I was just wondering if shooting from a stand with a gun would throw off my sight. I just got a Reminton 870 Mag Deer Gun with a Red Dot Scope. I have been shooting Remingtons 3" Sabots out of the gun. Sighted in at 85 yards and I can do alright...shot around 2" of the bullseye.
Anyways this friday I got 3 shots on does, and missed everytime. The first doe I shot at, it just barely grazed her front leg right under her vitals...it was about 2" away from being a dead deer. I saw her come out that afternoon but never got another shot. The second two shots just totally missed her.

So I was just wondering if when I shoot from a stand if I am lowering my arm at the shoulder or something, throwing off that red dot making me shoot low...has anybody else had any experience with this sight? I am thinking about switching to a better scope for next season. I was just wondering if my thinking made any sense to you guys.
Sorry for the rambling post, I wasn't exactly the best English Student
Thanks.
