TRG65 Posted December 8, 2002 Share Posted December 8, 2002 I noticed that West Coast Gold bullets make their 9mm 147 gr RN in both .3555 and .357 diameters so I purchased 200 of each. I'm shooting a Bar-sto barrel in a Glock 34 and have a load for a 147 .3555 of 3.3 gr of VV-320 with a FSPM primer and an OAL of 1.155, which gives about 126-127pf. My hope is that the larger diameter would give more bearing surface, tighter seal, more constistant ignition and better accuracy. But I haven't been able to find any data on what a safe starting load would be for the .357. I emailed Irv Stone and he said either diameter would work in the 9mm barrel with the right load. Any suggestions how much I should reduce the powder by as a starting point? Link to comment Share on other sites More sharing options...
Patrick Sweeney Posted December 9, 2002 Share Posted December 9, 2002 At 3.3 I don't see you getting into trouble with the load you have. Try it, and do a side by side comparison of velocity, SD, ES, accuracy and ejection distance/pattern. You probably won't find much difference at all.
