Bore Sight

[aimtrue]

I have a red dot sight mounted on my Ruger PC carbine and want to zero it in

What type of bore sight should I use, a cartridge or muzzle load?

Would appreciate brand and model suggestions

Thank you.

I'll assume you are mounting a scope?

how about;
1) put scope in center of both adjustments
2) use a Large target at 25 yards
3) adjust to match your ballistics and desired range of use

Unless you are in the business of mounting and boresighting scopes, it's a waste of money to invest in one. Even after boresighting, you still need to do the fine tuning of the zero at the range.

I got a cartridge type from a local gun store-don't know the brand. I just chamber it and then adjust the dots so they overlap. I usually sight at 25m. So you will still need to go to the range with a rest and target to finish sighting in. I saved more than I paid in ammo.

I've a Barska traditional bore sight but don't use it any more except when I don't have a laser.

I think the one I have is from Laserlyte. It has an arbor that fits into the end of the barrel. It's worked well for several years. It isn't a substitute for final zeroing at the range, but it gets you darn close, and once you are on paper it's pretty easy to zero most optics.

I say most, because I'd bet just about everyone of us has had one setup that just didn't play fair.

just curious....what range do you plan to "shooting" zero and maximun range (with out hold over)?

I thank each of you for your responses.

After much consideration, I chose a modestly priced Sightmark Universal Bore Sight SM39014.

If the red dot is about 1 1/2" above the bore, a 15 yard zero should give you about the best "point blank" (+/- 2") out to 85 yard

Thank you Hunter.

I bought cheap laser cartridges off Ebay for 9mm and .223. They were less than $10 each.
I drew a plus sign (+) on the cartridge. They are not perfectly symmetrical, so I first zero the laser to the red dot at 50'.
Then I rotate the cartridge 90 degrees and re-zero. The same is done for all 4 points of the + sign making minor adjustments as needed. At 50' the lasers are off by as much as 1/4" between each point on the +.
That gets me close enough so final adjustments at the range at 50' and 50 yards is quick and easy.

I have an inexpensive bushnell muzzle bore sighter. It has collars for various calibers and gets me on paper every time. I also have a couple of the cartridge brass ones, but in all honesty, the muzzle one does its job. Even on iron sighted lever actions.

I purchased a SightMark Universal Bore Sight and zeroed my Vortex Crossfire Red Dot at 25 yards.

Then shot 153 rounds S&B 124gr FMJ onto same target.

I set up a target at 15 yards. From a rest, I fire one shot at a red dot that I have placed in the center of the target. Then, while looking through the sight, I adjust the windage and elevation until the bullet hole I created with that first shot moves into position over the red dot. From there, a few tweeks can get your point of impact where you want it. Since the 9mm is not exactly a flat shooting round, I will then move the target out to 25 yards, then 50 yards, and finally 75 yards and determine how much Kentucky Windage I may have to use at each range.
