Spanky,
Get us a range report when it comes in. I'll be interested to see how it does. I stumbled across this company, they make heavy duty .410 slugs designed to be shot out of their own custom rifled slug barrel for a T/C contender. If you scroll down to the bottom of this page it looks like they have a rifled .410 slug barrel in the works for our NEF's -
http://hoeningbigboresouth.com/HBBS_News.htmlIf you surf around the site they give a ballistics table which is rather impressive for a .410 slug:
HBBS 410 Uncrimped Heavy Load 375 gr Slug, BC = 0.214, 100yd. zero Range (yards) Muzzle 50 100 200Velocity (fps) 1500 1366 1249 1078
Energy (ft.-lb.) 1873 1553 1298 967
Trajectory (in.) -1.5 1.6 0 -20.8
With that setup the .410 actually becomes a legitimate 100 yard deer round as strange as that sounds.
