Ok gents, here is the deal. This past deer season, here in south east Texas. My step dad and I were hunting. The ranges we were setup at was about 120 yards TOPS!!
I prodded and prodded for my dad to use my 1894 Marlin in .44 Mag, instead of his older .22 Hornet which is a tack driver to about 100 yards. I know, I know its WAY TOO SMALL. My dad is a bit stubborn. He was raised outside Kingsville and has taken a many a deer with that rifle. All have been neck shots. Well, this year he decides to take a text book perfect broad side shot on a small buck. He says buck may have been 130-140 lbs.(Typical east texas deer size).

He heard it bleat as it ran off. Needless to say, lost it!! No blood trail, NOTHING!!
Small bullets = Small Holes.
He felt so bad and was so dang mad, I could not rub it in about using my .44.
BIG BULLETS=BIG HOLES=LOTS O BLOOD

Anyway, he says, Ill never do it again, Ill never hunt deer with it again.
Then he wants to go look at rifles. He lives about 40 miles from Conroe so we head to Academy. (Me, Im all about simplicity and what works. Im a .30 caliber guy and my hunting rifle is my model 70 coyote in .308 Winch. I took my first deer with it last year).
So we are in Academy, and hes looking at all the .243s. Dont get me wrong, I like .243s, but he was really eyeballing the Remmy Model 770 with the Bushnell 3-9 scope.

I kept prodding him to get the friggin 336 marlin in either 30-30 or the .35 Remington. Nope, aint having it.

He walked out with it paying like 408 w/tax. We get home, bore sight it, and it looks to be a rather accurate rifle..

His first day hunting took his first buck in years. Aimed for the broad side shot in the heart at about 70 yards. Dropped the buck where it was at. When he walked up to take a look, he blew away about of the backstrap. Yeah, that far off to the left. My dad is a retired DPS trooper and a fine shot. He can pop feral cats with his 22 mag, or 22 hornet, all day long at 120-150 yards. He used to own a .243 but his ex wife sold it. He took a many a deer with it too.

I have one of those nifty laser bore sighters and have used it to great success with my .308, my wifes .308, and my .44. So I figured why not try it on his. Well we did, and it was way off from zero. We changed scopes, bore sighted, still way off zero. Were talking almost HOURS OF ANGLE, not minutes.

My dad and mom live on a fixed budget and I really hate to think that he bought a piece of you know what, but that is what it is looking like. We will head back to the range in a few weeks, but I want to get some of your opinions.

I easily print 1 inch groups at 100 with my model 70.
My wife consistently kicks my butt and gets about .75 to .25 with her Savage 16 in .308.
Both of these rifles were bore sighted with my laser bore sighter, so I do not think that that could be the problem.

And by bore sighted I mean, bored at 100 with laser on bullseye.
Then first shot is about 3-4 inches off at 100 yards. When I say it took me a total of 6 shots of Hornady 150 SST Light Mags to get it dead on zero for both .308s, I am not kidding. Man, I love that ammo!

Any help would be greatly appreciated!

Need more info. After you bore sighted did you go to the range and shoot paper? Are you saying it won't hold zero after sighting in at the range? Are the mounts properly tightened?

change scopes; i fired a guys, who could not zero, in about 3 rounds with 30.06. No it is not the best rifle, but they are comfy, nice recoil pad, and accurate , if kept under 5 shots, before the bbl heats up.

Oh , one more thing, I was just at the range this weekend, and a dude bought a bran new 7mag , boresighted, with a very nice scope, I think a Leupy, and he was all over the place. I gave him my tools, and told him to check his rings. yep , they were all loose. Academy sells good products, but they really don't have the guys or the range/distance to properly bore site.

Oh yeah, get a hi power magnifying glass, and check the muzzle, if it looks iffy, take it to a gunsmith or do it yourself. you would not believe how many out of the box rifles, have bad muzzles, and I mean from all diff types of rifle companies.

Here's how I would go about correcting this problem:

1. check all of the mounts and rings to ensure that they are tightened down and locktite (use the blue kind so that it can be removed later) the screws on the base and rings. Let dry overnight.
2. Bore sight.
3. Go to the range. Either start at 25 yards and move scope to the zero, or Put 4 targets touching each other and aim at the center of all four targets.
4. Use a good solid rest. Shoot a 3 shot group. Count the inches off of center and move the scope accordingly. Another way to do it is to try to hold the rifle steady on the bullseye and then move the windage and elevation to where the bullets impacted.

I would usually try several different loads or bullets to see what my tightest groups are before I settle on a particular round to use also.

Bore sights are no substitute for shooting at the range. From the way it sounds you are expecting way too much from a bore sight. The laser bore sights that I have say that they are designed to get you on paper at 100yards. Now once you truly have the rifle sighted in, you can re-insert your bore sight and mark exactly where it shows on the target in relation to the cross hairs. Keep that target available with the mark, and that will give you a very good (and accurate) reference point in the future to ensure the rifle is still zeroed and where it is supposed to be.

We have changed the scopes, they are still way off of bore, compared to POA.

We will go to the range and sight in at 25 and work our way out. I'll use the Loctite also. We'll then compare the BS to actual zero and see what the dealio is.


Thanks guys. I'll see my dad in a few weeks and we will give the other suggestions a try.

Really sounds like a scope and/or scope mount problem.

Could be the rifle though - maybe undue, or not enough, tension on the barrel from the hangar screw or something.

You're getting good suggestions from the others.


:cool:

you know, it sounds like maybe your scope mounts may not be square to the bore as well, which would be Remmy's fault...

Like Jeff F said, are you actually shooting the gun at paper to sight it in after boresighting? Boresighting is not a replacement for actually firing the rifle and sighting in, it is just to help you get on paper so that you can fine tune it. If you have properly sighted it in, I would check the rings to be sure they are tight.

Yes, the rifle is bore sighted and then shot at paper. It just drives me crazy how far off it is from the bore sight.

Skip the whole bore sighter thing.
Just sight it in on paper and adjust the scope as necessary.

If you can print decent groups on paper and you can adjust the scope to the correct POI then nothing else matters.

Bore sighting is just a tool toget you on paper to facilitate manually sighting the rifle in while shooting. If you can adjust the scope so the bullets are hitting where the crosshairs point, there is no problem, forget what the boresighter says.

If you cannnot get the bullets to hit where you are aiming, and you are running out of scope adjustment, you need adjustable mounts. If its an elevation problem, I suggest burris signiture rings with an offset kit, if its windage, you can go with the burris signiture, or a redfield style mount with a windage adjustable base, millet also makes windage adjustable rings for weaver bases.

Too many people think bore-sighing is a magical replacement for sighting a rifle in; it is not.

What he said.

243 is a fine deer round. The way my 788 kills whitetails is uncanny. Forget the whole bore sight hangup. If it's on paper, zero it and be done. If it wont hold zero after that, then that's another matter. If it wont shoot accurately, try different ammo.
