What do you consider a tight throat to be on a .460? I just got a new 8 & 3/8" model and a .452 minus gauge is a very tight fit in each hole. .453 won't go into any of the holes. I'm assuming this is a good size and hopefully will be able to get some good groups with .452 lead bullets traveling around 1500 FPS.
I would consider you to have normal throat and should not have any issues with published load data form Hornady or Barnes.
I have not had any leading issue with throats like yours using cast bullets sized .452 or .453 though typically I used gas checked bullets as I drive them at 460 velocities.
While I have built reduced load with cast and non gas checked bullets, the only time I encountered is was use correctly sized bullets but the were exceptionally hard. The lesson is the bullet has to seal properly.
The lube has also been a problem for some 460 reloaders- dont use a hard lube in my opinion.
Just starting playing with coated bullets so don't have enough experience to make an informed opinion but so far it looks promising.
be safe
