Ebay seller for pellets. Any good?

Yes they are. I have shot a lot of his .22 fp and hollow point. I shot both of them with an open reticle, not a scope, and still cover 5 with a nickel at 45 yards. I use an open reticle for varmints around my house and it's faster acquisition time. The hp opened to nearly 1/2 inch in a water jug at 58 ft lbs. 
I shoot mainly his heavy pellet and bbt hp in my 357 and it's one ragged hole at 65 yards, I've not shot it further than that. I've shot several others that were accurate but for my ace I keep it around 100 grains or below because it is stock and not modified. I like that he puts sample packs together.. it helped me choose what was best for my gun.
