I too am checking zero on my White Mountain TC carbine. I put Sally Hansen fluorescent nail polish on the front sight bead and sometimes blade and set it in the half round rear sight notch. The rear sight is adjustable for both windage and elevation. The Thompson Center coil spring lock does have a fly but the simple single trigger is like 8 pound pull and very coarse. Either stoning the sear for smoother trigger or replacing with a double set double phase (two triggers) or double phase single set (single) trigger would be an improvement. Track of the Wolf advertised a replacement double set double trigger but could not find the name of the maker. It would require inletting for it and replacing the trigger guard. Mine is a fairly recent acquisition but three shots at three different big game animals with one shot harvest each is pretty good for this entry level muzzle loader compared to custom made rifles I normally hunt with. Shots made at 15, 35 and 60 yds. As to targets I get cheap Dollar Store or Dollar General 8" lime green paper party plates, staple a 3" aluminum mini pie tie and for 25 yds center a blaze orange dot on the tin. This target shows up well out to 100 yards. I cover the intended point of impact with my front sight bead. Using the same target from 25 to 100 yds gives me a reference for hold over or below. Fortunately one of the ml gun ranges I use have benches at 25, 50 and 100 yds and a target board at 75 yds. I practice offhand, sitting and off cross sticks once the rifle is zeroed for 50 yds off the bench. Before season I shoot wearing the same clothes and backpack and blaze orange vest and cap I would be hunting in and reload from whatever system I will be carrying during the hunt.
