A friend recently acquired a Hoyt relined Smith that, after being gauged, appears to have a bore size of .500.
Why so small? Is this the common size for a reline? And, what bullet and size would you guys recommend?

Hello:
Before the experts chime, is .500" the land or groove diameter, please?
Respectfully,
Kevin Tinny
The original Smith bore diameter is 0.50". Most are very close to this. Groove diameter runs 0.512" to 0.515". The repros generally have a tighter groove diameter. Bobby will do whatever you ask.
A .500 plug gauge will barely enter the bore from either end.
So... the rifling is .010 to .015 deep and a .515 smith bullet will not lead the barrel?

What size did you expect? It is not too small. Like any black powder gun, the lubricant, lead type and charge all can have an effect on leading.

Like Bruce Cobb Said.
Get a mold and a sizer for the Barrel.
Some folks I know have had the same issue with relined Maynards where the bullets need to be size to .515 or .516, I think guys shooting originals are around .518. I did but I am shooting a Romano and a Teammate shots that gun, very well in fact.
Don't try to size a bullet to large for it because you will loose the ability to put enough lube on it, The issue I almost have with mine, but it still works.
Also, I know few people that actually have a problem with leading if they size and lube their bullets properly.
THEN AGAIN: seeing who has already replied If I was you I would ignore my post... HA!

To revisit this.
If you use a .500" plug gauge to measure you measured the dia of the lands.
Only way to measure the groove would be to slug the barrel or have the cutter.
As you stated if you have .015" deep rifling your groove dia would be .015" + .500" + .015" to get to the true groove to groove dia. Being .530"
This is the reason I stated it is more likely you have a depth of .0075" or .015" overall
Most I have sluged or measures will take a .500" gauge plug and slug close to .515"
Being you want full contact, for a lead bullet norm is to go .001" to .002" over
That is why most shoot a .515" to .517" sized bullet.
My smith took a .500" plug as in this case. I shot an RCBS smith bullet mold sized at .520" with no leading.
It shot better with a .517" as normal loads.
