Rechambering a ruger 45/70 1-S to 450 AK with a lapped bore and a .5 degree throat. Got Veral Smith of LBT makin me up a mold of his LFN design .390 grains with .2" contact ahead of the crimp groove.Bullets sized .4605. Moyer trigger for the number one. Vari x 111 1.5-5 X20 . Been playin with this cast thing a while. Anxious to see just how potent a cast gun can be. My lott throws 480 grs at over 2500 FPS but its a bit much in a ruger 77 to haul in dence bush. This mean little plick oughta be the real light weight barn stormer. If I get those 390's outta there at 2400+ somethin more than my shoulders gonna take a hurtin:D
 
Sounds nice, you may still find the heavier(480gr. cast) more accurate, I find them more accurate in my 45/70 heavy loads....Didn't know Veral Smith was out of jail and making moulds again.
 
Gun is on its way back from Wilcox gun works LTD. after chambering. Chris wilcox does everything from the 10$ job to the complete custom work. Known Chris a long time. High quality,low price...Just aching to get some brass blown out to 450 from 348
 
Beware of lead buildup at those velocities.
I've done a lot of casting. Loads above 2000fps have to be watched carefully.
Sometimes minor variations in the melt can result in heavy duty streaks down the bore, and/or bad accuracy due to gas cutting, blowby etc.
This lead build up can and will build up pressures over a long shooting session.
As to hunting with lead, go for it!
Nothing like taking game with your own bullets. The hard bullets you need for those velocities won't expand much. But big bores compensate for lack of expansion.
I've taken a number of whitetails with the 30-30, 303br, and 45-70 and cast loads at factory equivalent velocities with no issues.
Mostly I keep velocities in the 1800 to 2000 fps range now though. They are less finicky, tend to be more accurate out of my guns, and get the job done on game.
One cast load I made up for the 45-70 was so fast that it was too flat shooting for my rifles sights. I had to change front posts to use it. It leaded like a bugger though, and I dropped it years ago.

Marlin 45/70 shoots 459 WFN LBT 340gr at 2220 fps cleaned aprox 250 rounds ago. Still holds moa
Ruger 77 458 lott shoots .460 LFN LBT 475gr at 2590 fps cleaned aprox 40-50 rounds ago. Still holds 1 1/4 moa
If the alloy,lube,get the bore conditioned it becomes like a 22lr
