I have found the CCI subs are a pretty good replacement for the old Winchester subs I used to run too. Probably more accurate if anything. Haven’t tried the S&B though.
Just picked up a CZ 515 so will need to find out which ammo suits it.
I have a 1938 vintage Winchester Mod 61, just loves SK Long Range Match. Works pretty well on wallaby with night vision. They are solids, but seem to stay in the target.
G'day all,
in my Anschutz SK Subsonic HP at the best followed by E.ey Subsonic HP and RWS Subsonic HP
Off a Harris bipod at 50paces, SK better than 0.3", Eley about 0.3" and RWS about 0.375" for 5 shots
Its not really fussy so its sometimes best to try others.
FYI I helped a mate set up his CZ 22LR and the SK subbies and I shot a sub .2" group off a bipod and thought they might be worth a go in my rifle. they worked great but are now unavailble in Aus unless they start making them again.
Cheerio Ned
