I know for a fact that no matter how accurate a barrel is, it gets better performance from a CF sleeve.My own rifle and my friends went from about 1/2" groups at 35yds, to sub 1/16" with the sleeve at the same distance.Now the caveat is, it wont fix a horrible barrel, but will fine tune a good one.
When baking the sleeve and barrel, does it stink bad? Not at all? Thanks,
Looks good! From a bench obviously.
Do you have any group pictures from before you sleeved for comparison?My 177 Marauder only likes AA 10.34 grain pellets.Crosman Marauder 177 and 22 barrels are just too big ID for most pellets - and only if they get the choke just perfect will it like some pellet.Ray
Were those groups from 50 feet as well?If so, the new groups do seem tighter.Ray
