Hello i have a question on mounting a scope. I have a heavy barrel 6x284 that's fluted. Warren bases with Burris XTR rings 30mm with a NF 3.5-15x50. with the scope mounted I can see daylight between the barrel and scope bell. But i cant get a piece of note book paper threw it. Is this OK since i can see light? If not i have some thin brass shim sheets can i shim between the scope and rings? Would this be OK or what should i do? I'm kind of wondering if i did shim if the scope would hold solid in the mount being shimmed. Need you guys advice i just like it as close as i can get its just more comfortable shooting for me any ways. Thanks for you time
