Is it a high comb or low? I have a 3.5-10x40 Leupold on a low comb with low rings that work. While close to the bolt handle I can still work the action without a problem. I used medium rings for the high comb with 1" scope and I believe mediums for the 30mm scope I had on another high comb. I have a 1.5-4x Bushnell on mine Mod 88 .358 Win I use it for brush and timber hunting..
