I was loading for my buddy's 300 Win Mag and tinkered with some Trail Boss. Capacity was 20 grains. Per Trail Boss' instructions one could go as low as 70% of capacity. Well, let me tell you that 14 grains isn't enough to push that Barnes TTSX out of his 26" barrel. Talk about an Oh Sh*t moment. Luckily it was only about 1" from the muzzle. I put some Break Free down the pipe and let it sit a while while I cleaned my rifle and then pushed his bullet out from the breech end with my Tipton rod. FWIW 20 grain gave us 1300 fps.
