Age alone has little to do with it. How it is mounted does. And jusst because it was "professionally" mounted sure don't mean it was done RIGHT. I think more professionally mounted ones are done wrong than right some times.
This is VERY TRUE. I am FAR from even being in the same ballpark as a "professional", but I still trust myself more than anyone when it comes to setting up my hunting equipment.
7Mag...got a question for you. In the end of that chaotic moment in time...did your cousin kill a deer?
Yes he did...The sun was just breaking the horizon that Saturday morning, when I heard him ignite the primer in that old .270, I remember that buck, because he carried the antlers around for years in use as rattling horns...it was a pretty nice 9 pointer, but it had 2 broke points, nice bodied mature buck, he was, he shot him at around 150 yards if I remember correctly....that same afternoon he killed a doe...they were both in Kentucky...later on that year, while hunting in Tennessee, I remember helping him drag two more bucks out, but I believe he had already replaced the water-downed reworked stock by then...it was years ago, so I can not remember if he actually killed those two in Tennessee with the same old stock or not, regardless I am for sure he did it with that same old Remington 700 BDL .270 that his evil-harlot had attempted to wrap around the tree...He probally killed more Whitetail on top of that, but as I said, it has been years ago...
Also I would like to add that my whole family tried to get him to use another rifle and even offered to pool some money to buy him a new one, but nope, he was dead-set on getting his trusty .270 shooting again before the next morning, and with a little help, he did...
BTW I've had folks at my home range the night before deer season opened several times sighting in by flash light or head lights of their vehicle. Generally those who wait so long don't kill deer because that lack of preparation carries over to their hunting also.
I agree as far as "weekend warriors" and the altogether unprepared go, but sometimes accidents and turns of fate can set even the prepared in a bad situation.
Timmy's (ex)wife didn't break his rifle until the actual day before gun season, if he had had the same problem sooner, he would have fixed it sooner, and he would have not made any excuses for not doing so.
Especially if he had at least a 75 yard backyard, a few pillows, and a kitchen chair to brace his rifle on....
You don't have to have a "bench" and a 500 yard shooting range to sight in or test the accuracy of a rifle, it just helps....Again I highly recommend for you to do your best to fix your rifle now, and save your range trips for practice, not quality control.
Stay Safe. Happy Hunting/Shooting.
