I shoot a .308 Rock River LAR BT3 with an 18” barrel. I attached a Yankee Hill Machine Resonator R2. Noticed accuracy issues. Took it to a gunsmith for advice and was told to run 5 rounds through it cold, then 5 rounds warming up the can and then 5 more with the can hot all at 100yrd. The first 5 rounds had 4 inside an inch with 1 flyer. Each shot about 5-10 minutes apart with enough time for the can to become cool to the touch.
The next 5 for warm up produced a 5 inch group.
Then a reload
The 5 rounds hot ended up inside an inch with another round slightly outside the 1 inch group. but the grouping migrated up from the cold rounds about 1-1.5 mils.
Is this normal suppressor behavior?
