Bobby:
I'm shooting 180 XTP bullets in my 14" Maximum. Tried H110 and Lil'Gun, but I like 1680 for consistancy.
Get around 4.5 fps SD at 1775 fps velocity and cloverleaf 3-shot groups @ 100yds. Sure will whack a deer.
Been wanting to try 200 gn. hard cast, but I can't figure out why.
Have fun,
Frank
