Gene, the Tomahawks were shaken, not stirred in shipping, so there are a lot of ruined pells in the tin. I've had to pick the best of the lot out and go with them. Maybe I just don't like the look of the tips, after the predators were used. They don't shoot any better or worse than the preds either, at close range.
My top 3 favorites are the superdomes, exacts, then hunters (long range pells). The preds are wicked at close range (my favorite takedown pell), as are the crow magnums.
I like the skirt-in-a-skirt design of the .22 superdomes. Almost like they wedged a .177 skirt into the .22 skirt for more weight.
I use more Crosman Premier HPs than anything else, because that darned CX4 just gulps a 500 ct. tin in no time...BUMMER!
Keep 4 30 round magazines loaded for it when plinking, and never have any less than 3 extra 88G bottles in the case at one time.
I've found-out one thing; it takes a lot of time to target/chrony multiple rifles and pistols, to see which shines the best in each gun.
I took note about the changes over time you mentioned. Will be interesting to test again in about a year.
