My group fliers with a .30-30 lever are yawing ever so slightly. Typically I'll see 3 or 4 shots in a cloverleaf and a flier 1" out. Range: 25 yds. Bullet weight is 180-185 grains. I'm shooting light loads of fast burning pistol and shotgun powders (6.5-8.0 grs) and also light loads of AA5744 (12-14 grains).
Will increasing the powder charge take care of the yawed fliers?
If not, what are the other possible causes?
Thanks.
