Thread: BSA Hunter help required.

I have recently acquired a BSA hunter. Whilst it is a very nice rifle and a nice rifle to handle, it has three problems I would like some advice with:

1)The trigger is terrible like a cheap 22 trigger
I have googled the exploded diagrams and adjustment instructions but this one has a problem with the pull weight adjustment screw on the top of the trigger. Instead of a socket headed screw there is a very short ( only hole width long ) slot head grub screw. Removing one of the other screws and trying it as a replacement makes no difference to the 'pull'.

2) The firing pin mainspring was quite rusty with some pitting on the spring and striker rod. I have polished the rod with 1200 paper and cleaned up the spring. The spring looks a bit tired and I wonder if anyone would have one or could make a suggestion.

3) The half open bolt position is weak compared to the firm positive hold BSA rifles normally have. Is this solely due to the mainspring condition or could it be due to wear on the striker rod cocking piece ?

Im no help other than to say there is a number of spring makers in NZ.

Springs are a little different in the bsa triggers. If the "adjustment" isn't working I would look at a spring change. My Hunter had an abomination of a trigger job done on it. Sear spring was knackered and the cocking piece on bolt and sear had 45 degree angles put on it making it slam fire when the bolt was closed. A bit of a rat through a box of springs at a gunshop and angle changes bought it back nice and crisp.

Half cock can be the notch in the bolt body for cocking piece. Does it still fire ok, are you getting soft strikes?

Previous owner didnt use it very much but shot it without misfire. The cocking piece has a slight flat worn on it, I can tidy the notch in the bolt body with a chainsaw file but really need a bolt from a perfectly functioning rifle as a reference for measurement comparison

Have to have a look at it when I pick up my stuff
Good aquisition

Did you buy a new car - freudian slip?

I'll get a picture of my one for you.

Hugh Bradley years ago had a lot of surplus BSA parts. Might be worth contacting him in Alex maybe? He did the trigger work on my Hunter 257 Ackley, nice job (again years ago)

Gee that would have been a perfect rifle !

I have quite a few BSA parts here.

@Mathias any photos of said rifle?

As for the OP... try contacting Allen Carr

There you go

Yes, to a point. The straight case caused the holdup when going into the chamber if you didn't stroke the bolt fast. This is due to the controlled feeding and overall length of loaded round not being long enough to line up without binding, when tipping into chamber.
