I've seen the results of those Lehigh bullets both from the old man and Alex both. The only smoker I own that will shoot a sabot is my Renegade and only XTP's will shoot worth a flip out of it. I tried some of Alex's 220gr .458 CF's out of it. Not good results at all. The best group I got out of it was well over 3.5 inches with a 90 grain Swiss FFG load. Maybe those 230gr new ones you recommended will do better. I have dad's Thompson Center and that smokeless demon spawn as well but I'm just not that into inlines. They just don't twist my crank. I do have to admit that smokeless is fun to shoot and I will most definitely take it on an Elk hunt but my main focus is my smoke poles.
