i do that a good bit. Really helps with your shooting.I once read an article that said to go run until your heart and respiration rate were well elevated and then practice your shots at game. I've never done it but I could see it being beneficial.
Also, if 4" is all you can do at 100 then that's about as far as you should shoot at game. 300+ requires a tack driving rifle and a shooter capable of getting the most out of it from varying rests. Taking an improvised rest is also something that needs thinking about and practicing.
Very true, my quick zero on my 308 at 25 was off 8in to the right at 100 just the other dayon an aside.....
you cannot shoot a target at 25 yrds and know what your gun is doing much less capable of doing down range at any distance.
Yeah ....I can imagine those guys that shot at the Moon saying ....We really shouldn't be shooting beyond what we know for sure !!!!?
My longest "kill" on a deer was 414 yards measured .... I was hunting down a propane pipeline and had prior measured and flagged the yardage with flagging tape in both directions 500 yards each way ...
I use what is called Point Blank Range PBR( no not the other PBR) .... I use a 3" radius . ... meaning the bullet is never higher than 3" nor lower than 3" the line of sight LS( the straight line from your eye to the target). The maximum height (3" ) is 155 yards and lowest point is at 313 yards using the 115 grain Nosler BT ....PBR is 313 yards for this combo in my rifle.
I held the scope horizontal wire just above his back and easily squeezed the trigger ... he never moved out his tracks .... I knew he was beyond my PBR and needs some extra height ....
Yes I had shot many times with targets at various ranges between 200 and 400 yards so I had a real go idea of where my bullet would land ....I have a chronograph and knew the velocity ....I also knew the true ballistic Coefficient of the bullet (Brian Litz numbers) .... using JBM Calculator .....
IF you have ALL the needed information and use a good calculator like JBM ...... a shooter can place a bullet a lot closer on target ..... Guessing or not knowing .....is nothing but a shot in the wind .....
For someone who is not that familiar, charts will get you close but:
The absolute only way to know for sure what YOUR firearm will do with a certain bullet at a certain range with YOU squeezing the trigger is to shoot it.
