when it comes to inlines, blackhorn209 only! I'd say lewis had an issue with the knight breech set up in general. I can load up a powerbelt or thor, seat the projectile with 2 thumbs over the end of the ramrod and she goes bang every single time. This is with a CVA/Traditions. Even my Winchester X-150 will shoot it reliably with the hex head (enclosed) cva breech plug without a hitch.

My brother in laws new mexico buck from last week. 110gr bh209. barnes tmz 245gr, federal 209a primer. 201 yard shot.
