I had one of the newer ones in 45-70 and really liked it. They are pretty heavy but that is ok as it helps absorb the recoil. I played around with a number of loads including black powder. The factory told me it was regulated for Remington 400 grain at 50 yards. I even tried some paper patch bullets. It would shoot 2 inch groups at 75 yards with most 400 grain or heavier bullets.
Due to the times I sold it but have kicked myself numerous times for that. All in all it is a very well made rifle, wood to metal was excellent as the blue finish, just a tad heavy for me. I might have kept it if I didn't already have 6 rifles in the same caliber and hadn't needed the money.
