So I got out to the range today to zero a couple LE No4’s I picked up. Both are 1943 Longbranch MkI*’s. The first rifle was dead on at 25meters... For a 400meter zero. I know that the elevation is set by the front sight post but I’m horrible at math, can anyone tell me which sight I need to get for a proper 200meter zero?

The second rifle keyholed all over the place. I’ve seen this before with AK’s but never experienced it with LE’s and am looking for possibilities of what might be causing it. The barrel looks ok but I haven’t run a borescope down it yet to really get a good look. The stock is sloppy loose so I wonder if that might have caused it, but it strikes me as unlikely.

Both rifles were shot with Hornady 174gr Match ammo.

Can anyone help me out?
