bore sighting?
 
Can I change scopes on my slug guns, rifles and rimfires and crossbow and sight them in on my bench? I see a bore sighter at walmart for $40 would that help? I really need to get close by that I mean within a foot and then take them to the range.

I wanna fool with scopes and rifles and changing optics will be part of my hobby.I bought a Mueller 2x7x40 with red dot and I'd love to use it on my croosbow, my shotgun, cause it it really great on my ML.

thx for your help

RE: bore sighting?
 
Are you planning on using the same scope for multiple weapons? If so, you're setting yourself up for more trouble than it's worth. I'd buy a scope for each gun/crossbow so you can sight in once each and be done with it. If you switch the same scope out between different guns the POI will change each time you change the scope, which means that you'll be doing nothing but sighting the gun in all the time. A boresighter is designed for two reasons, to allow a gunsmith to mount a scope so that the scope will be as close to boresighted as possible with the turrets set to center, and to get the rifle on paper at 50-100 yards. A boresighter will NOT sight the gun in to an acceptable level for hunting. You'll hit the target, but beyond that you MUST take the time to sight in with live fire.

I totally agree . You will burn more ammo that what it is worth. Put an optic on each weapon.

Bore scopes are basically worthless for your purpose due to they change POI upwards of 6MOA or more by the changing position everytime you put the stem in the barrel.

The laser chambering would be ok if they would put the laser in a fireformed case. But I have seen them work well either.

FWIW I just look down the bore on rifles(hopefully not a semi you have) and keep centering bore and crosshairs on target. If you play with it and fine tune it for about 10 min or so I've always been within a foot of the center. Works better than a bore sighter.

I'd assume the laser insert does fairly well also. But don't have one or use one.

I use a boresighter and find that I am almost always within 6 inches of center at 100 yards in about a minute.

You won't regret buying that boresighter. I have two, one that uses barrel spuds for the serious work and a magnetic one to pack along on hunting trips just in case. Both do the job I intended for them and are big time and ammo savers. You might also consider a mount/ring alignment tool of some sort, I was really surprised how many reciever mounted mounts and rings don't line up on factory rifles.

Whats the difference in doing that and just shooting 25 yards one shot and adjusting to -.5 to -1.2"? Then shooting 100yards and doing one more adjustment?

But to do that, your scope height needs to be the exact same on all rifles or you have to remember the zero on the collimator?

Sorry guys, I am just fed up with my boresighters right now. I guess looking back at hunting season, and seeing all the "one shot a year guys" come in and shooting a new 700 they got at bass pro, and wondering why they ain't cutting x's at 100 yards got me aggriavated.

All of my rifles are built on 700 actions and all use the same leupold mounts and medium rings.After learning the grid on the individual boresighter,you can always at least be on the paper at 100 yards.I don't waste my time shooting at 25 yards.

You mean to tell me out of all those rifles you got, all are 700's. No model 70s, rugers, brownings, sakos, or tikka? None? Well that explains your success with it. I think this feller walks a different path however

slug guns, rifles and rimfires and crossbow

Where I live I don't have access to ranges with such short shooting distances, only 50, 100,and 200yd on public ranges owned by the state game commission. To set up a target at any other distance can result in a fine. You can walk your POI in like you said but I use the boresighter to make my adjustments that's where the time and ammo savings come in to it for me. If you don't want to use a boresighter then don't but I will continue to use mine.

I think the guy wants to do something a tad different. I was trying to explain to him the difficulties with what he wants to do, and why it really wouldn't benefit him much and other alternatives.

Congradulations on you and your boresighter. Seems you all make a good couple.

I have owned winchester,brownings,rugers,howas,sako's,weatherby 's,smith&wessons,ithacas and parker hale.I still own my first rifle which is a 1950 model 94 but it has only been used once in over 20 years and that was to kill a cougar at 30 feet.All of my current hunting,varmint and target rifles are built on 700 actions.

I have to agree with Drift. More trouble than it's worth. Buy a scope for each setup.

I certainly do agree with that point although a boresighter will still be useful for sighting in those scopres.
