N340 load data using 125 tc lead for 9mm

[Pizzaman]

I have been following the forum for some time. Very informative to say the least.  I recently bought some vv340 and was hoping to use it for 9mm   125 tc lead bullets . Tried 4.9g  that gave 1142fps from Xde. Not very accurate though  Looking to develop a load that I practice with using lead (indoor range required) that will impact near point of aim  Any input will be greatly appreciated

What was wrong with your accuracy - or what was wrong with your point of impact? (not the same thing necessarily)

 

Your velocity is pretty much in the ballpark for what I would expect following Vihtavuori data for the Rainier 124gr RN lead bullet: https://www.vihtavuori.com/reloading-data/handgun-reloading/?cartridge=89

 

Many feel that N340 is a bit on the slow burning side for 9mm Minor loads.

I have found that playing with crimp and using magnum primer is the solution here. Probly all the powder is not even burning.

Shooting off bench at 15 yd line produced ~2”  5 shot group, at 11 o’clock 5 “ from poa.  Have used bullseye ,hp-38 and tg all giving me   Respectable accuracy.  I wanted to try a different powder , was hoping to find n320 or SP, had to settle for n340

Try 0.2gr more powder. That might get the bullet out of the barrel quicker, so they impact lower.

Will give the extra charge a try. Thank you for the feedback
