Bloke does not say your local in W.A but if your near Perth try Beaton firearms they just did up a repo No.4 T to the correct specs and this thing groups 1" at 100 yds.............. yes I know Mr Laidlericon that is well above what the real deals are supposed to do but sometimes it all gels and you end up with a freaky one even for a repro.
Or try Roy Alexander & Sons in Perth also good on 303's as well I tried those no smith things bloody useless but if you go to a gunny get them to check out the bedding as well but they should have a good knowledge of the 303 and bedding them.
These are old rifles with a checkered past and were not really pampered like the plastic fantastics we have now days.
