How close is "too close" when it comes to adequate scope clearance. My NF scope in seekins rings on a 20 moa ramp has only a .025 gap with a new 284 barrel. I might gain just a little if I move the front ring back 1 slot but that's about it. The seekins rings are great but their .97" (high) is a tad too low IMO. I did run about 20 rounds through this set-up on a 50'ish temp day and it shot great but I'm thinking that little of clearance might be a problem when she hits the 90's. Hopefully someone will tell me .025 is OK since I got it dialed in and don't want to mess with it!! Eric in DL
