Thread: Shortening a CZ455 varmint barrel - how short to go?

Giving it a really thorough clean seems to have sorted the supersonic subs issue - at least back to how it used to be.
Now I just need to get enough rounds through it to close the grouping up again.

I think I will grab a box of the CCI 40gr Quiet Segmented rounds to try. No chance of a supersonic round, and probably ok for rabbits at less than 100M. Time will tell.
