Best type of bore-sighter?
- Thread starter Futo Inu
- Start date
The other night, I used a laser boresighter for the first time. This was one that looked like a cartridge. You load it in the gun and when you close the action, the laser illuminates.
I went out at night to spotlight jackrabbits. I wasn't going to take a gun at all, I figured we could share a gun taking turns, but the guy I was going with thought it was important for me to bring my own so he volunteered to let me use one of those small "Colt" scopes on my AR. I boresighted and went to work. At about 25 yards, it shot maybe 5 inches high and windage was right on the money. I just put the horizontal crosshair on the base of the rabbit and never missed from there on out. I wouldn't trust the zero of a boresighter for any serious purpose, but for plinking a few jacks, what the heck ? And, I had to detach the scope and give it back at the end of the night, so it worked out fine.
This concept seems to me, to be the most accurate method of boresighting. There is no arbor to have misaligned; you are actually shining a light through your bore from one end to the other. And, you can shine it at whatever range you desire. I can't see why you couldn't shine it at a couple hundred yards and adjust your scope. True, for serious use you would also have to fire on paper, but I personally would like to be able to have it fairly close before using live ammo. It isn't nessessary and I have gotten along for years without it, but I would like to have one now that I have seen it in action.
One use of it is in actually mounting a scope. If you are using Burris Posi-align rings with inserts, you can determine what insert you need to line up the scope. If you are using Leupold rings, you can adjust the windage pretty close with the ring prior to leaving the house minimizing the BS you have to go through at the range.

Thanks, guys.
I realize it's just to get you on paper. That's what I need. In fact, Orlando, I'd be very curious to know what you do when there's no hole in the target at all.
SWFA, thanks, but Brownell's has it for $69.60, $20 more than what you said. I would be most appreciative if you can tell me where to get it for that price, or at least closer to your price than Brownell's.
Sam, what is the procedure, please, for the vic and eyeball method? Thanks.

Go do Wally world and buy a long sheet of paper wrapper. Have it cover the entire area and shoot at it. If there is no hole then the best way is to have someone stand behind you and tell where the bullet impacted.
If you wanted you can do a quick general zero in with one shot. Make sure the rifle is very stable, shoot one round. Move the cross hair to the hole that you just made. There is your zero. Not the best way but it is the fastest way I know of. It will at least get you the general impact area of the bullet.
I have used bore sighter before and they never help me zero my rifle.
One last reminder makes sure that the bore sighter is out of the gun barrel before firing. Write it down on the bore sighter so you don't forget.

I use a Bushnell collimeter kit to boresight and make sure I have the scope on straight.
Yes, you still have to do some fine scope adjustment at the range, but at least you know that when you put 4 clicks of "up" on the scope, the rounds are actually going "up" instead of somewhere diagnally.

SWFA is a scope business, he was quoting you his price on the item: http://www.swfa.com/
I have spent a lot of money with Chris.
The best way to get on paper if you don't have a boresighter is to start off close. If you don't hit the paper, move closer until you do. Then you can see where you are hitting. I almost always start off at 25 yards, fire a few shots and get it pretty close, then move back to 100 for the final setting. Over the years I have found that this saves time, ammo, and frustration over hopeing I will hit paper at 100 right off the bat.
"One last reminder makes sure that the bore sighter is out of the gun barrel before firing. "
Another beauty of the laser boresighter I was using; the laser itself is like a cartridge. It is chambered in the gun. It would be impossible to load a live cartridge with the laser in the chamber.

I'm with CR Sam on this one. Bore sights are a waste of cash IMO.
Go to Wal-Mart and spend $20 on a Case-Guard Gun Maintenance Center. Or get a decent gun vise. Both work great for holding a gun steady while cleaning or while sighting in.
Set up the gun in your vise and remove the bolt. Look down the barrel towards some distant object. I set up on my kitchen table and look down the street at my neighbor's mailbox. It's white and shows up easily in the barrel. Center the object in the barrel. Then without moving the gun (thus the need for a vise of some sort), align the crosshairs of your scope on the center of the object you viewed down the barrel.
Job done. I'm on paper at 100 every time.

Item #0015453500 LEUPOLD SCOPESMITH MAGNETIC BORESIGHTER $42.90
another way to sight in is to wait for night. Find a street light way out at 100-200 yd. If you can center it in the bore, and find it in the scope, you'll be good at least to 100yd (at least, that method worked for me). The lack of other visible objects has made this method real dependable for me.
I tried the dental mirror trick, but it was a real hassle with a 10/22, so I went to the Leupold Boresighter. Sure it's >$40, but I was ready to kill after the frustation with the Ruger. Now, all my boresighting is < 2 minutes and painless.

"what if there is no hole?"
I have used a laser bore site many times. Luckily I didn't spend my money on it. I still had to spend just as much time zeroing. It helps you not to have to make macro changes in site possition. If you don't hit the paper there are 2 things to do. 1. increase the size of the target or 2. decrease the distance to the target. I hope this helps.
