Thanks, I will buy a pmag and try to alter one of my factory clips. I sure don't won't to mess with this load. After one round to find where I was on the paper at 100 yds., I put four rounds in two joining holes less than a dime. I had 35 more test rounds I didn't even want to shoot after that. But I did, couldn't help myself. No other combo was as good. I did get a 1/2" out of one other load. Let you know later how the new mags work and how the mag alteration goes.
