Easy way to boresight scope
 

Hi everyone,

I just got a replacement scope for my CVA inline. My old scope was a Bushnell that I referred to as my "no eye relief scope". I came back from my last range session looking like I was in a bar fight - bruised nose & black eye. My wife refused to let me shoot "that thing" again until I fixed the problem, so guess what? - Excuse to buy a new scope:)

So I found a Simmons Master Series ProDiamond scope on clearance at Walmart for $40 that has 4" of eye relief. My question is, what is an easy & fast way to boresight the scope to get you on the paper at 100 yards?

Thanks in advance.

Easiet way I know is to set up a bench that's solid and the gun solid and try to put first shot on the paper at 15-20 yards. If you are on the target keep the gun stationary and move the elevation and windage adjustments to center the crosshairs on the hole. It's easier with two guys. One keeps the gun steady the other turns the adjustments. This puts you right on. Fine adjustment for range is easier and you won't be out a lot of powder and ball and have a lot of frustration. It's called one shot centering and it works.

You can take out the plug and look through the barrel trying to sight something...then see were your scope is aiming. It is a rough zero, but it worked on my .300 win mag. We learned that in the Army to rough bore sight the tanks.

I take a cardboard box and cut a V on the two opposite sides when I did not own an fancy gun rest. Put the rifle in those V's and remove the breech plug. Now I like to line up at 13 yards, on a door. A hallway works great for that. Put a flashlight on that door if you have to. Remove the breech plug and without touching the rifle, look through the barrel at the door. If you can aim it at a door knob ... all fine and good. If not, take some masking tape (so you don't hurt the door paint or finish) a put that tape on the door in the center of where you see through that breech plug.

Then carefully look through the scope and start to make adjustments to that tape. After you have the two lined up. Go to the range and shoot at 13 yards and shoot the first shot, then move to the bullet hole. Shoot a couple and they should stack.

This should put you very close at 100 yards by the way. Although if you mount the scope properly, at 13 yards you should be pretty close.

It is very easy to get on paper at 25 yards. Then you can zero the gun in and move the targetto 100 yards. Take the breech plug out of your gun and sight through the barrelat the 25 yard target. Adjust the scope until the crosshairsare onthe bullseye.

Alaser boresighterhas saved me a lot of ammo. I boresight the gun with the laser at 25 feet on a 1" target.The gun is always on the paper at 50 yards.

There are several ways that I have used at different times the two I like best are pull the breach plug insert laser pointer [just a regular pointer ] set up a target at 20 yds move the cross hair on to the spot this works best at dusk or after dark. The other way is very similar with a pen light setting at 20 yds. You can lock the rifle down in a rifle vise or pad it and use a regular portable vise and set your target up at 20 yds and move it so the bore centers then move your cross hairs to center. Lee

Thanks for all the replies- I've done a rough bore-sighting looking by removing the breech plug and eyeballing a target, then adjusting the crosshairs. I won't make it to the range for a week or two, but I'll start out at 25 yards and move out from there. Thanks!
