Depends on the rifle. You'd have to change them according to ammo and fall of shot.

You could bore sight it: remove the bolt, set the rear sight to 200 yds, prop the rifle on a rest and look at a distant object through the barrel. Then lift your eye and look through the sights - the same distant object should now be in your sights.

Your question is unanswerable.............. Surely, the ONLY answer is a rhetorical statement. That is is to shoot the bloody thing at 100 yards and THEN ask the Q after then telling us where the MPI is in relation to the point of aim. Or am I missing something in the reading? Is it my old age?

[RobD]

Peter, I assume he has no sight blade in it and wants to know what the average starting height of a front sight blade would be. Is that a fair question? Or was there no "starting blade" when the rifles were zero'd?

[Peter Laidler]

In my experience, you'd HAVE to have a blade of some sort to even start the process. I mean......., where would you point the rifle - apart from '.....at the target somewhere'. Even using the old telescope layer that we used to use as an optro-mechanical method from the Enfield Rest at Base Workshops needed a blade to start the process. It's an unanswerable to me.

Try a +.045 then let us know where it's hitting.

........ or +.090" as you can only go lower. If you need something higher, you're stuffed!
