M1917 Stock question/issue

[Patrick Chadwick]

"Never change a winning team" also applies to that tricky mix of wood and metal known as a rifle.

If the present grouping is in the 2-3 MOA range, you can reckon that about 1MOA of variation is the rifle/ammo combination (with optimized ammo), 1MOA is the limitation of aiming with a blade foresight, and 1MOA is your PWF or Personal Wobble Factor. So it will be difficult to see if any alterations produce a statistically significant improvement unless you get a good scope fitted and shoot from a rest. My Eddy also groups about 3MOA with service sights, but just about manages 1MOA with scope and rest.

I found that the biggest improvement in grouping was achieved by carefully selecting the powder charge to suit the resonance of the long barrel. Maybe this will help -

Post#8 - group size halved by selecting powder charge.

Stretching an analogy to the extreme: don't pull up the plant to see how the roots are growing - try varying the quantity of fertilizer (nitro)!
