i got a 200 pack of UMV 45gr hollow points to shoot up. i bought the gun for a lot of cheap plinking. the groups i got where about 2 inches at a 100yds. anybody out there have thoughts or experience with ammo to tighten that group up and narrowing down all the types ill have to buy tp try? thanks

sorry that was UMC ammo by remington

Also available: Winchester USA 45gr hp...40 or 50 pack. Does well (<1") in my two 223's.
UMC also makes a 50gr hp, as another option.

Try Black Hills re-man with the 52 gr match bullet .

Two .223s shoot the ( South African)PMP 55gr. sp very accurately { sub moa} roger
