I haven't noticed anyone mentioning using conicals cast from Lee R.E.A.L. moulds. I've been doing this for several years with good results in a homebuilt flintlock with an Orion fast twist barrel. Casting a 250 gr slug, lubing with SPG lube and loading over 85 gr of 777 gives just under 1400 fps. Most recently, I tried them in a T/C Impact with 80 gr of Blackhorn209. Velocity increased to just over 1600 fps with promising accuracy...and much more noticeable recoil. I haven't always gotten complete pass-throughs on deer at the lower velocity, especially if bones were hit. The higher velocity from the Impact should solve that problem. Anybody else have any success with these?
