If that doesnt work call Browning ASAP. It could be a warranty issue.

This sort of thing can be just loose scope mounting screws. Have seen it a few times. If you have a cheap, no-name scope, the scope itself could be the problem.


Also check bedding screws, if the barreled action is moving around in the stock, it won't shoot consistently.



Consider the shape of the groups - are they more or less round, or are they vertical or horizontal, mostly?

Doesn't matter any longer- I gave up the Tikka. That little piggy is going to market. It was a little too heavy for my tastes.

I did get it to group with a Leaupold, and I'm sure it was the Weaver- I mounted it with a DNZ one piece scope mount, lapped the rings, torqued to spec. A local guy that knows checked the bedding mounts- they spec'd fine. He recommended two additional beds near the rear lug and the front of the stock to reinforce it all- but that's just more $$ spent going through a trail by error to make it work.

The Tikka was long in the throat too.. so I prob. hadn't found the happy load that would work best.

All in all I figured I could throw more $$ at it, or just buy a Browning. I like the 6.5lb weight of the Browning- makes for a nice carry package chasin mulies around.

You know, I have never owned a Tikka, but, from what I read, they are usually good shooters.



Rounds like the 7mm Rem Mag sometimes will shoot say 1.5 inch at 100 but will be under 2 inches at 200. Or so I have read. The idea being that the big long bullet at high velocity does not completely stabilize in the first 100 yards.


Regarding that last, it is my experience that 1" at 100 does not necessarily mean 2" at 200. Sometimes better but usually worse.



That said, from what you posted, that Browning shoots damn well, it's lighter, so go with it I guess.

The gunsmith I spoke to said the Tikka composite stocks are consistently very accurate, and a big part of that is the fact there is literally no deviation from stock to stock to stock. The tolerances are insanely tight. What he has seen is that a number of laminate stocks can have inconsistencies in them, and like a wood stock from Tikka or Saco they can often benefit from some work.

But yup this Browning is a shooter, and it’s definitely a better optioned rifle.

Sometimes you gotta adjust the stock to get the barrel more free floating. Barrel vibration has an impact to accuracy.
Take it apart, make sure it's properly bedded so that the barrel isn't touching the fore-end. The internet might show you a few tricks. In extreme cases you might have to replace the stock or modify it.

To my 51 year old eyes the Leupold was clearly better. The shop owner agreed. We tested them both outside, looking up an object on a hillside (no trees) about 200 and 300 yards away. The Burris was a much darker image, and the FPP reticle is darned near useless unless you are at 9x mag or higher. The Leupold was clear as a bell and the reticle clearly seen at 5:30pm- still ample light. Didn't matter the magnification.

I'd say scopes are one of those things that I really need to 'see' before I'll leap..
That's one thing keeping me from trying long-range shooting: I have no time for mediocre optics. Based on statements in second paragraph above, wondering if that Burris fails at two crucial times of day: dusk and dawn. That would be typical of non-premium optics.

My eyes will be 51 in two weeks, btw.

I have Zeiss binoculars bought 11 years ago that will be with me until the day I pass, they're real spiffy in dodgy light. Glass a Civil War battlefield with those and wonder what Gouverneur K. Warren was thinking as he observed enemy positions from the summit of Little Round Top on Day 2, e.g.!

I have a Zeiss short-range scope not sure what to do with quite yet, a 1.1x5 with illuminated dot: it's FAST for short range, dangerous game and will likely go on a 'Scout' rifle build, for sub-300 yard stuff, also likely at dawn when deer are active near treelines and weird shadowy light. Problem? Kinda spendy!

To buy something of similar power to that Burris, thinking one might wish to go NightForce 3.5-15x50 NXS Tactical Riflescope w/ Illuminated Reticle to do it right. For (cough) a bit under two grand.

Expensive sport, to do 'right' though if the Leupold does similar for half that, in what they call their 'mid range tactical scopes" line, hey: power to you.

Tried some more loads today. Moved bullet seating to .030 off the lands, 68grs H1000 with a 140grn GameKing produced .559” at 100yds.

Sticking with that for a hunting load.

My other loads and bullet seating trials resulted in .644” and .642” at 100yds. Seems whatever it gets fed it spits them out fairly well.

That ought to be good enough! Latest American Rifleman has an article on the X-Bolt, an interesting gun, from what I read they all tend to be tack drivers. Made by Miroku.



What the heck, enjoy!

Yup- Japanese, lol.

Last Sunday at 200yds - grouped .775” off sandbag rests.

I lightened the trigger when I got home. Gonna roll some 160gr GameKing rounds and see how heavier bullets do...

Like I posted earlier - 7mm Rem Mag frequently produces more impressive groups at 200 than at 100 yards.


Me, I would try some Nosler Partitions - they probably won't group as well as what you have tried so far, but they have a better terminal effect on game, and from a field position, if you can really shoot with more practical accuracy with a .5 MOA rifle than 1.5 - you are a damn site better shot than I am.
