Amen to it's the first shot that counts. And that is from a cold bore. I crack up when I go to some of the sporting goods stores now - and the gun shows - and it's all about "Tactical". Sure - if you are going to pray and spray something fairly close - that's great- but get beyond a short distance - and you better be zeroed in.
And all the other factors mentioned come into play when hunting - and not comfortably "resting" at a range.
I got to get out shooting again. Been fishing a lot the past few years - even caught a nice Marlin (125 lbs) down in Cabo - but now have to join up again at one of the shooting clubs and start practicing. The longest - easy to join club/range - I found years ago was about 300 yards down at the South Bay Rod and Gun Club (30 miles or so) - but there is/was a 1,000 facility/yard club up north - Escondido - also about 30 plus miles - so have to check that out again.
Again, really appreciate the advice.
And as for my buddy here in SD selling his beloved 7 Mag - well I think it was a couple of things. He had hurt his shouder at work - when he was involved in Security at the Airport and helped one of the baggage handlers hoist a heavy suitcase and wrenched his shoulder - and I think he was also out of work for a spell and needed some coin - so he sold the 7 Mag - a sweet shooting Ruger that his friend - a former sniper for hire type - had really buffed up for him. He still has his 1/2" shooting .308 - and a couple of his pistols - and at one time - could pretty much shoot with anyone with a .45. whatnot - where he was a better shot than with a rifle - but he ain't bad at all with a rifle. That's back in the days when he was on a police force and had access to mucho handgun ammo/practice. His backup/ankle pistol was a .44 special - so he was rarely "outgunned".
