I have one ,and I like it a lot,
so far I only shot factory ammo and avoid lead bullets,
Got some sierra bullets 250 gr JHC but dont have any dies yet ,I have a dillon square deal B and they make the conversion for 45 colt but will not work for the 454.
Factory ammo is expensive, didnt get to shoot a deer this year with it.
As far as recoil, get you some good shooting gloves,It hurts with the 300 gr bullets from hornady.
This is a hand cannon and if it rolls in your hand it will peel the skin
I had to use a wood dowel rod to extract the hornady cases,
I emailed hornady about it and their reply was that brass would be ok for reload.
Did not have that problem with magtech or winchester loads.
