I came across this deal last night and I haven't found anything better yet (
even with coupons and everything).
CCI Blazer and/or CCI Minimags are usually listed as recommended ammunition
for many .22LR pistols, which tend to be very finicky with ammo. Whether
you want to break in that new .22 or just use ammo that it will like, this
is a good choice and is relatively cheap.
