“Was using the CCI Quiet rounds in suppressed 10/22. Gun wouldn’t cycle and groups were 1.5-2” at 25 yds. Ordered some of these 45gr rds and DANG. The rifle has cycled with no failures in 150 rounds. And the accuracy is outstanding. Grouping down to .5”. I can cover the hole made by five rounds with a dime. They are just a touch louder than the 40grain quiet rounds. Highly recommend for shooting suppressed.”
