Due to the twist-drill boring used even today, the bore is a long spiral, even in a top-quality "straight" barrel.
This is why aligning the reamer to the throat produces reliably precise barrels, while aligning the reamer to the muzzle, like running between centers in the olden days, is...
Unless there is something WRONG with the barrel: ^^ This ^^
We have proved this time and again, where a 'cold shooter' blows the first shot, but if you put a shooter that has warmed up on a cold rifle, somehow that first shot goes into the group. About every 3rd or 4th class we'd have a...
LOL, no, but you might die if your request for vital aid can't make it over some clueless individual playing with their radio.
No one will. The rules DO allow for emergency use on normally unauthorized frequencies, but DIRE emergencies, literally life & death. No one expects anyone to hump...
No harm "just to listen", because just listening doesn't disrupt potential emergency commo by skilled operators.
It is good to have a backup plan. The problem with this specific approach is that people who will be legitimately trying to communicate using accepted procedures will be interfered...

Might I suggest a rectangular block shape for your next example? Easier to reach the punches and also more shelf-friendly.
You might also vary the depth of the holes - deeper holes in front, more shallow holes in back.
50 yards is kind close to alter anything, but for longer ranges, I modify sight alignment by bringing the front sight blade up above the top of the rear sight. You can learn to judge pretty easily. The boys that used to work the Allegheny Sniper Challenge shoot their iron-sighted 1911s out to...
