with ball powder, the 8208 was eventually put on the surplus market.

Thunderbird Cartridge Company sold this surplus powder and called it T322....benchrest shooters loved it because of its accuracy. Because it was cheap, I bought 8 or 9 of the 8 pound T322 jugs and used it over the years. I loaded 38 grains under Sierra 168 MKs in LC cases for my M-1a and it was a super powder and super accurate out to 300 yards.

Benchrest shooters loved it so much, that Hodgdon had a new batch made and called it H322. It's still going strong today.

So the H322 is very similar to the old T322...but not identical. I would start at 38 grains of H322 with a 168 and slowly work up to your best load. With a 150 grain tip, start with 39 grains and work up. I think it will be a great short range (300~400yds) powder for your M-1A.
