Jason - yes, it's a very light load, not my usual load, I usually shoot 20 grains. The T/C Patriot has an unfortunate tendency to crack it's stock; various shooters have theorized it is the result overtightening the lock bolt, overcharging it by using more than 20-25 grains, or a design flaw in the stock or a combination thereof to name a few I've heard.
I'm hoping to keep it shooting for a while longer so I stick with 20 grains. I did shoot that load unusually well it at the last FOML club shoot, with three 10X and 1 10 at 50 yards.
