I used Seafire 223 blue dot loads and they work very well. Trail Boss is more accurate out of my rifle and I have 12 cans of Trail Boss so I'll use that till I run out of it. But its good to have something to fall back on when I do run out. Blue Dot shoots around 3/4" @ 100 yards where Trail Boss will hold around 3/8" group. With 8.0grs of Trail Boss and sighted in @ 50 yards it prints 2" low @ 100 with a Sierra 55gr HPBT GameKing bullet out of a Savage Axis with a chopped off 18" barrel. Don't know the fps, as this is my squirrel rifle and dont really care.

Going to try Trail Boss and Blue Dot in a 243 this week, have a very good supply of Sierra 85gr HPBT
