I am using A-4350 in my Custom Mosin .308 Open rifle , and have been for five years now . I ran comparison tests on all three 4350 powders out of my Mosin , equipped with a Krieger 5r , 30" 1-10T and the A-4350 not only had a consistent higher velocity , it was also more consistent in SD , and on the target , where it really counts most . Ask yourself who made the "Burn-rate" chart , and why the "H" & "I" powders rated better . That doesn't match my data for over 12,000 rounds of competition shooting , through Krieger , Brux , and Bartlein barrels . I'll keep using the A-4350 as long as I can get it , and it stays at the quality level it is currently at . Use whatever works best in your rifle . Regardless of the "Brand" name .
To the OP : When asking for advice on a powder , it is always helpful to members to know the rifle caliber , bullet being used , and even the brass being loaded . We can give much more accurate and concise responses that way . Thanks .

PLEASE check your lot numbers. I wound up having about 30 lbs of the recalled powder in AA2495. I hadn’t used it years but was planning on going back to it for 6BR to conserve some other powders. The below discussion is scary - who knows if the recalled powder was the cause, but the result is bad enough not to risk it.
6CM Case separation new brass (near fatal).
I had an accident Feb 2020 where my rifle blew up. Today I still have not determined the cause. Of course covid has delayed and delayed my search for the cause. I love to shoot club matches but nothing more competitive. I am retire military veteran and at 76 I would hate to give up a sport I...

Yes I just bought this powder today from Midsouth. I would think it's OK? It won't be here for a week or so.

I just got a pair of 8# jugs of a different powder from them that were 2015 lots. He should check those lot numbers.WD
ShootersWorld 4350 is the slowest of them all and not listed.
Yes, it is very much slower burning than the other 4350s. This is Czech Lovex SO-70 that was sold in the US as Accurate Arms - 4350 until 19 years ago. (Today's Accurate-4350 is made by General Dynamics in Quebec Province, Canada in the plant that makes IMR powders for Hodgdon.)
I tried SO-70 / SW4350 last year in a 7mm-08 as part of a 14 powder test series looking at possible UK alternatives to IMR/H4350/H414 which are no longer imported here due to health & safety regulatory changes. The load was large primer Lapua, Russian primer, 160gn Sierra TMK seated for a long-throat match chamber.
I could get nowhere near H4350 MVs despite what QuickLOAD computed and / or the old Accurate Arms quoted for its nearest equivalent maximum load. 46gn SO-70, a full-case charge, was nigh on 200 fps down on where it should have been and well, well down on H4350's 45.0gn performance. This was from a recent manufacturing lot. I was so surprised. I had to check that I hadn't loaded SO-71 (the old Accurate Arms - 3100) by mistake because MVs were about what I'd have expected from this powder. Spreads and groups were very good over a wide charge range, but way, way too slow. I half wonder if Explosia had mis-labelled this lot of some slower burning grade as the powder wasn't nearly as slow burning as this in the past.
