Rifle HElP!!

Help! Help Help!!

Here is what I have.

Browning A-bolt with Boss system
Leupold Vx-lll 3x9x50
Shooting Win. 150gr. Silver tips.

I have been using those for years with no problems till now. First it started of with several misses this year and come to find out the boss system was loose. Got it tighten back up where it was and then 4 kills in a row by 2 different hunters. The next hunt another miss. Put gun in a weighted vise got it where I wanted it all group touching rack other 2 inches high. I'm good. Next hunt fired and a gut shot. Thought it might have been me. Yesterday really good buck steps out. Fired and a miss at 220 yards. This morning. Doe steps out fired. She hits the ground at 168 yards. But the catch is. It was not where I was aiming. Hit her in the back bone right in front the hind quarter. Get to the camp I shot 3 times. First was 4 inches high 3 inches to the left. Second shot was 2 inches high 3 inches left. 3rd shot was dead line with bullseye 3 inches left.

Could this be a bullet problem are what. Don't know where to start. But I gotta get a fix fast. Prime time is coming up on us.

Capt. Eric

I would lean to the boss system causing your problem more than the bullets. I know several people who had the boss system, amd it gave them nothing but trouble as far as grouping. You have a fine gun, nice scope, and good bullets. Those bullets were actually designed for competition shooting. The only other thing I would check, is make sure everything is tight on your scope (scope,mounts, etc). Good luck and let us know what you figure out!!

A BOLT

I THOUGHT I WAS THE ONLY ONE HAVING THIS PROBLEM. I WAS BEGINNING TO THINK IT WAS ME. I HAVE AN ABOLT WITH BOSS 300 WM AND SHOOT 165 GRAIN BULLET. I HAVE A NIKON 3X9X50. I MISSED A NICE BUCK LAST WEEK AT ABOUT 200 YDS. ABOUT AN HOUR LATER I SHOT A NICE DOE AT THE SAME DISTANCE AND HIT HER HIGH AND TO THE LEFT. I TOOK MY GUN TO THE RANGE AND SHOT A COUPLE TIMES AND WAS RIGHT ON. ATHE BUCK I TOOK MY TIME AND WAS NOT SHAKING BUT MISSED A BROAD SIDE SHOT, STRANGE. I WAS TOLD ONCE THAT THE TEMPERATURE WOULD MAKE A DIFFERENCE ON THE BOSS SYSTEM.

All year

This has been going on all year and I tired of it. I had this gun for 10 years and shooting same bullets and never had a problem till now. I don't know what to do. It will be retired after this year. If you figure it out please let me know. I'll do the same.

calibration

you said you had to tighten the Boss. If so you may want to check the calibration for your caliber and for the so-called sweet spot.You can find that information in your manuel or the browning website. If that doesnt seem to be the problem check for fooling in the barrel.fooling will effect accuracy.Hope you can get it right before the Big one steps out.

BOSS is the boss!

Not sure if this matters, but what caliber is your rifle? I have 2 A-Bolts 30.06 and 300 Win Mag both with the BOSS system. I cannot ask for any better from these 2 rifles. I have been shooting them both for years with no problems, and with 1 inch or less groups. Like Bucks only said, I would check to make sure everything is tight on the scope mount. Just a tip, I run a bore snake with Hoppes #9 through my rifle after every 2 shots on the range and then give it a through cleaning with some foaming bore cleaner at the end of the day anytime I shoot. I also check to make sure the BOSS is tight after every shot. Also, are you shooting the BOSS with the ports or the solid sleeve? I have noticed that my 2 rifles do not shoot the same if I shoot them with one then switch to the other. Hope this helps.

30-06

I shoot 30-06. I love this gun. This is the first issue I have had. Today I took the boss off and cleaned everything took scope off and remounted it and got everything tighten down. Now I do notice this. When I look throw my scope and I move my head up and down my crosshairs move up and down. Kinda strange. It's like I need a anchor point like bow hunting. I don't think that suppost to happen. I'm lost and need this fixed!!

Capt Eric

Dont get paranoid. What you are talking about with your cross hairs moving is normal. It happens with every scope. How did your gun shoot today after tightening averything?

Have the bedding checked

A friend was having similar problems. He zeroed before the season had two misses. Checked the zero, it was off. Resighted, and missed another deer. Changed scope and mounts. Same results. Brought it to a very competant gunsmith he dissassembled, diagnosed the problem and rebedded the action. Groups shrunk 1/2' and still going strong. Just another thing to think about.

Break down

Ok, I just completely broke it down, from the scope, mounts, barrel and stock. It did seam like there was a few bolts loose so I will go shoot today and see what happens. Everything is tighten down now for sure. Double and triple checked all bolts

Crosshairs

Your crosshairs shouldn't move like you said they do. That's called parallax. Just like you said, if your eye is not in perfect alignment every time, it will affect your point of impact.

Scope

I had the same problem with my A-Bolt 300 short mag. It was the scope. This is the most accurate gun I have used.

