Thread: 308 Subsonic powder alternative to Trailboss

Cheers for the info guys..
I had a little play around myself last week as I have some a few pistol powders and large pistol primers (as large rifle primers are the price of gold). Using AP350, Started at 9gr and worked my way down to 6.4gr until I got to 1070fps.(some precautions were taken) Tried 10 more and found Burn was clean and primers all looked ok and nothing out of the ordinary to report and speed range between 1049 -1072fps. Will try for accuracy soon.
There are probably a few alarm bells sounding off at the moment and if so moderators please delete this post if you feel im stepping out of bounds.
