I tried the 370 maxiballs with 70gr BH209, these hold 1 1/2: groups in my wolf but at 50 yards in the LDR, they shot poorly. I will experiment with powder charges tomorrow if i take it out shooting. I loved the 250 sabertooth bullets though! They loaded extremely easy and so I could not recommend them for hunting in this rifle. I am going to clean the gun and see if i can get the bullet to fall out of the bore like what they did to me one year while hunting LOL.
