Hi All,
I am new to this forum but I have some experience using Trailboss. I loaded up some 38 Sp for use in my Taurus 357 M66. I like the powder for its bulkiness. I had an issue with my Taurus just after getting it. I had shot 6 rounds then the gun blewup. The cylinder peeled itself open and the top strap blew off. Luckily Taurus has a no questions asked life time warrantee. They replaced it. The up shot is, I was very skittish shooting this gun for a long time. The Trailboss eliminates the possibility of a double charge and it generally produces a ligher load. As far as accuracy is concerned, those 38 spc at max load and a Cast SWC HP GC I had the some of the best groups at 25 yrds.
Good Luck
Sincerely,
Reverend Richard
