Even if you do get a set of these, you'll still eventually have to open it all up and clean the drive cone, and all that **** anyway.
Save the 40quid and put it towards a second reloader, if you bust balls in your hopper, switch it over and clean the dirty one when you have 15 minutes!
Hybrid Technologies make great products! Just look at the Hybrid grips and the Hybrid Shocker but unless the price is brought down I dont think these shells will really take off in the mass market. Saying that I bet the American 'n00bs' will love them!
