    I have an Impact that I've converted to .22 cal with a 700 MM barrel that I acquired from a friend.  It has an STX barrel, but initial results with slugs is dismal.  Which barrel liner works best in your 700 mm barrel?  I want to shoot 25.4 gr JSB KO slugs or something similar.  I'm thinking that the superior liner is the one to choose.  What's your experience?

    jps, I have a 700 mm .22 Impact, and I bought a slug A liner for it. Couldn't make it perform. But with the STX pellet liner I'm getting good (half inch at 70 yd) accuracy with H&N .218 23 grain slugs at 885-895 fps. I haven't tried any other slugs in my pellet liner yet.

    I have the slug A and for me it shoots lights out.  Shoots pellets and a multitude of slugs very well.  I polished it with JB bore polish and used their bore bright as well.  Don't know if that helped but I have the stuff and always do my barrels.

    Nielsen 23gr may be worth trying…

    same here, my 700mm slug-a liner does very well with nicks 24.8gr dbhp slugs right at 1012fps.

    i just thought that h&n and fx slugs did good……nope !!

    It appears that all FX offers now are Superior and Heavy Superior barrels.  Is that true?

    Yeah I think those liners made the slug liners obsolete.  Which is a shame IMO, my .22 and .30 slug liners are fantastic the .25 isnt quite as good.

    Couldn’t agree more. Recently got a brand new Impact .22 and had an unused 600mm slug A liner that I bought more than a year ago for a Crown project that never happened. Got my harmonic tune done this weekend (took three weekends and a 1000 slugs) and shot no less than 10 sub 20mm c-t-c groups at 100m.

    So beautifully consistent. Could not wish for more.
