This could be useful to some of you. For all of 2009 I could not get small pistol primers. My son in North Carolina found 2500 just before Christmas. Nice gift. Last spring I had 1400 small rifle primers on hand, so I worked up a load for my 610. I shoot .40 S&W most of the time so that is what I worked up with the rifle primers. I assumed I needed to back down my powder charge because of the primers, so I did and worked up. I wanted 900fps using TITEGROUP.
Mixed brass, TITEGROUP powder 3.9gr hand measured one at a time, 180g lead TC hardcast actual weight about 185gr, OAL 1.135. Velocity measured with a Green Shooting CHRONY at 10ft.
Federal small rifle primers #205. 896, 882, error, 870, 913, 915. average 895
Federal small pistol primers #100. 911, 890, 896, 897, 874, 895. average 894
The only difference I can find is the #100 primers are slightly flatter after firing. Primers appear to be identical. The 205’s may be slightly harder. I did not test for accuracy.
Anyone wishing to use this info, do so at your own risk. This load may not work the same in your gun.
