I had a bit of fun with my 22 insert but as I reloaded for the 455 using shortened 45 Long Colt cases with the rims turned a bit thinner, I preferred shooting the large calibre more and it was cheap loading with 250gr cast bullets and a bit of Unique powder. Cases lasted for ever so only needed a 100 turned up on the lathe. Sold off the 22 insert to a guy with a 6" barreled Webley after I had played around with it for a while.

I like your website - shot buffs on the Finnis River Station back in '78 with my 404 Jeffery - out with a pet meat shooter for a week so got to bowl a few over including a reasonable bull or two. Used a mix of Kynoch SP, Parker Hale FMJ and my own RWS FMJ reloads. Can't fault the 404J on the big boys.
