Lol still delusional.
Did I say that? More deflection loser. Still can't answer the question.
What does the elbow postion have to do with the potential of a gun? Just because you say it is clumsy without ever holding a gun doesn't make it true. You are digging a rather deep hole.
Btw tucking in hard with any rifle is uncomfortable. I shoot AR's and semi auto rifles with a stock at about a 30 degree elbow angle. I literally just tried it and there is little difference in comfort between them. I find that elbow postion naturally comfortable for me.
The reason the elbow out is a thing is because you can seat the rifle better into your shoulder with any rifle. Not just a rifle with a stock. This is observable with your hand. Put your off hand where the butt would meet at your shoulder. Now move your grip hands elbow in and out. The Higher up the more of a pocket is created. It is a precision hold. Also by doing that more recoil goes into your peck vs your shoulder. So depending on what the type of shooting your are doing with any rifle your elbow angle should adjust for the situation.
