Laser Boresighter

i agree, boresighters will help u find the paper. great shooting doesnt come natural. it takes time to learn how she's going to react and what ammo she likes. the best way i learned to sight in a rifle without using a bore sighter (and save some money) was to remove the bolt, or if it is a break open rifle where the butt drops away from the reciever and bolt is removed that way (if possible on the model u are getting) make sure the rifle is on a solid base and DO NOT TOUCH IT, that is important! (sand bags are good but rifle blocks are better) place the firearm on a sand bag so it is stable and if possible put another one on each side of it to block it from moving. look through the barrell from the reciever end and pick a point on the target. somewhere easy to see and away from other items on the paper. usually a grid of 4 dots that are no bigger than 1/2" on the paper is good. remember where that point is. now VERY gently adjust the scope or sights to the spot u see looking through the barrell. this does not work past 250-300m. if you move the rifle while adjusting it, start the process over. do this on a still day (no wind or weather) and in an area where you wont be disturbed. a good practice i learned when i was in the military, was to record everything, all sighiting ins, maintenance, and any problems with any component and/or any accessory used in the care, cleaning and maintenance of the piece. everything. record rounds fired and the typw of weather that day where u were how u shot, etc. this is good if you want to look at your progress as well as if you sell the rifle in down the road or if it is passed on to family, there is written history with it not just spoken so it make it that much more valuable in my opinion
Thanks very much for clearing that up for me guys
Thats a great tip Ike, thanks for taking the time to explain that. I probably wont be able to do that with my first rifle because it will most likely be a semi-auto .22lr but I could see that being useful when I move op to the real calibers. Also recording all the info at the range is a great idea too, didnt even think about that!
Yeah I'm going to do the same, good to have exact details too instead of guesstimations, especially with how many rounds you've fired!
i've got one of the rec-t-fire ones, as well as a bushnell grid/optical arboured one that i've had for years- the laser isn't NEAR BRIGHT ENOUGH even with all the lights out on the indoor range( 50 yds) AND their SPECIAL REFLECTIVE TARGET- in short a 140 dollar POS- it's downstairs somewhere in my junkpile b/c it's too sore a reminder of more money than brains- and that was after reading the article in the nfa mag as well- the grid type accomplishes the same thing abd you don't need any "special" conditions
the best way is still the old way- you take the gun to the range, with the loads you inend to use, set a target at about 25 yards or so- it's in your book where it says "first crosses line of sight at" - in the 308 it's 27- fire 3 rounds from a bench, sandbagged, see where that group is, then MOVE THE ELEVATION AND WINDAGE ON THE SCOPE over to the centre of that group- then try another group - it should be pretty close to centre- that's where you'll end up even with the boresight anyway- you can't "get away" without firing at least one group- if you've got a bolt, just remove the bolt and look through the barrel and move the scope adjustments so it coincides with the barrel
I have installed hundreds of scopes using the bushnell boresighter, good piece of gear for a gunshop, helps avoid frustration for customers. I don't own one though, I do a manual adjustment if possible then take her to the range and start close. The lasers are a waste of time IMO.

I'm so lost lol. I was looking at a Bushnell laser boresighter for just under $40 but I'm assuming thats a piece of crap? I think I'll just pay somebody to to at least get me on paper, I feel so helpless and confused :stfun00
Is this the one your talking about :

I myself am looking at buying one this weekend,as there about 4 of use who just got or are getting new guns this year. I was going to pay $10 to have it done, but a couple of shops I've talked to the wait time is up to 3 weeks or longer to get it done. I have to wait in line with all the repairs to get it done.
A bore sighter is handy but I usually take my first shot at 25 yards at a black dot of spray paint in the middle of a large piece of cardboard ( appliance box from the recycle bin)
Measure the difference between point of aim and impact and turn scope knobs accordingly.
If I don't have a big piece of cardboard I will usually shoot into the dirt berm at 25 yards and see where the dust flies then make a rough adjustment.

My laser boresighter is not a Bushnell, can't recall the make/model at the moment, but it mounts to the crown of the barrel magnetically, i.e. no arbor or other intrusion into the bore itself. It works well to get you close enough to center when sighting in, especially with a lever, semi- or other action type that is less convenient than a bolt gun for actual bore-sighting. I also find it very handy when switching scopes on a gun, which I find myself doing quite a bit. With a scope nicely sighted-in, I mount the laser and note where on the reticle the dot appears when sighting on my barn, 50 yards from my back door. Remove the old scope, mount the new one, compare the sight picture (reticle vs. red laser dot) and adjust as necessary to reproduce the same sight-in with the new scope. This is best done after dark, as you don't need to see anything through the scope other than the dot itself. This can easily get you to within 1 MOA at 100 yards, and can save a lot of time and ammo.
