[QUOTE="Jimm, post: 76024, member: 9"] Hey cowman [img]/ubbthreads/images/graemlins/smile.gif[/img], I am working the same project as you are working towards.To fireform my cases initially I picked a upper end load of powder that I knew had performed well in my std. .243.( 38 grs. of IMR 4350) I used a 107 smk seated touching the lands.My twist is 7.5. 100 YD. groups( 14 rounds) were about 1.75 " But ! 300 yd groups were about 1.5"( guess the settled down by then) My thought on this is that you could play with diff bullet wt. on you fire form loads ,but you will still need to develope your loads after you have fireformed your cases. Are you neck sizing only ? Jim [/QUOTE]
