i recently picked up a 350 rem mag with 120+ rounds of reloads the owner made. he also wrote down grain info. and put that info. into each box of loads he made. (and date) all of which date around 70/71
there is also a weaver scope on it. i have the receipt for the scope as well. $47 bought on 8/18/69.
i can only assume the rifle was purchased in 69 as well. why make loads for a gun you dont yet own? right?
so,, i go to Remington.com and look up center-fire rifles by caliber.
there is only one in that caliber, claims it is still in production. (no asterisk next to it) and that it was introduced in 1983. wrong gun i assume... so what gives?
here is the page before.
