I have a .375hh in rem798. when i first mounted the scope, it shoots so far to the left i cannot get it on paper at 25 yards. its a foot left at 25 feet. looking at the rifle, the scope does not line up with the bore. i have lapped the hell out of the rings, it helped a little, but still off. can i use any bases that will fit a large ring mauser? or do i need to look specifically for rem798 bases? i figured the first thing to do is replace the rings and bases with new ones. the mounting holes seem to be drilled correctly. any suggestions on rings/mounts? also, i used a 2 piece weaver style mount and leupold qr rings. thank you. | ||

The 798 would use the FN rings. I would look to something like a normal Leupold and simply use the rear screws to handle the major portion of the adjustment. Just curious did you try turning your rear base and or ring around? As usual just my $.02 Paul K | |||

A foot left at 25ft = three feet left at 25 yards = 12 feet left at 100 yards! Your scope/rifle are 150 MOA out of wack!!!!!!! (assuming the scope and mounts are not defective)I really don't think you are going to be able to adjust anything to make this this thing shoot straight. I would look for a barrel/receiver joint that is mis-machined. Jason "You're not hard-core, unless you live hard-core." _______________________ Hunting in Africa is an adventure.

According to my further calculations: you would need to move the rear ring about a quarter of an inch to make it shoot straight.

yeah man its pretty crazy off. but i did take the scope, still in my qr rings, and set it on another rifle, and it was off.. so, either my scope is warped (joking) or its my rings. i'm going to go with rings. so i'll get some new stuff ordered. i think i'll try the leupold bases/rings this time. for a follow up question. i just got a smoking deal on a rem700 .338RUM. i'm going on a couple hunting trips so i'll get it when i'm back home first of december. i would imagine this rifle to have some fair recoil. i plan on putting a minox za5 3-15x42mm scope on it. as long as i get decent bases/rings, do i have any issues to worry about? or are there specific ones any of you recommend against the big kickers? thank you for your help. | |||

ramrod i turned the front base around, no change. after i set the scope, still in the rings, on another rifle with weaver style bases, and it was still off, i think its the rings. i know this rifle handles a scope and shoots very well, so hopefully its the rings that are the culprit. | |||

Are the base mounting holes in the receiver in line with the bore? "Peace is that brief glorious moment in history when everybody stands around reloading". | |||

Check how the ring fits the base. You are mix matching manufacturers and there may be an issue with the way they are sitting on the bases. Also what kind (brand) scope are you using? Two: you "lapped the Hell you of the rings" Do the rings still hold the scope? maybe the scope is shifting with each shot. Are they the correct bases for the rifle?? Do you have to force anything to get the rings on the bases? www.KLStottlemyer.com Deport the Homeless and Give the Illegals citizenship. AT LEAST THE ILLEGALS WILL WORK | |||

kcstott, the rings still hold the scope firmly, even after lapping. after lapping, when i place my scope ring alignment bars in there, they line up almost perfectly. from what i can see the rings fit on the bases correctly, they are snug and no gaps or anything anywhere. they are rock solid once tightened down, and i do not have to force anything. the scope is visibly off-line with the bore. you can see it just by looking down at the rifle. they are the correct bases, at least the package says so. i'm packing for a 3 week trip, i'll order a new set of rings/bases and install when i get back. this is a play around with rifle until i can get enough money to go hunt something big, so its not like this is life or death. i just hate it when stuff doesnt' work correctly (or when i'm doing something wrong, hate that too). thank you for your help, i'll report back in a few weeks when i get the new hardware on. and the scope is a minox za3 3-9x40 | |||

That is a very good question. In my experience the answer is likely no. Even when apparently inline, they tilt every which way. Just stick four screws in and look at them leaning fore and aft, left and right. This is one of those rare occassions when changing the screw size to 8-40 is justified IMO.

Great points. Another way to check barrel/receiver/scope mount hole alignment is to place a screw in the front ring and one in the rear bridge, then set a yardstick against the screws with the end of the yardstick out near the muzzle. If things are misaligned the yardstick/barrel will diverge and it will be easy to see at the muzzle.

Time to start measuring things. 1. like z1r said, put some screw in the holes w/out the bases and see if they are straight. 2. Look down the barrel with the screws in place and see if they are off center. 3. Look to see if the holes on the bases are on center. 4. Same with the rings, Check to see if one side of the ring is significantly thicker then the other. Although I seriously doubt that would be the case I've been surprised before. I'd bet it's either the bases are drilled of center or the receiver is off center. That action is one of Remington's Import actions so it would not surprise me. Not saying their stuff is junk just saying it may have slipped by QC on the way out the door. www.KLStottlemyer.com Deport the Homeless and Give the Illegals citizenship.

I have a Charles Daly, same manufacturer as a Rem 798. I did not check to see, other than visually, if the receiver was drilled right when I could not get on paper so I just got a set of windage adjustable rings. Don't remember which way it was off though. QC at Zastava leaves something to be desired. Rad NRA Benefactor Member | |||
