260 AI -Looking for load data

[rbeckwith]

Anyone care to share thier experience loading for a 260AI? My barrel is a 9-twist, so I am shooting 120 gr. A-max or potentially 130 Gr. VLDs. Any informmation would be appreciated.

I know in a standard 260 H4350 powder is widely used. I run 42.5 in mine with a 140 or 142. You will probably be 3 or 4 grains more capacity, you can make that 120 scream. But that powder will most likely work very good.

Used to shoot the 139 Scenars with 4831sc. I want to say I was pushing it around 2950. Powder charge was high 47's to 48's depending on the brass I fire formed. A real barrel burner of a round if you want it to be. Good luck

I just happen to have a few lbs of 4831sc...I think I will give that a try.

Thanks, Gentlemen.

Wha primers are you using? I have been running Fed 210m but have been told to try WLR's or even the Fed 215m.

Any thoughts on either one of those?

Just to update anyone who read this. I was able to get very consistent velocity and great groups with 47.1 grains of H4831sc, 120 Grain A-Max, Lapua 308 brass necked downed and turned with a 210M lighting the candle.

Not that anyone cares...but I need 100 posts so I can sell some shit.
