Recently I won a raffle and got a nice M1867 Spencer Repeating Rifle. Cant find any brass or ammo so I cant shoot it but I did get a centerfire block for it.... lol. I was doing work for helping out a farmer and after fixing one of his tractors he gave me some money and a fixer upper trapdoor Springfield carbine that was cut down from a rifle and has a 27 inch barrel rather than a 22 inch barrel professionally done by a company back in the day for Sears & Roebuck and not some hacksaw crazy guy. However the guy through another job my way and asked that if I took less cash I could take a pick of some more rifles. This guy is 83 and his kids said they are gonna sell his hard earned collection anyways so he figures lightening his rifle collection while giving his kids good condition farm equipment is a better plan. He has two Winchester Semi Automatic Rifles that perked my interest. He has a Model 1907 in .351 Winchester and a Model 1910 in .401 Winchester. Both are appear to be straight walled and something I could use for deer hunting in my state and was wondering if they were good deer hunting rounds. He has 55 rounds and 75pcs of brass of .351 Win and two 5rnd magazines for the 1907 and he has 30 rounds of .401 and 46pcs of brass for the 1910 only having 1 magazine though. Neither rifle has reloading dies provided as he cant find them anywhere. The 1907 is the least amount of cash taken off of the repair bill and the 1910 is the highest. Is the .351 adequate enough for White Tail deer out to say 80~100 yards ? I see ammunition is more plentiful for the .351 than the .401. Should I ask him for the .351 or the .401 ? Also if these rifles are terrible I guess I wont take either I thought they looked cool and figured they might be useful for deer hunting. If they aren't I guess let me know lol. Also both rifles are in a good condition for their age with the 1910 looking the best but neither are that collector grade where if you passed it up you would never see it again type deal. Thanks for all replies.
