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.
Based on testing results it seems any of our HP .250 slugs can be tuned for FX slug liners. Some guns may like one weight better than another. Testing so far has been with the 33.5, 36.2 and 38.5 grain. 38.5 grain is heaviest we recommend to fit the FX magazine.
Do not buy these or any slug for standard smooth twist FX barrels.
These do work in Smooth Twist X barrel SLUG liners.
