Hi All, thank you for the posts. I might figure this out some day. Perhaps a better question is.... Has anyone duplicated the LT projectile?

I can order the Fosbery 730gr mould... and with a little load tinkering arrive at the 1,100 fps. It would be nice to know that others, without load details, have achieved this as well.
Thx.

I have a few pics, but lack the skill set to post them.
