50%
Sounds like a simple challenge, but if you are not an expert, we are getting set up for some disappointment. LOL
I really wanna try this challenge, but really with low expectations. I'd guess 50%. I know I'll be close to hitting it but 100%.... Dang.
I watched a couple you tube videos and It's really been humbling to some folks.
Really when you think about it, is it really possible for the average shooter. I mean that I have a 1 moa rifle. So that means at best I can shot a 6" group with this rifle at 600 yards. What's a milk jug 6 or 8"...????? So if I do everything perfect then MAYBE I could hit it every time. Throw in the wind, ranging, dialing, barrel heating up, perfect rest, did I mention wind, elevation, earth rotation, spin drift, perfect loads and what else could go wrong.
Not saying it can't be done, but I'd like to shake your hand if you can do it.
I guess my opinion to best describe long range shooting would be to overcome 100 variables 1 time is amazing. To overcome 100 variables twice is 1000 times harder. Each time more is multiplied by 1000. So depending on your ability, X amount of times is impossible. I will shoot every shot thinking I will be on target but reality is there is a lot that can go wrong.
