Hello, I have an chance to purchase a almost new, barrel looks good, Lyman Great plains hunter in 54 cal. What can I expect for accuracy with this rifleare there barrels well made. I would probably be shooting sabots in the 250gr range.I have a Green mountain Long-Range-Hunter Barrel on my 50 cal TC hawken and it shoots great. I shoot the 250gr shockwaves in my TC and I would like to use the same style of bullet in the lyman 54. I use 100 gr of triple 7 in the 50 and was wondering if that would be about the same in the 54. I ama bitconcerned about purchasing the Lyman54, and then finding out that its not the shooter that my TC is.( also due to the fact the barrel is stamped Made in Italy )thanks for the help. Steve
