I just bought a .45 cal barrel for my T/C Encore. From what I understand T/C made them with a 1:28 twist rate, same as the .50 cals. I can't wait to get it and try it out as soon as this weather breaks. I have a blued 209x50 barrel that is in great shape that I might be putting on the classifieds. Anyone interested keep your eyes open or send me a PM.
Once it starts to cool down I now have 3 muzzys to sight in

Bronko,I have a 45 Encore, it shoots a gong a bit over 6 inches in diameter at 250 yds. with real consistence when I don't mess up [it is the longest range I have available] the load I use is 120 gr BH a Harvester 50/40 smooth sabot and a 40 caliber 200 gr shock wave.

Im thinking of using a similar load. I have a bunch of 200 gr XTPs and Harvester blue CR sabots.

The 200 gr. XTP was the only 200 gr. I tried that would not shoot accurately in mine.

Really?! They shot excellent out of my 1:30 GM barrel. Have you used the shockwaves on deer? If so how did they perform?

The 200 grain XTPs shoot great out of my 1:30 GM barrel also.

With that bullet in Harvester's H4540BR (crush rib) sabot and a mere 65 grains of GOEX FFFg I get a bit over 1500 fps fifteen feet from the muzzle with 1.5" 100 yard groups. That load was deadly on the three deer I've shot with it - all pass throughs with all the signs of perfect expansion.

I did find accuracy with that bullet falls off if I tried to push them to higher velocities.

My other computer crashed and I lost my target pictures but as I recall I used 70 gr of Pyrodex P and had similar results. I have several .45 caliber conicals I want to try in this barrel also.

I have shot several deer with them ,one at 20 yds. one at 35 and one at 86. they all were hit ib both lungs over the top of the heart ,the two close ones dropped in 20 yds. or less the 86 run about 50 yds,

Clem, a fellow DWB by the name of Bob Bowers converted a White 451 bbl with the 1-20 twist to fit on my son's TC Encore. Unfortunately, with his busy schedule, he's yet to try it out. I may have to try it out myself. GRIN
