Loads for 58 cal "Reneboar"

exPAtriate · Apr 19, 2024

Hello friends,

I just sent a not so great 50 cal. Renegade bbl off to Bobby Hoyt to be rebored to 58 Al with a slow twist for prb. Any ideas where to start with powder loads?

I'm kinda excited about this one!

Look at the 24 gauge loads suggested here.

My Bobby Hoyt re-bored .58s have a 1:70 twist and like heavy loads to get the best accuracy. The flinter seems to like 95 grains, and the percussion gun 105 grains. I am currently working on a reduced load for plinking. Hoping for something around 35-40 grains.

My Renegade 58 reborn is so consistent all up and down the load scale that I haven't given much thought to load development. But, it's not for match shooting so that's a factor.

My tc 54 rebore is the same. 50 grains for match and 90 for the hunt.

Thanks everyone. Definitely for hunting, so I'll start at 90 and go up.

Grimord: I'm working on getting the 56 SB working with a .530 rb and jeans for a patch. I think that I need to start at 60 gr. FFg and work up from there.

I have a Renegade 50, Hoyt bored to .580" with 1:40 twist,
and shoots a special cast 600 grain Maxi-Ball. Shoots best with 70 grains weighed 3F.

My ,58 caliber is a .54 New Englander re-bored and rifled by Mr. Hoyt. The barrel has rounded grooves with a 1/66" twist rate. The sights are from a Remington 700 rifle.

Using 100 grains of Black MZ powder and a .570 ball;, five shot groups at 78 yards measure 1.1-1.3"

Hello everyone, I just got the barrel back from Mr. Hoyt, it looks good, but the crown is a bit sharp. Can anyone send me to a post on how to smooth it out, please!

I'm excited, but I also need to find the engraving attachments for my Dremel to change 50 into 58.
