I was out shooting my edge today and suddely couldnt even hit the target, I was trying to figure out why, when I noticed my scope was all the way forward in the rings, with the power adjust ring touching the rear scope ring, with some nice scuff marks on the sides where it had slid....

Why did that happen, and how can I keep it from happening again?

Its not the stock scope btw, its a simmons whitetake classic 6.5-20x50, so Its quite a bit bigger than the one that came with the gun, but I am using the rings that came with the gun...

Was shooting handloads when he happend, sierra 150gr SP over 43.3 grains of varget.
