Thread: WTB: Kilwell Whisper 37.5gr .22lr Subs

They were made by Winchester for killwell, but were 37.5gr instead of 40gr which is the standard Winchester sub, so they had Winchester cases but lighter projectiles.

I have never seen 37.5 win subs but I too may be wrong!

Unfortunately my CZ hates the 40gr but will put 10 of the 37.5gr through one ragged hole at 50m, I actually used them for f class at deerstalkers club shoots, was great as i didn't have to change ammo for small game.
Now I use cci standard for target and cci subs for hunting but neither is as accurate as the killwell was and they shoot to different poi so have to rezero all the time!
