Hello 93x64mm,

Thanks for the reply.

The 270g bullets did worse. The 300g bullets were 4" - 5" wide at an average velocity of about 1825 fps. The 270g bullets had a wider spread with a 1840 fps average. They also had vertical dispersion . (R = low right, L = high left). Next I'll be trying some more 300g bullets at a higher and slower velocity, with different powders.
