My 24DL .22 WMR/.410 likes the old standard 40 gr. W/W hollowpoints best--it's my most accurate .22 WMR with those.
Unfortunately I have to use 28 or 30 gr "unleaded" ammo to hunt anywhere within 3 hours of where I live, and the old 24 HATES unleaded!
Fortunately my G2 carbine with MGM custom barrel likes it OK, well enough to shoot ground squirrels up to 75-80 yards reliably. Same with my "Win" (Miroku) 1885 Lowall. My old Win 61M pump REALLY HATES unleaded.
We have a pretty good supply of all .22 RF in SoCal now, at least enough for any hunting purposes.
