Hi guys,
I am using a high mount ( 1.5 inches), the distance between the center axis of mount and center axis of barrel is more than 2.3 inches.
Bushell professional boresight or magnet boresight could fit ? BSA bore sight ? or any laser boresight recommend?
Thanks in advance!

I use a Bushnell that has the bore spigot/lens/grid. Setup is fast and far closer to final zero that attempting to clamp the rifle still and mess about looking through the scope and down the bore, also much better for anything not conventional bolt action/sporter stock, you don't need line of sight through the bore.

I would skip all the lasers and other contraptions and just look through the barrel at an object and set your scope crosshairs on the same point. At that point you are on the paper at 100 yards. You can then get on the center in just a few shots ( last one I did was 7 shots, but many can do it in 3).

Same as above except I start at 50 yards.

I use a bright orange target on a white background but any high contrast color would work.

Pull the bolt and look through the barrel and get it centered on target then look through your scope and adjust until the crosshairs are centered on target.

I use a bipod and rear bag or clip into a tripod to do this. And I always end up on paper.

Save your money and do like mentioned above. The bore height doesn't mean anything. except a number to put in your ballistic program.

If you end up not on paper using the eye down the barrel method. Aim at each corner of the paper until you see the bullet on paper. Then measure from the aim point to bullet impact point with your reticle and adjust.

When I first started using this method I didn’t have as stable of a setup and skill and sometimes had to use the shoot at the corners but worst case was 5 shots to get on paper.

As (most) everyone else has said: no need to buy another gadget. Bore sighting works. It is exceedingly rare that I need more than a dozen rounds to go from first shot to fully zeroed.

I personally start the boresighting at 50 yards and adjust reticle to put shots 1/2 inch low and windage-centered. Then move to 100. I use pizza box lids - always an endless supply available :cool: - as a target (or target backer) with a 1- or 2-inch paster in the middle. Bore sighting at 100 for initial shots is fine if you have a big enough piece of paper.

As Rob said - scope height is just another number in the ballistic calculator. I use 1.26" rings on all my rifles.

Looks like you using bushnell professional boresight kit?

Yes, saves time, saves ammunition, can use it inside on the kitchen bench/table in air conditioning while I'm doing other things. Even as someone who bought a rural property specifically so I could zero and load test at home I think it's a great value purchase.

I just look through the barrel at a dot at 25 yards, dial scope about an inch under. Reset target to 100 yards, usually zero in 3 shots, then confirm with another three shots at another dot. Done, no fancy tools needed.

Congratulations?

You could hunt with a spear or by throwing rocks too?

This forum is bizarre, you are a poor and should just leave if you don't have 20k in one rifle/scope but if you use a tool which simplifies setup you should GTFO too?

In the last six months there have been at least two threads started about someone who had boresighters and where lost on getting to zero. I tried the silly things a couple of times. One sent a laser beam that was 10 inches to the left at 10 yrds. Another moved every time you touched the rifle. Just sighting through the barrel with the rifle tucked into a rest and adjusting the scope get me on target paper every time. Sighting it up at the neighbor’s car is fun as well😁.

You are the guy who doesn’t have one but because you think it’s easier you want one. Disregard all the posts trying to help you from wasting money and just look at the one who tells you what you want to hear. Tells me all I need to know. Have fun with your useless tool. Lol

My last time bore sighting - newly rebarreled 308 - 100 yards:

The first three rounds are the lower right.

Bore sighting ain't difficult, and using this method means one less piece of equipment to worry about.

This is like a bunch of people who can't integrate functions telling me how numerical analysis is easier. I literally dial the scope in on the cleaning vice in the living room, put the sighter back on the shelf, walk into the garage put the roller door up and smack the bisalloy plate a few times with the chronograph next to me. Saves wasting components. Factory ammunition is something like twice the price here. Can't bore sight a repeater or pump/lever easily either. I'd spend more time messing around securing the rifle to line of sight it than I do putting the spigot in. I'm not some muppet who takes the world bigget toolkit to the public range.

If its a gun that I cant look though the barrel to line it up then I use the Wheeler magnetic bore siter and it works pretty well.
Otherwise looking though the barrel to line it up on a target has always been more accurate for me

1. Staple up a big piece of tag board or use a huge piece of cardboard. Use sticky dots on it or just sharpie some circles.

2. Shoot at it

3. No mark? Zoom out scope a bunch. Shoot at berm/ground behind target. Notice puff of dust or snow or grass (hopefully…sometimes the ground is too wet or the snow is too hard to puff). Using reticle, notice correction and dial accordingly. Shoot at dirt again to confirm. Once close, goto #4.

4. Shoot at dot on tag board/cardboard. Dial correction etc

I skip the shorter ranges and go straight to the 100. Saves me time from hoofing my gun/gear. I don’t give a shit about ammo costs.

I care about time.
