Zeke - I had a M1917, Winchester made, and love it. Liek the Gunnut69, I left my barrel at 26". She would shoot like no other 06 I have ever enjoyed - she preferred the fastest and heaviest loads I could put down that tube and usually put them inot less than one inch at 100m.
I sporterized mine with a Timney Trigger, a cock on opening kit, scoped it, had the floorplate straightened and Gunnut is right, she looks a lot slimmer and sweeter with the floorplate straightened.
I think that if I encounter another of those M1917s and it is in good shape, barrel and action, she will get sporterized for easy carry and field use - but I would leave the barrel at either 22 or 24". Just my thoughts. Mikey.
