Fx Impact .30 700mm slug liner ?

many places have both a pellet and slug liner listed for FX Impact 700 mm .30. I think the slug is suppose to have a faster twist rate (my be other differences FX considers secret ). I think the factory only puts pellet liners in new rifle though some retailers will swap them out?

As far as I know in .30 so far theres Pellet A liner and Slug A in 700.

at one time they had .30 700 pellet liner A and B listed and the .30 700 mm slug was released middle to late 2019. I don't know if both 700 .30 A and B pellet liners are still made?

I wouldn't bother, the .30 pellet liner shots NIELSEN slugs extremely well!

Actually the .30 cal never had a pellet liner B. Only the .22 (for the 26.4 monster redesigned) and the .25 (for the King Heavies). Since then the Liner B's have been discontinued as we have found the Slug Liners shoot these heavier aforementioned pellets just as well if not better, so thus the Liner B is no longer needed.

I cant think of a better source to be corrected by.
