Was reading a Backwoodsman mag. article about roundball loads in a mosin w/ a .32 chamber insert, and got ta' thinkin- picked up some .310 dia balls,put 'em in a 30-30 case over .3cc's of red dot. Wow! 3 shots touching at 25 yds, about 3/4 inch penetration in a 2x4. With .5cc's of powder, blows a big hole out the back of the 2x4. Gonna be fun!
