If you strike out on finding a bells and whistles reamer .
Fractional chucking reamers are very affordable and for 45 close enough for my use .
A 29/64th = .4531 and cast bullets love it.
A cut off 45 colt cartridge fits snug over the reamer and acts like a pilot of sorts, from the chamber side .
Take it slow and very easy to run in straight as it is cutting so little .
I also use a 5/16th equaling .3125 for my hotrod 32s.
In a good machine shop supply, you should be able to get fractional sized reamers for 20 to 30 bucks.
Decimal sized run a lot more but have in between sizes.
