7mm Sight in help

[Duckslayer89]

Have my dads interarms 7mm I mounted a new scope on with brand new base and rings from leupold. Brand new 3-9 vx2. For some reason I will shoot 2 good shots and then it throws a bullet 10 inches to the left or right. Then it will shot a good shot. Then throw another bullet next to the one it through earlier. I took it home tonight and scrubbed the barrel with copper fouling foam and wiped it. Got a surprisingly large amount of crud out but I don't see how this would make it throw bullets THAT far at 100 yards. Could the barrel be worn out?

more info. Wood stock? same ammo? how many times have you had the third shot go sideways? does it always repeat the 3rd and 5th shot go sideways? What kind of rest? factory ammo?

First thing I would check is your bases and rings. 10 inches left or right sounds like a scope issue. Not likely the scope is bad since it's brand new.

It's a wood stock gun, same exact ammo Remington core lokts 175. I haven't noticed if it repeats this every 3rd or 5th shot. I'm going back tomorrow morning to the range and I'm going to sit there and let the barrel completely cool to the touch and see what happens after the scrubbing I did and everything. If it won't shoot I'm taking the scope off and putting it away getting frustrated!!

I used a torque wrench and loc tite on everything, scope bases and rings very tight but I thought the same thing

I'll be at Tacoma Sportsmans club at the members range in the AM. I'm using just my gun vise as a rest not putting any torque on the gun or clamping the gun just resting the front of the stock on it nice and easy super solid though

Also it's only moving side to side not up or down

in my experience a shot moving just laterally is the pressure put on the trigger not pulling it straight back---but i can't see it moving POI 10 inches with just trigger pull....even though the scope is new it may still be defective.  i've never had core lockts shoot clover leafs but that group is rediculous

Sometimes having another shooter shoot several groups to see how consistent this issue is..

It's not even a group it's like a shotgun blast. First three grouped like 3 inches. I'm wondering if it's just really heat sensitive. If I can't figure it out tomorrow I'm probably done buying ammo for it trying to figure it out

How did it shoot in the past, prior to putting the new scope on it?

that is really weird grouping. with a huge variation like that I really have no idea.

Two things I would try, first have a friend or someone else shoot a couple groups as Mountainman said.
And two pickup another brick of different ammo. The only time I have seen radical flyers like this (eliminating the human part) is rings/base not secure. If the gun does not like the ammo, it can cause some good inconsistencies. I have never seen 10 inches of difference in 100 yards caused by ammo though. I have seen flyers like this caused by the shooter anticipating the shot.

My ruger 7mm did the same thing.(still does a little). I would shoot 2 shots decent and 1 flyer. I bedded the action and made sure the barrel was not contacting the stock and just about everything I could google I've tried,except reloading. I'm shooting the same grain bullets. My groups tightened up quite a bit but still have the flyer. My special ops buddy said it was the style of barrel. Once it warms up I guess the barrel whips more? It's a pencil style barrel I guess. My first 2 shots touch at 200 yards but that 3rd one is enough to make you scratch your head.

Have you tried tuning it with a Boss/brake?

It shot good when we first got it, then shot like crap. So I was at the range trying to figure it out and noticed the scope looked sideways a little and I noticed the windage screws that hold the back ring tight were loose! So that's why I bought all new base and rings and loctite Everything. Sent the old scope into leupold and they sent me a brand new one. I was stoked to get it shooting for my dad and now it's still giving me issues. I'm honestly wondering if the barrel was just to warm the 7mm gets hot super fast. But would a warm barrel throw shots 8-10 inches?

Man I was really scratching my head today like WTF. Definetly not anticipating the shot it hardly kicks compared to my 338. The gun has a great trigger though. I really wanted to get it all squared away for my dad because he's always using my guns to hunt with and wanted this one to be his
