Loaded some .300 Wthby rounds with 24gr of trailboss behind a 155gr jacketed bullet.I have yet to try it but i'm hoping for a nice mild recoil for my kid to try.What kind of velocities should I expect?
For some of us, well me any ways. I went to Trailboss to avoid the whole filler/no filler deal. Used 5744 for big bores and didn't like having that big airspace but research revealed the possibility of "ringing" a chamber with fillers. Trailboss and problem solved and controversy avoided.
