Wandered over to Walmart (Danvers, MA) yesterday and they had 500-count tins of CPHP in .177 for $5.28/tin which is as good a price as I've seen. Picked up 8 tins. They are listed at $5.99/tin online, so check your local store and they might be less expensive!
WM has Crosman 10.5gr domed for $8 online. Not great but better than usual.
The Crosman hollow point design is really just a marketing gimmick. The dimple is too small and the alloy is too hard to mushroom effectively. This can be observed on pellets recovered from game, even when delivered at high velocity. They behave very much like a dome, both ballistically and terminally.
True, the Piranhas don’t have a very good reputation for accuracy. Much better to have an accurate dome to icepick a hole in the right place than a gimmicky pellet that misses the mark.
