Title: Laser Bore Sighters
Post by: Screaminreelz on June 10, 2009, 05:35:12 PM: I'm thinking about getting one to save a few bucks on shells. Have any of you ever used them and if so what are the pros and cons? Also best brands seem to be Sightmark and NC Star true or false?

Post by: sisu on July 10, 2009, 09:24:31 AM: I got a question on those laser bore sights. Which ones do you guys own? I tried one that an acquaintance owns and it was off by 6 inches after he sighted it in and I went to the range. I was not very impressed with it, but I have to add this, he was not well versed in it's use and kept fumbling around with the thing and my rifle.
Anyway any suggestions on which one to buy or how much money is enough to spend on it will be gladly accepted.

Post by: jackelope on July 10, 2009, 12:08:43 PM: 6" off isn't too bad a bore sight job...seems that is a pretty good job to me.
it's for bore sighting, not for zero-ing.
i have one but honestly have never used it...can't remember the brand name...might be branded with cabela's name on it and it's green.

Nothing is designed to have the same trajectory as a bullet, rather, the beam represents the point of impact at a known distance. IE: Your bullet will travel thru your scopes line of sight twice, once on its way up, once on its way down.... Since my rifle is sighted in at 250yards for point of impact, then I can either allow the lazer to point where that impact is a 250, and adjust the scope crosshairs to that spot. But, since 250 is a long way for most lazers to be visible in daylight (atleast the ones I have used...) I prefer to use 100yards or less to anticipate where the round should be traveling. This can be done at home prior to range time, and is quite simple at the range.

One of the primary cautions is to be sure and remove any part of the device you place in the end of the bore before you fire at the target. :( You might laugh, but more than one gun has been ruined by this short mental lapse.......... It is also quite hard on the bore sighter.

The more powerful the laser the brighter and straighter the beam of collumnaited light - which is what laser light is. Powerful lasers have been beamed to the moon and reflected off a tiny mirror left there by astronauts, a distance of 500,000 miles there and back, to nearly the exact same spot as the laser originated.

It stands to reason that, even a low-powered laser, within 100 yards, will give you a rough idea as to the relationship between the cross hairs of your scope and your bullet impact on a paper target. At 100 yards a low-powered red laser will appear as large as a softball. If your scope cross hairs are accurately alligned with the target center you should be pretty close to on-target when you fire your bullet.

A higher powered green laser (more expensive) will appear as small as a golf ball and a little brighter. This is a more accurate way to sight in a scope but the low powered lasers work pretty well. You can get one for $30 to $90 dollars. The green lasers are around $200 or more.

Post by: ICEMAN on July 14, 2009, 08:49:34 PM: Dave Stiles....my elcheapo red "stick in the end of the barrel" laser puts out a neat tiny dot at 100 yards, you just have a hard time discerning it in bright light, once you locate it, it is easy to see, just hard to find it is so small... It is not spreading out as suggested. I have yet to see any laser sight, laser bore sighter, laser pen pointer or construction laser do that.... :dunno:

Post by: bearpaw on July 15, 2009, 09:44:14 PM: I have never started out shooting at 100yds, I always shoot at 50 first. :dunno:

If you guys have bolt actions, pull your bolt, set your rifle up solidly pointing toward the target. Look down the bore and center the target. Then raise up without bumping your gun and look through the scope, then adjust as needed and repeat until it appears deadon. Almost everytime I have been within 5 inches or less with the first shot by doing this.

I have a whole slew of laser cartidges that I should put in the classified.

Post by: Jekemi on July 16, 2009, 07:28:35 AM: ICEMAN. That's great. My cheapie (.270 caliber shell that fits in the barrel after removing the bolt) spreads out a bit. I also have a few cheap, non balistic lasers that I picked up at various trade shows. I can shine them across the backyard to the neighbor's house, which is about 30 yards away and it is about the size of a nickel but pretty dim.
One of the freebee lasers will just fit in my barrel, almost the exact size as the .270 brass shell variety. It has a little ring on the back, which makes it easy to pull out of the barrel. I think they are a great way to get close. Follow up with a couple of shots to check accuracy and you are ready to go.
