If you can find someone to send you a few to try, you may find that the 0.217/0.219 version may work fine in the LW barrel…. Slugs are generally sized to the choke, or 0.001″ under the groove diameter there…. I know some have had success going that route…. Ask Wayne52 on the GTA if he can spare some….
I have a non choked LW.22 that I just turned down for slugs.Its slugging out at .221!Even without the choke it stacks pellets.Have tryed the piledrivers threw it and got decent accuracy but want a good HP slug.I will give him a shout.Just dont want to throw $130 at a mold that may not be a accurate round.Thank you
