That happens but is fairly rare. More common on late war Brit no.4 rifles in my experience than on other models and eras.I have seen a few that headspace fine but the chambers are way oversize and just destroy brass.
and that is something you cant fix with a new bolthead
Very kind of you. I'm between Sudbury and North Bay.Where abouts are you? I think I may have a set of gauges kicking around you can check your rifle with
I have a Martini that has a large chamber that I dedicate 50 brass to. After I neck size not a problem. I full length resize my cast loads and use them in all my rifles. If I fire other brass in it they don’t last. It will chamber my fired brass from any 303 I’ve tried. Sometimes you just have to work with what you have.I have seen a few that headspace fine but the chambers are way oversize and just destroy brass.
