Does any one have an opinion on either the Dixie Whitworth 45 cal(.451) or the Parker Hale Whitworth? ( .451 )I believe the Dixie is made by InvestArms. I am interested in a long range target rifle . The Whitworth seems to be the choice of many but I don't find many reviews. the ones you do find seem to indicate rather difficult loading with the standard Whitworth conical. Also does anyone have any experience with the Whitworth Hexagonal rifling or is the Henry rifling as good? Any advice is appreciated. Also :I plan on putting a green Mountain Sharpshooter barrel with a 1:24 twist on my Hawken. Do you think with a long Parker conical that this barrel will come close to matching the range of a Whitworth with the .451 conical if the BC of a 50 cal.conical is high enough or would the mass of a 50 cal give it to much of a rainbow trajectory? This would be for target only , so I'm not worried about ft pounds of energy
