There are two requirements for these rifles in CMP matches, they have to be "as issued" and bayonts arn't authorized.
So if my rifles don't shoot right, I fix them, and fix them to keep them within the spirit and rules of the CMP GSM Games.
Seems to me that these two requirements are mutaully exclusive w/ regard to the Mosin 91/30..... and filing on the sight ladder is not in keeping with the spirit of the Games..... maybe fine w/ respect to the rules, but such "gaming the rules" is, at best, distasteful, to me.
"As issued" means just that. Mosins were issued with a bayonet, and were to be fired with it affixed.
As to "hitting high"..... I seem to recall reading somewhere that Russians were instructed to sight on the enemy's belt buckle.
