I have a .62 English Sporter in the pipeline with Steve Zihn, w/ 34" Ed Rayl straight taper barrel. I'm trying for about 9 lbs finished weight. I may indeed hunt elk w/ it, but I want something that will handle LARGE hogs, as these are my primary target.
My .66 Christian Springs is sighted for 75 yards w/ a .658" PRB, and 150 gr. (~5 drams) of Goex 2F. I suspect it will whomp 'em too. 8)
