I got the latest flyer from Rock Island Aresenal and they have a M70 target gun in the original wooden crate in 35 Rem. I'm guessing it's the same one as in Rule's book. My question is who would have ever ordered a target gun in 35Rem?
This is very curious. My thoughts are a full National Match course is 200,300 and 600 yards and you are not going to shoot that with a 35 rem. Most local clubs didn't and don't have much more than 100 yard ranges and there are targets and matches known as reduced course matches with simulated targets at 100 yards.
This guy probably was shooting reduced matches but why a 35 Remington. Two thoughts are his hunting rifle was a 35 Remington and he was comfortable with it and had components and possibly cast bullets ready to load. Or, and if a 30 cal bullet just misses breaking a scoring ring a 35 cal would break that line and that might of been his thinking as well.
I would love to know because it certainly isn't or has been a normal choice for a match rifle cartridge.
