Never had this happen before on the range

[Randy Bohannon]

I grew up with a bb gun and eventually pellet guns and learned to kill things with their rudimentary iron sights.We could see the trajectory of the bb and get pretty good at killing quail in the trees in the creek bottoms.I could alway shoot well ,throw rocks, sling shots, archery and guns.I was never more tickled than learning I could shoot amazingly well with the BPCR's and really good sights.
Your friends experience reminds me of getting my Son started with scopes. He was doing the leaning over the stock trying look with his left eye, he's right handed L eye dominate. Bought him left handed stuff he does fine now.
