What's going on with my 270?

I went hunting this season with my Husqvarna 270 with a 6x Leupold scope on it after sighting it in this summer.

It shot like this at 100 metres:




I fell with the rifle on my back while bicycle hunting and fell pretty hard, hitting the muzzle on the ground and maybe the scope too.

I re-sighted it in in the field (I thought) and thought I was in the ball park but later I shot at a deer and after aiming for behind the front shoulder, actually hit it in a hindquarter. I took it to the range yesterday and while it seems to shoot a group in one spot, suddenly the next shot will be wild or it will shoot a group in another spot. Checked all the mounting screws in the base and rings, the action screws and the crown seems okay too.

I took long pauses between shots and let the barrel cool.

Did I rattle the guts of the scope to the point that it is doing this?

Send it to Okotoks?

The ten shots in the top part of the target below were with the scope at the same setting.

The other three shots are from another rifle.


 
You're right, should have tried with open sights for a few shots when we pulled the scope off.
 
Yep try irons or different scope first.
Did the wood stock pick up moisture from mud hole and is warping from ambient temperature changes from summer 'til now?

Any trash trapped between barrel and forearm? Fall hard enough to break any skim bedding of the receiver? Bent recoil lug?

Does the rear tang appear to be seated as before in the rear portion of the stock or has it ridden up off the stock?
 
Personally I would send the scope back to Korth with a letter of explanation asking to have it checked over from one end to the other. While it's away try the rifle with it's open sights or another scope. If the groups are still wild you know the rifle is the issue, and when your scope returns you will know it is good to go. I would then separate the barrelled action from the stock and look for anything amiss, like cracked stock, warped stock, bedding and crud issues, loose action screws while taking apart etc.
Even if it turns out to be a scope issue I would still tear the rifle and stock apart and check things thoroughly.

Hope this gives you some ideas.

Just to clarify things; I was hunting on my bicycle with the rifle strapped on my back, went around the muddy edge of a road-wide puddle, my tires slipped and I toppled sideways into the ditch, bumping my muzzle into the ground under the water. I had black tape over my muzzle as i usually do when in thick bush or wet weather.
 
Jerk the scope and make sure nothing else is loose. Then off to Korth for a once-over. If you have a spare scope that would be worth giving a try to rule out mechanical issues.
 
I had the same issue when my 'beater' rifle had loosened up the scope rings tiny screws, and also when it had loosened up where it attaches to the gun/base. Other than that simple possibility, and barring any obvious problems with the barrel (did you check the tightness of the stock/action screws?) I would say the scope is pooched..

x2 for trying irons or another scope..

good luck
 
Try a different scope. Tear the rifle apart and check for crud in the bedding. At first glance it looks like it's trying to double group which is usually bedding but can be the scope.

Your target shows how 10 shot groups will show problems that a 3 shot will hide. The next guy would have shot a few 3 shot groups; flukes a good one or two, explained away anything he didn't like as a flier, bad shot, gust of wind or the result of the wrong colour socks.
 
By all means send the scope to Korth. To me looking at the group without knowing the scope had a fall I would say a bedding issue. When the shots are strung horizontally It's often a sign of pressure on one side of the barrel either from the stock warping or something jammed between stock and barrel.

Pull the scope and check the front ring base screws to make sure neither of the screws are touching the barrel tenon threads. If they touch when tightened down this can make a huge difference to the grouping ability of the rifle. You make have to shorten the screws a thread or so. Simple fix but one very often missed.
