This is a load for my 38 Super SA MIL-SPEC.
I loaded some Speer 124g TMJ bullets in Starline Super Comp Brass with from 6.8g to 7.2g of Power Pistol in .1g increments. All had CCI #500 Small Pistol primers.
6.8g = 1242
6.9g = 1255
7.0g = 1275
7.1g = 1291
7.2g = 1290
7.2g = 1281 w/Fed 100 Sm Pis Primer
Can anyone explain the drop in velocity from 7.1g to 7.2g? Not a hot enough primer? Is this why I hear about the IPSC folks using small rifle primers? The CCI primer showed no signs of flattening out. Of course the Federals did. Any advice/wisdom would be welcome.
