Thread: Fireforming case with cleaning patches and pistol powder

I have a g1 and fire formed new 3030 to 7-30. Tried patches but didn't work great although I should have experimented more and most likely it would have. Instead I annealed the new brass then through the sizer but was half way through before I remembered to check the donut for head spacing while forming since it's an improved case so shoulder is going forward and you need it touching both ends of the case. So I just loaded into the lands a bit. I got some of shootenz cast bullets as I figured they are cheap and a light load of trailboss but not subsonic, around 1300fps did the job well and didn't have to worry about pressure being in the lands. I thought more gentle on the case since 3030 is so thin than a full power load to form. Have had no split necks and formed pretty well, the shoulders did slightly sharpen on the first full load but speed and accuracy were fine. It also gives you loads for practice, sub and shooting rabbits etc.
