Accurate 4350

Wildernesshunter · April 28, 2017, 12:25 PM

Gang,

I hit four local shops yesterday hunting for H4350 and none had any in stock and none knew when they might get some.

Sportsman's Warehouse had some Accurate 4350, so after talking to their resident reloading expert, I purchased a pound. (I have had outstanding success with A2200 in my bolt action 7.62x39, but that is my only experience with Accurate Powders.)

Anyway, has anyone loaded A4350 for a .243 Win....with 95-115 Berger Bullets?

Looks like 60k psi is the max.... and the Accurate Loading Data shows 38.4 gr is the max for a 100gr Sierra SBT....getting just over 2,900 fps.

Currently I am shooting, with stability, the Berger 105 VLD. (9.125 twist at 6,200 feet elevation)

Suppose I should just work up some rounds for 36gr, 37gr, 38gr and maybe a 39gr and go see what they do. But if anyone has any personal knowledge....I am all ears.

Anyone have any experience with this powder????

Just for comparison.....The Hodgdon Website shows the following max loads:

H4350 - 37.5gr - 2,799 fps - 105gr H Amax - 49,500 CUP
IMR4350 - 40.2gr - 2,870 fps - 105 H Amax - 50,800 CUP

the difference between H4350 and the easter bunny is that some guys believe in the easter bunny. I"m nervous since I only have 18# of H4350 left. I'm gonna try IMR 4350 in the next few weeks but haven't yet.

Never used or tried AA 4350. I have 12lbs of H4350 and I treat that stuff like gold...

OP if you find published data for that powder in the cartridge and bullet of your choice go for it.

Check Accurate data for that powder and bullet.

If its safe load, then you can duplicate with a series of 3/10 below, spot on and above.

If its not then start lower and works up.

Only ever used IMR4350 for .243, but the AA has a slightly slower burn rate than the other two. No VLD Target bullets for hunting anything but varmints either.
A 115 is an odd weight for .243. You need the Berger data they want you to pay for by buying their manual because of that. There is a bit of now discontinued DTAC 115 grain data at the bottom here though.
