I had a tin of Crosman 10.5s that shot as well as H&N Baracudas in my P35-177. I shot exactly the same score (184 I think) on the 30 yard challenge with both pellets. So I bought more. The two new tins are MUCH worse. OK to dirty the barrel, maybe for plinking but certainly not for target shooting. I got curious so I bought a pellet gauge and checked the few pellets I had left from the old tin and the new tins. The "good" Crosman tin had head size similar to the H&N pellets and was about as consistent. The "bad" Crosman tins had head sizes covering the full range of openings in the pellet gauge. All over the place. No wonder they shoot poorly. I also found that H&N Match pellets were more consistent than H&N Baracuda or Baracuda Power pellets but their head size is not consistent with what it says on the tin. Still not sure which H&N pellets I want to stock up on but I know it isn't Crosmans. Might be the copper plated Power pellets. Their head size is not terribly consistent (but much better than the Crosmans) but they shoot really well. I have some sorted with consistent head size to test.
I also use Crosman 14.3s in my Prod sometimes but they do not shoot as well as H&N FTT copper plated. It does not like the unplated FTTs any better than the Crosmans but shoots the copper plated really well. I got that gun in 2020 so all the pellets have been purchased over the last couple years. P35-177 arrived in June of 2022. But I had the first tin of 10.5s for awhile.
