My max with my DR in 500 Ne is 80 yards…I do not practice beyond that. You are using the marine method of trigger pull nothing wrong with that. I was taught by a former Seal who taught me let breath completely out no halfway stuff and squeeze. You are ready to go! Target grouping looks great!!!I am wholeheartedly against trigger squeezing. I break the trigger on command. Once I aquire the sight picture I am looking for it is one quick, I guess you could call it a "fast squeeze, but more like a "crush". I concentrate on not moving anything but my trigger finger and I "break" the shot. I don't like the squeeze it until it surprises you method because that does not work in an offhand situation or an unsteady situation where you may have to shoot in a "wobble". I will admit I don't usually "shoot in a wobble" at animals but I have found that breaking the trigger on command works better in general for field situations.
