What shoots better A No1 Range Rifle, or the same rifle except with woodwork

[CINDERS]

Gads what a question that's like two identical MGB's and the drivers doing different things to them and ones tweaking getting the little bit extra ooompf, Percy Pavey & James Sweet used Mk III's but they could have any number of personal tweaks I think there was a Motty barrel floating around somewhere there as well.
A persons mind set, personal training whos feeling better on the day it is as much the shooter as the weapon, but the only leveller was the ammo I think as they had to use Ball ammo correct me if I am incorrect here guys..

Others may want to expand on this question you have posed............
