Anybody pursued elk with slugs before? If so what gauge, shell length, and slug weight have you used?
I never have hunted with slugs for anything, but am intrigued by the knock down power at close range. I'm thinking a 12 gauge, with 1 ounce slugs, 2 3/4 shells inside of 40 yards would be sufficient (muzzle velocity is around 1700fps). From a ballistics standpoint I think this would be similar to muzzleloading (in bullet mass, shot distance, muzzle velocities, and ballistic coefficient, in other words "big round lead balls"), although I have not used a muzzleloader before either.
Just for kicks I ran a few numbers at the muzzle to get an idea of kinetic energy and momentum.
KE 2814 (ft*lb)
MV 106 (ft*lb/s)
In this thread from awhile back I calculated various KE/MV for a 30-06 and 300 weatherby. As you can see the kinetic energy is down some from the 30-06 and definitely from the 300 weatherby (w/ 180 grain bullets). The slugs have a thunderous amount of momentum though, owing to the 438 grain slug. Those big fat slugs will lose speed fast, so I'm guessing that anything beyond 40 yards would be too risky. Anybody know of ballistic data for this on-line?
Anybody have any thoughts?
