My question on VV-N350 was answered, finally, in this months issue of Handloader. According to the reply their load of 10.0 gr of VV-N350 under a 180 GD @1.250-1.260 Starline was pressure tested to be within industry pressure limits. Speer #14 shows a max load of 9.7 grains. I was getting all smiles with 9.5 gr in a Glock G20SF. Which proves?.........work UP to max loads.

This was the original thread for anyone interested:
