FX slug liners: Some FX slug liners want .217 and some want .218. The .218 seems to be a better choice for most liners from the feedback we have received.
Daysate: Daystate want .217 sized slugs.
Lothar Walther barrels seem to want .217 sized slugs in most guns.
These have been tested in Daystate factory barrels and M10 factory barrels with great success.
Warning: Last items in stock!
Other barrel testing coming. At this time, we do not expect these to work in original smooth twist FX barrels but should be OK in the new Slug X barrel by FX.
Do not buy these or any slug for standard smooth twist FX barrels.
These do work in Smooth Twist X barrel SLUG liners.
