LB: your comment about killing power being a function of large meplat is exactly what slugs are all about.
Taylor Knock Out tends to favor larger calibers simply because the frontal area of the projectile dumps it's energy faster that smaller faster boolits. Bus vs Porsche.
A 12 ga 1 oz Slug 440 gr at 1300 fps has a TKO of 60 and a muzzle energy of @1600 ftlbs.
A 12 ga 1 1/8 oz slug (490 gr) at 1600 fps has a TKO of 84 and a muzzle energy of @2850 ftlbs.
A.458 Win Mag 500 gr at 2150 fps has a TKO of 70 but muzzle energy of @5150 ftlbs.
The frontal area delivers the TKO or Knock Down Power, but the velocity and smaller dia delivers the penetration.
The Brenneke Slugs will.............................................. .................................................. .................................................. .................................................. .................................................. .................................................. .................................................. .....l;;l; take down any Bear (Cat typing!)
But I think so will any of our attempts at reinventing the wheel.
We have the power and these threads are helping us understand that power!
New Idea! how about one of your Lee Slugs with the Felt wad attached shoved down into a cut down hull and roll crimped?
Short Brenneke?
My mind drifts along.
