Guest cookoff013 Posted August 1, 2017 Report Share Posted August 1, 2017 dave, nice to meet you. welcome to the pigeonwatch.... i`ve been playing with some 12bore homeloads and i completed an experiment. it was to get a load running and switch it out to many nontoxics. i switched out the volume, so i tecnically can use the MEC LEAD bar to meanure the right amount of shot. i tried alot of nontoxics, steel,copper,itx,bismuth,niceshot and lead. the lead came out at the highest pressure... all other nontoxics the pressure was lower. i`m not saying you can do this without consequence.... but it gives you a start on what to achieve, and what loads can be made what shotweight of lead do you use? / reload already?

Dave53 Posted August 1, 2017 Author Report Share Posted August 1, 2017 Thanks for the reply cookoff013 loaded 12 bore in the past but not worth it now. Loading 28 bore at the moment lead 24grams on a mec 600, but want to load 20b bismuth ready for the season,can I duplicate the lead load for bismuth as they are similar sg.Dave Quote Link to comment Share on other sites More sharing options...
