The other day I had a chance to test Saeco #315 in one of my K-31's using the bump die Smokemjoe made for me. #315 has been a stellar performer in both of my K-31's, but I couldn't seat it longer than 2.82" or maybe 2.83" and sometimes had to rap either rifle's bolt smartly with the heel of my hand to get it to go into battery. Joe's bump die reduces the nose and first driving band enough to allow me to seat them to 3.03" and without smacking the bolt either. The target below shows 1 sighter at the very top and then two groups: A very tight group above the bullseye and four within it (my last 4 shots). I changed my point of aim slightly for those last four. The load was 20.6grs. WC 820 with CCI primers and once-fired Graf's brass. Btw, the rifle is as issued except for "accurizing" it as per Pierre Ste. Marie's description on the Swiss Rifles forum (very easy to do if you have the washers and loctite on hand). Just for grins, I'd like to try Ly. #311291 and Lee C309-180-R in the bump die also, since they shoot almost as well as #315, but have to be seated rather deeply (to the crimp groove) if you want to avoid rapping the bolt. Btw -794 (top of target) is the last three digits of the serial no. of the K-31 I used. I have to keep them separate because the sight settings (elevation) are different.
