I have a remington 700 sps in 308 it has a Nikon 4x12 monarch(came on it) its a decent enough scope. What I'm wondering, is there anyway to mount another optic on top of that scope. I want to have the second scope for my sub-sonic loads. I thought I had a good hold position with the current Nikon, but missed a hog at 58 yards. I knew where to hold for 50 yards, not 58. Would not have thought 8 yards could make that big a difference, but I guess it did. Any ideas or thoughts would be much appreciated. I will post this on predator masters also... thanks in advance- pig
