Greetings Kelton,
I chronographed some test loads with 165 grain Hornady Interlok projectiles using 43 grains of AR2206, AR2206H, Dupont IMR4064 and AR2208. They delivered 2,585, 2,575, 2,445 and 2,425 fps respectively. The rifle had a 20 inch barrel and a DPT suppressor. The AR2206 and AR2206H loads would have been near max from the Hodgdons Data. All were accurate. The AR2206 and AR2206H loads were as predicted from the Hodgdon Data allowing for barrel length and The last two slower.
Regards Grandpamac.
