I have a 10/22 with a Dlask 16" .920 barrel. I have all of the aftermarket goodies in it with it all resting in a Barracuda stock. I haven't gotten many rounds through it since I added the Dlask barrel, as almost every other round FTE's so I ended up just putting it away and start shooting something else. Spent cases seem pretty tight in the chamber, and it did this with a wide variety of ammo, from Winchester, Federal bulk, to Eley, and SK, etc.. I have used both the Volquartsen and Power Custom extractors, and neither made any difference. How much spring tension is normally on a 10/22 extractor? Could this be the problem? I appreciate any input guys, thanks.
