I recently brought 1 of these back from Wisconsin (I'm originally from the Beloit area) to Vegas so my son can hunt the black powder muley season here. I am having problems geting this zeroed with the Irons (no scopes allowed here during BP season).

I am using the 240 gr hornady xtp sabot over 3 50 gr pyrodex pellets and musket caps. I cant get this thing to come down enough, I've run out of adjustment in the rear sight and I'm still 5 inches high at 25 yds. According to the load data available, this load should put me zero at 100 and +.7" at 50 yds. Don't really care for the fiber optic irons that it came with, but I'm kinda stuck with them. Is it possible that they shipped this with the wrong front blade height, I suppose stranger things have happened.

Any ideas?

I have the same rifle. The first thing I would suggest is contacting T/C to see what they suggest. Personally I shoot loose powder out of mine.



Mine has the fiber optic sights. I used a six o'clock hole on the sights until the laws changed and now there is a 4x32mm Simmons Pro Diamond scope on it.




This is my load of course. And it is a good shooter with 110 grains of powder.

Try to bury that front sight further down into the sight for now. Also I would try loose powder. Start at 100 grains or use two pellets. Three pellets is a lot of power.

I agree that loose powder is the way to go. I know that today's MZ's are rated for 150 grains of powder, or three pellets, but I have found that at those loads, acuracy is diminished. Most of my T/C sidelocks perform best in the 90, to 100 grains of powder range. (greatest accuracy). a few years back I bought a new T/C Encore Katahdin, in .50. It consistently shot high, even with the rear sight adjusted all the way down. I called T/C, and they sent me a taller front sight, I installed it and now it shoots fine.

That extra pellet adds to the recoil with out add to much to the velocity if its not burning fast enough. Try two pellets as that's what usually is most accurate other than that loose is always better cheaper and more efficient and 110 gr would normally be accurate. Part of the problem is that's a side lock designed to use a #11 cap or a musket cap Pellets work best with a 209 ignition. Irregardless of the advertising that gun will always function better with loose powder because that's what the ignition is suited to, you may have ignition problems in cold weather and with #11 caps I doubt you are even close to burning 3 pellets with any efficiency, with Musket caps and a Musket nipple it would do some better but still short of what a 209 would do.