SOLUTION

I SUSPECT YOUR SCOPE MOUNT AS WELL AS THE BOLTS ON THE RINGS ARE LOSE. RECOMMEND YOU TAKE YOUR GUN TO A GUNSMITH. TELL HIM TO REINSTALL THE MOUNT & SCOPE USING LOCK-TITE (DEMAND LOCK-TITE). THIS SHOULD SOLVE YOUR PROBLEM.

no loc tite

don't lock tite your scope, just tighten it down, if you lock tite it, you can damage it down the line if you need to change/re adjust it.

Loc Tite

I have seen this happen to a friend's rifle and the cuprit was a sheered off base screw. Drove him nuts for awhile. Loc Tite every screw with blue loc tite, and buy a fat wrench and put the recommended torque on every screw. The recommended torque is different for base, windage, and ring screws. The fat wrench will allow you to have every screw tightened to the recommended torque. Red loc tite is not serviceable. Blue loc tite is, meaning the screw can be taken out down the road if needed. I mount all my scopes myself because I got tired of gun counter people mounting scopes with no loc tite and no torque wrench. They will come loose if not installed with loc tite. It's just a matter of when. It is a joke to see those people mount a scope. Do it this way and you will not touch the scope for a long time.

Gun

Well after a gun break down I went and resighted in and got it where I wanted and I was fixing to leave. I took one more shot and bam 7 inches low. We I wiggled the scope an the entire scope moved. I didn't take off the base mounts when I broke it down. So now I think that was my problem. I came home a broke it all down again completely and Blue loctite base mounts and scope mounts ang going resight again tomorrow. I loctite it with the blue before I read the threads so I'm at a plus. This should do the trick. I will update tomorrow. Thanks for all the help!!

Darn

Wish I had seen and commented on this earlier. I had problems a couple of years ago and it cost me two nice bucks. Loose mounts was the problem.

Another tip for everyone that might save you some pain like I had that year. Don't rely on one shot to verify your rifle is 'on' when you check it mid-season after a miss.

Loose mounts. The more your shoot the more erratic the group gets.

A-BOLT TROUBLE

Before you do anything else check your action for tightness. If you can get your hands on a inch pound torque wrench. A good start is 45inch pounds for the factory stock. This could be your trouble.

BOSS has been a problem

I know there are many rifles that have the BOSS system that performs flawlessly, but I had the same problem with my Winchester Model 70 30-06. It was never consistant for a long period of time and brought to the gunsmith twice, all to no avail. I finally had the BOSS cut off and the barrel re-crowned, and the rifle has never been off. I know for a fact that many people have had great success with the muzzle brake, but in my particular experience, having it removed made all the difference. Good luck and happy hunting.

Browning

Eric, If you want to shoot long range 'dump the Boss system' I found them to be unreliable years ago, Get a Remington model 700 The most accurate rifle out of the box going.

Even better their Auto model would be lucky to hit a pie plate at 100 yards 'Trash'

Good luck with your problem

Target

Eric

Target

Gun

Ok just got back from the range!!!

Here is what I done and the gun did need some over looking.

I gave the gun a total breakdown and tighten every bolt I could fine. I shot it yesterday and it grouped fine and I was fixing to leave and I told myself. One more shot. Well I'm glad I did. It shot 4 inch left and 6 inches low. Well my base mounts came loose. Came home broke scope down and reinstalled it like it was new with loctite and got the parallex adjusted right and I changed bullets and got the boss system set to the hornady SST. Now it is doing its thing.

Picture below

Bottom 3 was first grouping after I got it set and top was the last grouping at 2 inches high. I also shot a box and a half to recoat my barrel with new bullets. Now I hope I got this. It's also nice to see the grouping almost touching each other.

Thank all of you for all the help and I hope it help some others.

Browning BOSS

I have an A-bolt with the BOSS in 7mm Mag with the composite stock. I don't want to brag but I have not had any problems with mine once set, except for a few times with operator error. At the range mine is a tac driver as long as you don't pinch down on the front of the front of the stock where you have the needed clearance with the floating barrel. One time I was shooting it at the range just to check for zero and I had a vise type bench rest that clamped down the front of the gun. It shot all over the place. I find even if you grip the gun to hard in the front it will throw it off. I have learned just let my hand rest a little farther back when shooting. The only thing I dislike about my gun is that I am always bumping the tip of the barrel getting in and out of the stand, and that always makes me wonder if it will throw me off the next time I shoot.

Loose mounts

Use the blue or green loctite-never RED! Problems occur when threads are pulled(over torqued). Use the correct loctite tighten as required and your problems will be solved! Inspect the bolts! If the threads look damaged-replace them0or they won't ever hold their torque value-hope this helps!

abolt

here it is. I've had the same problem and have done a lot of reserch on this. My problem is that i have been resting my gun on my shoot house. This is a no-no as the barrel is supported in a glass bed and moves a little when the gun is shot. It is supposed to do this. when you rest it on the house of stand you prevent the barrel from moving correctly or differently from when you shoot on the range. i have a a bolt with boss in 300 wm. to me the best gun i have ever owned. the only problem i have now sence I've learned to stop resting on the shoot house is i keep hitting the top of the barrel on everything sence the boss adds about 5 inches to the gun.

Silver tips

I had the same problem. I shoot a browning 7mm white gold medallion w/o the boss. Exact same thing was happening 150 grain ballistic silver tips. What was happening was the coating on the bullets was coming off and coating the enter barrel. Run a brush and and a swab through your barrel every 5 shots
