10ML Original black and .452 FTX

[cfvickers]

I acquired a box of .452 FTX 250 grain. What sabot would be best and of RL10x, both 4198s imr4895, and H322 do any of you guys suggest a load for out to 200 yards? I have 28 lbs of powder in my reloading room 26 are different, I really don't want to buy something special for the ML. My dad is an ammo dealer at gun shows and someone sent him the box of FTX to for me to try but I have no .452 bore diameter guns,I know they will work with the MLs. and should be good deer bullets.

CF,
My Thumbhole 50 shoots best with the MMP-Short Black sabot, and slightly knurling the bullet, but it has a bit larger bore than some. I have shot several loads with 250 gr FTX. From about 58 to 65 gr H-4198., 62-65 gr RE-7, 60-70 gr of 10X. I have also tried several duplexes. 10/55 N-110/H-4198, 10/58 N-110/RE-7, 10/60 N-110/10X. I plan to try some N-120 singles and duplexes next range session.
