went on an early morning drive to purchase s.r. &L.r. primers the drive was nice but boy was I upset with myself when I got home and put on my glasses to inspect my "catch or should i say screwup of the day)...(birthday no less)anyway, the small primers are ok,but the large are "for magnum loads" and yes here comes the all important question. If using H4895 (35.5 gr ) in a 22-250 with a 52 grain hpbt match bullet can i substitute magnum for standard primers without pressure problems? sorry for being so "winded", would appreciate your fella's thoughts.
