The FX Smooth Twist barrels spin pellets so slow you could measure the twist in feet, I have seen spin rates from a .22 cal FX as slow as 1 turn in 13 feet.... Bob

BobThat is not correct Bob - FX Smooth Twist .22 cal twist rate is 1:16" according to Fred Axlesson himself.
If you want the best, most knowledgeable answer to your question, contact Nick at Nielsen Specialty Ammo and ask him what is the longest, heaviest swaged slug he has that will work in a 16" Crosman.... He is selling many weights of .22 cal from 21 gr. up.... and is just introducing .177 slugs, starting at 15.5 gr.... You can take whatever he tells you to the bank, IMO....
