Just traded for a TC Renegade barrel that was rebored by Mr Hoyt. He didn't mark it that I can find. It was represented to be 58 caliber, I'm getting. .603 across the grooves, anyone know if this is normal for his rebores?

Across the grooves is not how we measure bore. We measure from land to land.
Some do go by groove to groove, didn't know about Mr Hoyt.
Land to land is .588 , rear sight mounting hole is professionally plugged. Just wondering if this is a custom job or standard.

I had a Seneca .36 that Bob Hoyt re-bored to a .40 with a faster twist rate. I had to size my bullets at .397 for it.
I just acquired a .50 TC New Englander that Bob did a .45 barrel liner in. That is a very tight bore as well, having to size bullets to .4475-.448
Are you running bare balls? .440 is standard size for .45
I’ve never met anyone in the muzzleloading community that uses groove to groove measurements. Land to land is the bore size, even on modern stuff.
There is a whole world apart from muzzleloading, especially in other parts of the world that have had firearms long before there was a United States
These are custom bored and rifled barrels, thus they are not constrained by an industrial standard. That is why I am asking about what is normal for a Bob Hoyt .58 bore.
That is not what we are discussing here. In fact, discussing non-muzzleloaders is not permitted here. So, nice try at splitting hairs.
You still go off land size, not groove size.
Maybe you should do a little research on the subject, and butt out of my post if you don't own a B Hoyt rifled barrel.
Perhaps you should be an adult and accept facts. You got your answer in the first response, but you can’t accept it because you can’t handle it. Land to land is the bore size in 99% of all firearms.

Groove depths vary depending on cutter wear, but land-to-land should be more consistent.
Even land-to-land calibers vary depending on the reamer diameter. There is no guaranteed bore size in custom ML barrels. Just use a thicker patch.

With a traditional muzzleloader you check the caliber with a precision plug gauge, not the depth of the lands. Question for you, ever wonder why some 44 caliber guns use .429”/.430” bullets and some 45 caliber guns use .451”/.452” bullets? Yep, there are ‘standards’ for gun calibers….
I own a number of Bobby Hoyt rebores in 58 caliber (so I guess I can comment), a couple with radius bottom rifling about .015” deep and one with .010” deep square rifling. I’ve got one 50 Caliber gun that he refreshed for me that now has a .510” bore with .012” deep grooves, yet shoots .495” or .500” diameter patched roundballs.
Ok, now it’s your turn to show us your research on why the previous posters in the topic are incorrect, although, until I see your research I am agreeing with them, no disrespect intended or meant.
Mr Hoyt doesn’t mark his rebored barrels. I have always put the new information on the bottom flat of the barrels he rebored plus I remove or defarb any old information on the top flats. Makes it easier in the future when all the history on the barrel is forgotten, at least for me.
Thank you, it's the information I was wanting. As far as the whole groove and land thing, it is irrelevant to me, I only was curious if that was the way Mr Hoyt normally cut them. As far as my research, it started a long time ago when I was a Tank gunner in West Germany. I went to several museums and castles, talked weapons with old timers, and attended a few Jager shoots. It coninued as I went on to be a Light Weapons Specialist in the Airmobile Infantry in various foreign places. After 28 years in the military, I worked in State Law Enforcement, and always talked to the old timers about guns. I'm no expert but I have been burning powder for 65 years.With a traditional muzzleloader you checked the caliber with a precision plug gauge, not the depth of the lands.

No, I don’t shoot any PRB’s. Never been interested in that . My sidelocks have all been custom barrels or re-bores or liners with fast twists so I can shoot conicals or modern jacketed bullets, even sabots.
