That's roughly equivalent to the .44 Mag and I intend to make the targets "iffy" to score with the .44 Mag. Jakashh references 340-grain bullets out of the .44 Mag and that's what it would take to start to be competitive. AFAIK, the .45 Win Mag is usually used to just get higher velocities from 230-260 grain bullets.
A Wildey in .45 Win Mag would be very well-suited to bring home one of the trophies - just not the overall match winner trophy.
Thanks for the reply Ben!
