Data from range
I made it to the range today to test out the N340 loads. Excellent shooters, with a fairly stout recoil. Very accurate in my 629 Classic 5.5", ported. Clean and very consistent velocities.
Attached is the compiled report data from 5 strings of 10 shots. The loads were 10.3; 10.5; 10.7; 11.0; 11.2
With standard deviations in the 13 fps range, I am very excited for the potential for this powder.
Average Velocity of 1108; 1121; 1133; 1148; 1167, which is nice and linear.
Powder charges fill the case nicely around the 11 gr. mark. Brass was just starting to stick at the max charge tested, but not to the point that it would prevent use of that charge.
All in all, it looks to me that N340 is a happy camper in the .44 Mag. Your mileage may vary.
