My dad has an old BSA Sportsman’s 15 from his younger days and I took it out to the range the other week after giving it a good clean etc.
Issue is, the bolt requires quite a lot of force to close. Having done a bit of poking around, I’ve realised that the tension/stiffness is caused when the bolt engages the switch to lower the plate which allows a round to load in from the tube magazine. This only happens in the bolt’s last cm or so of travel.
My question is, is it normal for a bolt action which feeds from a tube magazine to be stiff like this?
I apologise for not knowing the correct terminology for all the parts.
