Thanks for the detailed advice and experience everyone. Joining a shooting club is a tad hard for me since I'm out a ways from a range and if I have to drive there at night then I'll probably nail at least one roo. However, I have all the room on the farm I work on to practice (Which is why I was hoping for advice about things that I can do on my own), but even then I could probably find some good shooters who would be willing to help me out; Next best I reckon.
My flinch seems to occur when I pick up anything bigger than a .22 or .22 Hornet. I can bang away all day on a .22 and never flinch but that is not impressive. However, for many years a .22 has just been a crow gun to me which all it has to do is hit a crow at 50 yards and thats it, I've never used one simply to push for as much accuracy as I can and it is something I will try now that it has been mentioned.
No4MkIT, I know of the trick with blackening front sights but I did not know that they should be the point of focus over the target, but I suppose focusing on the sights more could also take away the stress of "This is the target and I have to hit it" of being fixated on it. Also I used to shoot with the 'surprise' technique' as you have mentioned but I thought it was always just me being unexperienced so I tried other things that never worked, hence I am asking here haha. Yeah standing shooting I am half decent at but I never thought much about such as thing as Natural Point of Aim but it makes a lot of sense (Natural things and concepts like this are exactly what I was after).
Before this my knowledge of accurate shooting was limited to: "Do every shot the same way every time" which was great unless I was up the paddock and had to adapt to a new position. You guys have given me some basics and concepts so I guess I have to go out and practice them now, and meet shooters who don't mind sharing their secrets haha. Anymore advice is also welcome. Thanks everyone.
