Can some one give me a good comparison between these 2 rifles? Will they both shot the same conical bullet? I want to get one of these, but I don't want to mold my own bullets. I've read that the specialized .451 bullets purchased at muzzleloading-bullets.com work great in the Mortimer Witworth and the price for 50 is very reasonable. Will these bullets also work in the Gibbs also? Thank you in advance!
 
Yes. Both 45 fast twist for conicals.
I believe the Mortimer is 1:21, Gibbs 1:18 twist.
Mortimer Whitworth is not a Hex bore, only the name Whitworth is used - this rifle was made for International shooting competition ‘Whitworh match’ to 200yds.

Thanks for the reply,!
 
The Mortimer-Whitworth is primarily intended as a short range rifle. 'Whitworth' in this case is derived from the name of the MLAIC 100m prone match (all MLAIC short range events are named). There's several versions of the Gibbs made now, including one with the same twist as the Mortimer for short range shooting. The sights on the Mortimer are only suitable for short range.

I'm not familiar with the bullet company you mention, but a quick look at their web site shows grease grooved bullets .45 cal and 495 grains. They should perform well in each rifle (assuming good fit to the bore) at short / mid range - but most shooting the Gibbs (long range rifle) will be using bullets 530 grains+.
