Just back from a chrono check of some .45acp loads using V-V N340. I was loading Rem 185gr jhp bullets in new Starline cases with Win large pistol primers. OAL was 1.215." Velocities were low. 7.5gr of V-V N340 was only getting an average of 885fps from my S.A. "compact" (4"bbl). This is too low to qualify at an IDPA meet (need 892 fps for a 185 gr bullet). I'm nervous about jacking up the charges to the levels shown on the V-V site. Both Speer and Sierra show charge weights much less than V-V does. Also, V-V states that they were using a "6" test barrel" whereas Speer and Sierra were using real guns. Anybody out there actually dumping 7.7gr (or more?!?) of V-V N340 into a case with a 185 on top? How's the velocities? And, more importantly, how's your gun? (p.s. 9.7 gr of AA#5 with same load specs was giving an average of 928 fps.) Stay safe.
