Thank you, Surpmil, for that.
I am tired enough of being called a liar when I talk about the performance of a good Ross Rifle that I keep a box loaded. Anyone calls me a liar, I just invite them to the range. It is surprising how many back off when confronted with the possibility that they could be wrong... and the dangerous old POS rifle just MIGHT shoot better with century-old iron sights than their spiffy new Remchester does with its 24x scope.
One thing. Army doctrine called for aiming with the whole width of the blade of the front sight. That's fine and well for big targets. But the CORNER of the front-sight blade is a lot smaller.... and the Ross has an adjustable rear sight. So what you can do is put the rear-sight aperture OUT about 2 minutes and aim with the upper-right-hand corner of the front-sight blade. This will REALLY tighten things up, especially if your eyes are getting a bit old (as mine).
BTW, same technique works on a Garand, which has pretty decent sights for a battle rifle.
For tightest groups possible, try this technique while aiming at the bottom-left-hand corner of a 4-inch BLACK aiming-square at 100, or a 6- to 8-inch square at 200. Nice, big, easy to see target... nice, big, easy to see sight blade.... teeny, tiny, itty-bitty little groups if the rifle, ammo and shooter all are working together properly.
Carry along a Bic lighter; smoked sights shoot best.
Give it a try. Seriously. Works.
