Boresight, two lines that never meet
- Thread starter Redleg
- Start date
Different yet the same, Artillery talks internal external, and terminal ballistics cold barrel effects, the importance of boresight, we check every time we move, we zero except we call it registration, we group rounds taking into account dispersion range and lateral and we calibrate our guns (1981). We live to feed the guns direct or indirect, you will not see anyone run faster than an artilleryman hearing the words "Fire mission" We believe in preparing our position just in case we have to stay there until we have done the job and we move as fast as we can to the next position and will never turn down a fire mission I will stop to fire on or off the road for my brother. I account for the weather and when I snipe I have an observer except I use a round bigger than a 50 cal. I adjust but I hate to miss, I don't like to clean my barrel but love when I get a target hit. I take care of my projectile and my powder. We dial in corrections to our sights and keep data on prior engagements. Artillery has been using computers and ballistic apps(applications) for a while, the first computer ENIAC was conceived in the thick of World War II, as a tool to help artillerymen calculate the trajectories of shells.

I know I need to know more and share what I know so I can learn more from others and I have used the following as references for rifle and pistol marksmanship.

As you make clear here firing artillery is much more complex than shooting a rifle. As I'm sure bore-sighting for artillery is, too.
Bore-sighting a rifle has exactly zero to do with precision rifle shooting. In fact, bore-sighting isn't even necessary when zeroing a rifle.
The marine sniper manual has a section on boresighting, however, I will go with what you say.
I don't think I've ever bore sighted a rifle besides the eyeballing it. Certainly would never put a lot of time in it.
This manual says it is important

It's all so clear now.......
This TC that the Army is using mentions boresighting it dated 2016

Bore-sighting is a convenient way to start the zeroing process, but it is not necessary. I don't even own a laser bore sighter, so I don't do it on any rifle that's not a bolt or breach action.
It is rare that a new scope is not centered on it's adjustment range from the factory, so if you mount it properly it will almost always have you on paper at 25 yards and, once again, that's all you are looking for when bore-sighting a rifle. It's also a simple matter to center the adjustment on a scope yourself.
BTW, what does the Marine Sniper Manual say about bore-sighting? Is it any different than what I'm saying in general?
