Re: TC Thunder Hawk
the screw is under the sight ,nock out the sight with a brass punch or wood dowel.
I have my thunderhawk for years gun has never failed in rain sleet or snow,I like RWS 1075+ caps used with a t/c flamethrower nipple and 85 grains of triple 777 and a buffalo 375 SSB bullet/sabot
I found nothing walks from this load and is good to about 130 yds
