Just curious when all of you changed you bored from one size to a larger size what did you do about ramrod size and the pipe size?
Using the same ramrods. As they will only be used for reloads while in the field and I use a starter, I see no need to change them. I used brass range rods for cleaning, range use and initial loading before hunting.
My buddy has one we got from @kelljp . Shoots great groups with 375gr CVA deerslayer bullets. He is very happy with it.
I am heading out today to work on velocity loads with a magnetospeed chronometer using triple 7 3F in three T/C Renegade barrels bored out by Hoyt.
58 cal 24" 500 gr MV 1350-1400fps
54 cal 24" 485 gr MV 1450-1500fps
54 cal 21" 425gr MV 1400-1450fps
Target velocities above. Starting loads will be 100 gr of T7 3F and adjust +/- to try to reach target velocities. Accuracy loads will follow once I establish what velocities I can expect.
RIO musket caps
Internal ballistics were developed with an eye on what I want to achieve with external ballistics and the energy I would like down range (terminal ballistics)
Velocities were derived from the charts below on T7 load data from the source and from comparing it to the results from the p-max calculator provided by Dale Allen Raby.
https://www.p-max.uk/cgi-bin/black_powder.cgi
All loads have a 99% burn in the barrels (if it was BP)
I will start a new thread and provide a link to it in this thread.

Can you explain why the use of musket caps? Was it availability or just a hotter primer?
Hotter more reliable primer ignition on the T7
Bobby does nice work. But wow, I don't envy you shooting that big slug out of that rifle. That's going to be punishing on both ends!
No worse than a 12 ga duck or pheasant load. Go back and read post #34.
Everyone assumes that the recoil is abusive, everyone is patently wrong.
