recardoa Posted October 29, 2009 Share Posted October 29, 2009 I am working up a load for service stock revolver using VV N320. I chrono'd a 158g RNFP so far at 4.6g screaming by the sensors at 747.3 Average FPS. That is only a Power Factor of 118.07. Manual says only go up to 4.8g. Any reccommendations on going up that high with Smith 4 inch 686 revo? I gotz no problems with going there, but was interested in what the field had to say. Already bought 1,000 158g. recardoa Link to comment Share on other sites More sharing options...
Toolguy Posted October 30, 2009 Share Posted October 30, 2009 You're loading 38 spl loads in a good quality 357 gun. It could do 4.8 of V V 320 for a lifetime. Link to comment Share on other sites More sharing options...

Oh yea, you are headed in the right direction. Link to comment Share on other sites More sharing options...
recardoa Posted October 30, 2009 Author Share Posted October 30, 2009 Toolguy & Pigfixer: Thanks for the thumbs up and speedy response! I will keep those interested in the progress in the loop!! recardoa Link to comment Share on other sites More sharing options...
Bones Posted October 30, 2009 Share Posted October 30, 2009 (edited) I use 4.8b gr VV N320 and 158 gr plated RN bullets (0.693" long) seated to 1.500" coal for SSR and get 840 fps +/-10 out of all my 4" revolvers. That load makes IDPA SSR PF in most of my 3" revolvers as well. If you practice enough with that load to wear out your 686, you will be a force to be reckoned with.

I got up to 4.5 grains, then decided to go shorter. Was loading Berry's 158 flat point. It's amazing the variance you will see, depending if the powder is towards the primer or towards the bullet. I was getting almost 80 fps difference. Seiichi Link to comment Share on other sites More sharing options...
GunslingerDK Posted November 6, 2009 Share Posted November 6, 2009 I would say it's perfectly safe in a Smith & Wesson. I have tested some .38 Special +P not long ago. These were made with 120gr cast boolits and 6.4gr N320... Link to comment Share on other sites More sharing options...
