BSA Commercial No1 Mk3.

It is quite interesting that in comparison tests done at the time 0f the Mk111 being introduced the results showed little difference between the 'long rifle' and the 'short rifle'.
With the difference in FoM at 600 yards being about 1"

Some interesting take-aways from your post: I often wondered if the longer barrel provided a greater muzzle velocity but according to the comparison done the shorter barrel has a higher muzzle velocity. I wonder if handloading with a slower modern powder would give the longer barrel the nod. Next, the two rifles swap having the best FoM back and forth at the various ranges until they're a virtual tie at 1,700 yds. As you pointed out, not much difference between the two.

Some more comparisons - this was with the 'long rifle' vs the competition, and barrel life of the short rifle, along with speed of reloading.

You can see the British emphasis on musketry in that table. Even the "ordinarily trained" shooters had an excellent shots fired/hits ratio.
