Tinker - my own .14 bore, .684" pure lead ball of 484gr. with 6 drams (165gr.) ran an average of 1,550fps. With the point blank sight low, and the front bead down on the barrel, this gave me a point blank range of 120yds. with a 100yd zero. I had to go way over 200gr. of powder to achieve 1,700fps. so I settled on 165gr 2F (6 drams) as being an accurate, full charge hunting load.
: Impacts at 100yds on Moose, were a sight to see. The moose shuddering on impact, and collapsing inwards, it seemed. "Taking his wind out" was one of Forsyth's phrases. This happend time and time again. I surely do love the 14 bore. Forsyth was spot-on in his recommending this gauge as an all-round bore size for large game. It is accurate, has resonable recoil for a large game rifle and is very effective on the game.
