I picked up this Winchester M1917 recently and I was curious if the numbers on the stock and bolt were orginal or an after thought by a previous owner. It also has a stamp near the magazine cover that I can't make out. Seems to have the orginal 5groove barrel dated 7-18 and the stock is stamped on the end, near the front band with an "R". Barrel cleaned up nicely and I can't wait to take her to the range. I plan to use 312-185, sized .311, starting with 27grs of H4895 w/poly fill. I hope she's a shooter. Any info is apprciated.
