Going PD hunting and need to hand load 500rnds+ 223 ammo. At Sportsmens Warehouse they had HBR ammo 400 rounds of 223 Lake city brass 60 gr V-Max bullet for $179 . Posted velocity of 3035 out of 24" bbl. Always curious to what weight of powder charge of factory ammo. So I pulled a bullet and it contained 22grs of some type of ball powder. Called up HBR today and asked if they stand by their velocity reports they said yes,but connected me to ballistics tech. He wasn't around so i left message and they said he always returns calls . Told clerk at gun counter ,he said " They have their own blend of powder " Well going out tonight to shoot a few rounds through a chronograph . So any one have any predictions out of 20" AR-15 ? I think I'll be lucking if I get 2800 FPS . Oh I read reviews on this ammo before purchasing and 5 stars for 5 reviews stating under MOA at 100yards .
