Just got back--conditions were actually quite good for winter in Maine--50 degrees and very humid. Here's what I got for the last 8 130 corelokt cartridges I had out of my ruger American with 22" barrel. No ways near as good as the Hornady or Winchester ammo, though I'd probably shoot it "minute of deer" out to 150 yds or so, but I personally wouldn't use it much past that with confidence.
