Im trying to find hollow point pellets in 4.52mm. (H&N, please read this, i want Baracuda Hunter or Hunter Extreme in 4.52 ) My S510 loves domed 4.52 pellets (JSB, AA and H&N, its all gooood)
I tried some 4.52 Match S100 Heavy Weight (8.26grain) pellets yesterday, no good at 30 yards. I will try some from the other two tins I got, but I'm not very hopeful.
