I have a 50 mm objective Kahles mounted in Leupold rings on a 30-06 I am working with. The scope cannot be moved anymore to the rear as the front ring runs into the beginning of the objective bell. Taking the scope off today I noticed that the bottom Leupold ring had deeply scored the aluminum tube at the back of the bottom ring. I had taken it off as I am trying to figure out why the gun will shoot a 3/4 inch 5 shot group and then either vertically string or today as I had doctored the barrel support staunchens with 3 thicknesses of electrical tape to releave foreend pressure it just started to throw the 6th and remaining shots from a warm barrel just all over the map. I removed the tape as verticle stringing is better than owning a shotgun rifle! You can see daylight through the space between the barrel and the widest part of the objective, but I have never looked at it hot. If it is touching the barrel would this result in weird shooting? Then I don't know why the front ring would be scoring the tube of the scope at the bottom and if this may be causing a problem. Right now I am ready to send this rifle on down the road, but it is just so accurate when it is cold...it is just a PITA to develop loads with. A gunsmith told me it probably has some stress in the barrel and when it heats the barrel warps and it will not shoot anymore. I moved the scope 1/2 inch forward and will try again. Any thoughts? | ||

Hello Jimmy. You need to get taller mounts and or rings. You are going to wreck if not already done so, a very expensive scope. It sounds like you have binding somewhere. I would get some medium Burris rings with the teflon inserts (signature rings) and get that scope around 1/8 inch above the action/barrel. Pictures would help. Regards, Rick. John Deer tractors and Sako rifles....just doesn't get much better. | |||

Anything that touches the bbl. can change the harmonics. I vote taller rings. LIFE IS NOT A SPECTATOR'S SPORT! | |||

Take your rifle to a competant gunsmith and let him bed & fit it. You can't rely on electrical tape to solve your problem as your barrel heats the tape changes & slides. What brand of 06 and model ?You need to get extended higher rings or a new scope.A sportswriter here in CA just went on a rant about 50 mm scope bells not being needed he said stick with the 40mm then all fits.I have Sako Rifles in 06 & 300wm that were bedded & tuned by a master gunsmith then 3x9x40 Leupold Vari X2 scopes with CPC reticles were installed.I've used the 300wm for Mule Deer,Bison & Elk and the 06 for Mule & Blacktailed Deer ,btw they're very accurate. | |||

I am beginning to see the problem with 50mm bells! I am going to put a Zeiss scope on the gun from another rifle and see if it has the same problem first. It is tough to sight the rifle in, but the first few rounds shoot well. The gun has always been a puzzle that I have tried to ignore as it shoots well at first and then does not! I do not want to blame it on the rifle just yet but the scope may have to go back to the factory... Weatherby MarkV synthetic stock. | |||

Just another reason to hate a 50mm or larger bell. I don't like a high mounted scope, and as well the big bells bang into everything when carried as they are wider than the forend. I don't want anything larger than 42-44 mm objectives on anything that has to be carried. As well if the first five shoot 3/4 in. it wouldn't worry me any, I'd just let the barrel cool and shoot another rifle in the meantime. That said, it could be the barrel anyway, if they were straightened at the factory, it will leave stress in it and the barrel willl try to go back as it heats up. This is what your gunsmith is talking about. I have a Sako that is this way in 7Mag. If you sight it in and get the barrel hot, come back next week, the cold barrel group will be 1.5 inches lower than before evey time. It doesn't hurt a hunting rifle as I figured this out twenty years ago, I just let it cool down when sighting in and it will never get that hot hunting. A varmint rifle would be another story. If there is .100 clearance between the barrel and the scope bell, it isn't going to touch no matter how hot it gets IMO. A shot not taken is always a miss | |||

I've always been happy w/ 40mm & smallerobj, for a hunting rifle. I'ld rather have the weight in the rifle bbl. not the scope. LIFE IS NOT A SPECTATOR'S SPORT! | |||

here is another bit of info. Although you can pass a peice of paper between the bell and the barrel, there is also a spot below the bell where the blue on the barrel is worn off...I may just get rid of this scope anyway,,,,it is not broken by any means as the adustments are consistent and the gun when cold reliably shoots a 3/4 inch or better group every time,,, the 7mm mag story is the same as mine and I had settled in on 165 grain powerpoint bullets knowing after 3 years of owning the gun/scope that my first bullet was going where I wanted it to. Now I want to develop some loads and it is just one of those things what a pain...My 270 winchester in the same Mark v style does not have this problem. is more predictable and I understand that if it shoots bad it is either the load or my lack of focus...the 270 shoots 20 130 sierra's with RL22 and win mag primers into a very nice 2 inch or so group at 100 yards.....it will take a long time to develop loads with this 30-06 gun I really wanted to get it shooting with 180 grain NP's. I do not like the leupold rings on the gun either and if I change to a smaller belled scope I am going to get Talley rings and mounts, I wonder if people would think me crazy for wanting a 36 mm bell! Finally would you sell this gun?? | |||

ditto- I went through the huge glass phase. last year I took an offhand shot at a deer with a borrowed rifle that I doubt I could have made with anything else but the 7x on it. | |||

I have shot a number of deer at about 350 yards paced using 3X9 and 2X7 scopes set on the lowest power. I don't feel the high magnification or big objectives are worth the trouble to carry around on a rifle used primarily for something as large as a whitetail. | |||

Hey Jimmy, Unless there is something wrong with it, that might be a mistake. Where I've Hunted for many years, the Hunting hours are from 1-hour before legal sunrise until 1-hour after legal sunset. The Large Objective Scopes allow me to see Deer clearly when smaller scopes can't compete with their light gathering ability. And if your Hunting hours are 30-minutes shorter on each end of the day, there are still plenty of heavy-overcast days that the Large Objective will give you an additional 12-20min of "Prime Time" Hunting(on each end of the day), when it is totally impossible with the smaller Objective scopes. If a person lays in until the sun is up before going afield, doesn't Hunt during inclimate weather and comes in before sundown, then the weenie scopes will do them just fine. Or if all a person plans to do is put holes in paper, they also work well. The only real advantage the weenie scopes have over the Large Objective scopes is they weigh a bit less. Easy enough to see how much by simply looking in the manufacturers catalogs. So, if "weight" is more important to you than actually Hunting during "Prime Time", then going to a weenie scope would save a few ounces. Good hunting and clean 1-shot kills. | |||
