Need .223 data for Sierra 69 MK and H322

[YodaVader]

If anyone has a Sierra manual I am interested in .223 load data for the Sierra 69 grain MatchKing using H322 powder. H322 is one of 4 powders I have on hand for .223 use. I have data for the others but not H322. The load is for a 700 LTR with a 1 in 9" barrel. Any information would be greatly appreciated!

20.0 - 23.6.

if you email sierra and ask them, they will send you the sheet you need.

Not from the Sierra manual, but from hodgdon.com instead.
H322 23.0gr 2962fps 51,200 CUP

You may be able to increase your max a tenth of a grain or two since you're loading 69gr SMK.

As always, start low and work your way up to a suitable load.

Thank you for the replies! H322 was my main powder in my old 14" TC barrel with 52,53 grain bullets - excellent results. Got away from it when I went to a 26" barrel 700 VLS and started using 748.

Now I have the 20" 700 LTR and used some H322 yesterday with good results on the 52,53 grain bullets. Thought of trying some H322 loads with the heavier 69 MKs.

Again - many thanks!
