It's a thing
You are trying to get your field target build to be at a "certain" comfortable weight to shoulder and handle in the sticks and especially in the forced lanes.... up until, It gets so light, that the big ol scope on top becomes "too" heavy and you reach the Tipping Point.
Also known as that balance point where the gun might want to just flop over from vertical to horizontal while your addressing the lane.
I recently helped a guy set up a .177 Blackwolf HFT rig in the very light carbon painted wood? stock. He's 80 years young and needed or wanted a lightweight set up.
Goal <9.5 lbs scoped.
The only FT gun i have ever set up, besides the Blackwolf that came close to this desired weight was the Crosman HFT Challenger when scoped with a Sightron S-Tac 4-20x50. This same scope on the Blackwolf yielded an all in weight of just < 10 lbs. Ahhhhh!
But, and here lay the problem.... once you have the right airgun, and you think you have the right scope, it needs to be a scope that works for YOUR eyes.
The S-Tac was a no go for this older gentleman so we played with several Athlons, and Nightforce variations that he liked the reticle on.
Every time we found the perfect for him reticle, it was within a scope that once mounted was (to me and him) too heavy and made the gun tippy in the sticks or very prone to canting.
Grrr, says I....
I think he will have to deal with buying a heavier stock, or using a scope with a reticle not to his absolute liking or finding a way to put more weight below the center of gravity and maybe slightly aft of the trigger guard to stay away from the tipping point.
Thoughts..... Compromise required me thinks?
