As soon as I have some extra $$$ I'll get some 4350. Right now all my money is going into my Astro van trying to get the front end from shaking when applying the brakes. Before anyone says anything, I've already replaced the rotors twice and the brake pads and bearings once with no luck at all. I'm stumped to what is making it shaked like it's a warped rotor.

Sierra 174s and H4350 is one of the hest combinations for this case. Start at 52gr and work up. Most fond an excelent node at 54gr. This is PPu brass data. If your trying out the excelent Lapua 7.62x53r then start at 51gr.
Anealing with PPU is a must after 5 reloads. The Lapua stuff can go much longer.

All this talk is making me want to dig out the M28/76 again.
What OAL did you use with the Sierra's?
OK, just came back from Sportsman's Warehouse with a pound of Accurate 4350. They had some 8ld'ers but I thought I'd try some out before buying so much just in case it doesn't work for me. Also looked for some Sierra 174's MatchKing but they didn't have any so I guess I can try the Hornady 174's #3131

I use 2.95 OAL. I use the same loads in all my Mosins and my PSL's.
Also the SMK and the Hornady bullet you have are very similar.
Midway has the SMK's in stock.
About the only difference I see in them is-
HPBT vs FMJ
No cannelure vs Cannelure
And the SMK has better BC
Firing from a iron sighted Mosin I don't think you would ever know the difference.
All 4350s are not the same but I have found that Accurate and IMR are very close in fact I use them the same in some of my loads. The
Accurate manual list 51 grs AA4350 as a max load with 180 gr .311 bullets. I find that 50 grs gives the best accuracy for me. I can't remember which manual it was in, maybe Lyman, but 52 grs IMR 4350 was listed as max.

Maybe for the 80gr but nothing for the 74gr in Hornady, Lyman, Sierra or Speer. I haven't looked in the Nosler book yet.
I'll just start low and work up with what you guys gave me and see what happens but it won't be for at least another week, the temps are going to be in the 114° most of this upcoming week and I fear the bullets would just melt mid-air if I shot them!!!!

It depends on the reamer used. Some I have an OAL of 3.25 and some 2.85. Do you know how to find your lands?
Every rifle is different. I always find the lands for each rifle.
When Tzar Nikolai counts out 3 arshins and 5 bubliki.
Or when your accuracy starts to go south without any other changes.
Oh no, not again. Every time I start talking about this I get mixed up thinking it's the ogive but yes, I do know how to find the lands.
