Don't know if they are still selling it since John Noveske's Death in a car accident last January....

but he marketed a 458 Noveske, a 284 case necked up...

sold them on used Model 600 or 660 Actions...

Hornady listed and made dies for them, Marked 458 Noveske..

seen one and shot one when I ran into John N over at the range one day...

oh, and it did kick a mite...but not as bad as when I use to run into Mike Bellm at the range, and he had me shoot a couple of his rebarreled Encores and Contenders....

the two hardest kickers were a 375 H & H, and a 416 Rigby, in a hand gun with 15 inch NON Ported Barrels.... thought it was funny, but each one was going to customers in Michigan that were planning on hunting deer in Michigan and taking them to Africa to hunt over there... NUTS!
