Thread: Scope question

My brother recently re-barrelled a lee Enfield too 7x57R. It had an old 4 power Nikko striking on it that was rooted, so he upgraded to a Khales 3-9.

He's since tried a number of 3-9 varies on it, and all shoot 10 inch high with reticle wound as far down as they will go. Thats sitting in same mounts as the 4x was.

Anyone have any ideas on why the difference? Is it the fixed power or the magnification thats limiting the adjustment amount?
