I have a 7mm RUM in a sendero. I have not started reloading for it yet, but the guy I bought it from gave me three boxes of factory carts. I have been to shoot it twice the best group I have got so far is about 4". This gun should shoot better that this even with the remington ammo. Could the scope have something loose in it or anything?
Senderos normally shoot extremely well. Check all the normal variables such as screws that need lock tight on the rings. Mine shoots 1 inch groups at 200yds. The gun can probably do better if I were a better shooter. I sometimes get a 3/8 group at 100. It may be possible to get a lemon. Good Luck

I shot it agin today, 1st group was about 3", with two shots touching. 2nd moved over about 2 and half inches on two shots and 1 strayed back over. I have checked all screws on scope and gun. I am starting to think the scope may bad. It is Varix 3 4.5 x 14x50. Thaks for the help.
The Sendero's I have plus others that I have worked with really shoot. Since you have checked all screws, I wold swap Scopes next. If that doesn't work, take it to a Smith to check for damaged Crown, etc.

Sounds like something is moving on you. I use a VXIII 4.5x14 50 also. Mine is glass bedded with a 2.5 lb trigger. A lot of guys here could figure out the problem if they were with you. About the clean barrel post. If you start with a very clean barrel the first shot will be slower and possibly the second shot. Once you get a little fouling in the barrel the pressure and bullet speed increase. What groups do you get after fouling? Good luck.

The groups in my last post had 4 shots through it, before I shot it Friday. When I got the gun I cleaned it then went and shot it about 20 times. That day no two shot were close. It has a 2.5lbs trigger. Could the scope be bad? Thanks
D99, I have done all of that. I am thinking of takeing the scope off and cleaning the rings. I have heard that if you wipe your scope down with oil, like the gun, oil will puddle between the rings and the scope. Makeing the scope float.
Are you using a bi-pod? If so they are not condusive to good accuracy, they fowl with barrel harmonics. Fine for hunting bad for making small holes in paper.
Glass bedding your rifle is always good advice. A kit from Brownells of acraglass gel is $20. More than likely it's the best $20 you will spend.
The only non-glass bedded rifles I own are Blasers.

Please!!! Stay away from that foot pounds idea. Get your stock screws tensioned to 65 INCH-POUNDS. NOT foot pounds. Start from there and don't change anything else. Change only one thing at a time. Try different ammo after all screws are tight and the barrel cleaned. Go from there but one step at a time. Maybe to test the scope, use a large target at 100 yards. Shoot to the upper left corner. Click the adjustment two inches to the right, shoot. Then down two and shoot, left two, shoot, then up two inche, shoot again. If it doesn't bring you back to the original group you may have a scope problem. The Leupold should be guaranteed so call them and tell them your story all the way through. They will more than likely help. I have never had a bad Leupold but a Redfield went sour with moisture once and Redfield fixed it for free. Good luck.

Switchback, I would look to my scope after what you have described. If you have access to a bore sighter, it can help show if a scope is defective. Mount your boresighter and take note of where on the grid your crosshairs reside. Make some significant adjustments, say 10 clicks in windage one way or the other and 10 in elevation as well. Firstly if your crosshairs don't move on the grid than get rid of the scope! Secondly, reverse the adjustments you just made and see if that gets you back home (to the location on the grid you started at) if it does that's a good sign, but your scope could still be toast--you need to mount a scope of known precision--(one you knows be's working right) and shoot your rifle with it. That will let you know if it's the scope, or something else in your system--could be crappy rifle (doubt that) or probelms in mounting system.
Good Luck--Don

Remington only makes the one load for it. What do you mean about the scope being bottomed out? I have not heard of that. I have shot off a lead sled twice and bags once, no differnce, it still shot everywhere. I am going to try the bore sighter thing this week.Pack, I don't think the gun shoots well enough to try that. Thanks for all your help.

Switchback, Not to rain on your parade but it might not be the equipment, have someone else shoot it before you overhaul everything.

Switchback, you really need to quit "talking" about that scope and put another one on there. Even if it's just a loaner to troubleshoot with. Then after that you can purchace one or sent yours to the factory for chekin' out if the scope proves to be the problem. And that sure sounds reasonable.
Also, stepchild has merit here, have the guy you bought it from, or someone at the range that seems competant shoot a group through your, That could be very revealing.

Originally posted by gixxer: the sendero comes with the HS precision stock, right? If that is the case it has the aluminum chassis, can you still glass bed?
Yes, you can glass them and mine is and shoots near perfect. I got a .360 group Sunday.

I have let two other guys shot it, samething. I thought the first time it was me, but when two other people shot it I knew it was the equipment. I sent the scope back Monday so I should have end of next week. Thanks Eric
Glad to here it wasn't a shooter problem Eric. I've been wondering how it was going. Remember while the scope is off, to check the base for loose screws.
Let us know how it's going.

I had a problem with one scope and it was because it was bottomed out. I let someone else mount it, and although it held zero for a while it did break. When I got it back and boresighted it myself I found I needed .017" shims in the front.
Hope you centered the scope and made it as close to zero as possible without using the scope adjustments. If you didn't you may want to pull the scope and make note of where it is adjusted to, then center it. Lap your rings and use shims to get it as close as possible. This should help it last much longer.
