bore sight help?
I am going to get a new scope for my remington 870 slug gun. I don't want to spend a small fortune getting it sighted in,and am thinking about getting a bore sighter to make it easier. I have never used one before,can someone recommend a user friendly one that won't break the bank? I have seen the ones at cabela's that look like a shotgun shell and shine a red light down the barrel,will this work? http://www.cabelas.com/cabelas/en/te...exId=cat200006 I am not going to be using it very much,so i don't see the need to spend over $200 on one that doesn't see much use. thanks for the advice!!

I suppose that would work.
In all my years of shooting, I've never used a boresighter to get onto a target.
When I can see through the bore, I've put a 'dot' on the wall and centered the bore on that dot, then, aligned the scope to match the 'dot'.
First shot (at 25 yards) is pretty darned close. Getting 'on the bullseye' at 25 yards, will normally put you (with a rifle) about 1-1/2 to 2" high at 100 yards.
I'm not so sure with a slug gun. (Arcs like a rainbow or an artillary round!!!)
I've been doing that routine for over 30 years, I suppose.
If I can see down the bore, a small mirror works (like a dentist's mirror).

I've never used a bore sighter either. Always use blueovals method. But as already said, doesn't work well with blind breech guns.
Here is what I would do Ben.
Setup your target at about 25 yards, or whatever distance you are reasonably sure you will hit the target.
Fire one round. Note where it hit your target.
Lock the gun down in a rest or sandbags, with the sights aligned on the original bullseye.
While holding the gun solid, adjust the sights until they are aimed at that first round point of impact.
Fire a second round to verify.
That will do a better job than a bore sight, with only 2 rounds expended.
Either way, you'll need more rounds to finish the job at greater distance.

Option 1. - On the 870, rack the slide back, and leave the bolt open.
Use a small mirror to see down the barrel.
Option 2. - On the 870, IF the scope is barrel mounted (cantilever mount), remove the barrel and scope and place in a padded vise. Proceed as described in my first post.

Like Keith said, Use a small mirror in the chamber.............Some are available from gunshops that have a small light as a part of the mirror, and are made specifically for this application. A good rest is essential for this too, wobbling around and trying to boresight are frustrating as ****!
