Hi Saltlake58,
Hmmmmmmmm? 1/2" in scope height being negligible....... you are the fourth person suggesting Hi rings and in your case you even went 1/2" higher. Grateful for your insight.
Few years ago, Ted Bier went to RMAC with his scope elevated a couple inches above the bore line. Well, it looked like at least 6 inches. Not sure if that's a bit too high, but he shot well.
I also follow an Australian ELR shooter. His comments on scope height converted me to more comfort over lower scope height. Now, remember, this guy "Plinks" at 1200 yards, so take it all understanding it's a completely different end of the shooting sports:

Highly recommend following his channel if you are a technical type shooter. Excellent discussions that have much directly convertible into the airgun world.
