Just saw them why looking threw a cabelas magazine. They are called aerolites, they look interesting. They are making a 250 and 300g bullet. They look to be about 2.00 each. I am not a fan of powerbelts but like the design on these new ones. A nice sharp ballistic tip, where the old ones are more flat and round. The bullet looks to be a little smaller taper from the nose to the base. If I wasn't trying the tezs this year, I would consider trying them. Hard to beat the tmzs.
