[QUOTE="Ridge Runner, post: 287613, member: 951"] min. body taper and sharp shoulders make trimming cases almost unheard of. you shoot higher pressure with less pressure signs so you get higher velocity. You can fireform without bullets, just charge with 19-20 gr of unique, fill the case with corn meal, tap the case to settle the meal, then plug it with a rolled up "worm" of paper towel, press it in tight with a punch or small allen wrench. I form cases like this all the time, but I do vary the charge depending on case capacity. However, do not discount the accuracy potential of fireform loads, when I used moderate loads to fireform 338 LM cases to 7mm Allen mag, my fireform loads would shoot in the .2's here is a target [IMG]http://i66.photobucket.com/albums/h274/wv_Ridge_Runner/fireformgroup7mmAM.jpg[/IMG] RR [/QUOTE]
