No.4 barrel support vs sporter?

[CINDERS]

The firearms manufacturers like Enfield, BSA, Savage ect had more resources and smart people doing the math and the tuning of these things far better than we mere mortals can do so what you may think is something new they would have tried and discarded for a reason.
The SMLE and its derivatives were not designed to be a pin point 1/2 moa weapon rather a weapon that was reasonably effective, reliable and could bash out the rounds as that Sgt did in the very early 1900's think it was 38 consecutive bulls eyes at 300yds in 1 minute now that is a feat of arms.
(And no I do not know how big the bull was)
