How to use a Rifle Boresighter

[Nickt]

I have desided to buy a boresigher as my attempt to zero my .223 has cost me dearly on bullets and range fees with no result!! The question is, do i use the sighter with the mod on or of? I intended to only shoot it modified.

 

Many thanks

 

PS. Any recomendations on a good but resonably priced boresighters?

you shouldn't really have any problems if you take the straight forward approach of taking the bolt out, with the rifle on the bipod look through the bore at something 100 plus yards away then move the scope onto that point. Then try on a target at 50 yards adjust the scope further and then take another shot and adjust if needed. It really shouldn't take you more than 3-4 bullets unless there is something amiss

As above, look down the bore with the bolt out (obviously) with the rifle ideally fully rested and in a position where you don't need to hold it whilst on a point of aim. On a bipod ideally with something like a rucksack or rolled up jacket under the butt so it will just sit there. All you then need to do is making sure the bore is on your point of aim, adjust you scope to come onto the same point of aim. Depending on range to your chosen point you may wish to set the sight high or low due to trajectory.

 

With a .223 specifically, if you're looking for a useful zero of an inch high at 100yds then I'd suggest boresighting at 50 yds, firing at 50 yds to confirm then moving to 100 yds for your final adjustment and confirmation.

Edit: this is based on the trajectory, the first zero point will be roughly 50 yds.

Thanks guys. That is what I did before I went to the range, looked down the barrel and aligned the scope. So you can imagine my surprise when at 100 yards it didn't even hit the board!! I have put it down to a faulty/unsuitable scope, but nevertheless the experience was not a good one. By the way the scope that came with it was a Center Point 6-24x50. I have never heard of them myself, and after some investigation they seem to have been imported for air fifle use. It has gone back now.

get the board a lot closer

First off find roughly the centre of adjustment, then put scope on something cheap to shoot, give it a good workout to check turrets track and return correctly

also use this opportunity to see if mounts are accurate for height and windage{ just had serious issues with this, and nearly scrapped scope. turned out one mount was slightly lower than the other!!. switched them and perfect}

I put rifle in a workmate and boresight on a pylon top at about 1200 yds,, only usually needs minor adjustment after that
