Recently I ran a brief test to compare different primers with 2400 powder and cast bullets in my S&W md 28 with 4" barrel. The load was
14.8 grs of old Hercules 2400, Win. brass and a hard cast 158 gr SWC
of the bevel base type with hard blue lube often seen at gun shows and
sold by various vendors. Five rounds of each with five different primers
ran; Win SP avg. 1222 fps, CCI 500 SP avg. 1237 fps, Rem. 1 1/2 SP
avg. 1244 fps, Rem. 7 1/2 SR avg. 1245 fps, CCI 400 SR avg. 1247 fps.
Win. 296 powder in Win. brass and Win. SPM primers and jacketed
bullets were tried; 16.6 grs and 158 gr Hornady XTP avg. 1114 fps,
17.2 grs and 150 gr Sierra HP avg. 1131 fps, 18.8 grs and 140 gr Speer
HP avg. 1173 fps and 21 grs and 125 gr Sierra HP avg. 1335 fps. I was
a bit disappointed with the velocities of the jacketed bullets and see
little reason to use them in the 158 gr weight.
