hey guys sorry if I'm on the wrong area or maybe made thread that someone else has made before I'm new to the form and new to shooting in general..
question is ..

i have a tikka t3 3006 and i was shooting it at the range this weekend i was shooting 165s corelokt to start and i had a good grouping but i was planning to switch to the 180s corlokt due to availability ... but when i switched to the 180s they seemed to be all over the place.. is it possible for the 180s to not be good for the rifle? also for some reason through out the day my scope had slide forward 3/4" and my rings were tight! probably went through 60 or so cartridges on just the 180s and couldn't seen to get as good as a grouping on the 165.. you think i would be able to get something pretty decent though?
 
There are many reasons why you are not getting a decent grouping. You try to eliminate every possible reason that why it could be messed up.

You need to fix your scope
You need to make sure you are on the same exact shooting position
You need to make sure weather conditions are the same

Testing different cartridges on the exact same conditions will let you find the best cartridge for your tikka

My Tikka shoots 150 much better than anything else.
 
First and foremost, you need to have your scope secured in proper position.

Are you shooting Remington factory ammo or reloading Corelokt bullets?

Aside from heavy winds, weather should not be a big factor.
 
Fix scope issue first. Either new set of rings or you have the wrong rings (30mm vs 1") or they're just crap. I like Talley's - period! But it is possible your rifle just likes the 165 bullets better than the 180's. And you might find that another brand of 180's will shoot just fine.
 
My Tikka T3 270 will shoot just about any 130gr bullet well and just about any 150gr bullet poorly. I'm talking 1 1/2" groups compared to 2 1/2" groups. First of all get the scope straightened out and then try it again. The 30-06 was made to shoot 165gr bullets so maybe you just need to find a supply and stock up.

Try and find the torque specs for your rings and tighten them up accordingly. You could also try using some Permatex High Tack that can be bought at most automotive stores. Spray a light coat on before you drop your scope in and tighten it up.

Hope this helps. George

As you know, your scope rings are loose and need to be tightened; using green threadlocker to ensure the screws don't loosen after tightening doesn't hurt either. You can tighten ring screws in one of two ways, use an inch-pound torque wrench set for 15-20 in-lbs, or hold an appropriately sized screwdriver between your thumb and first two fingers, so the screwdriver hangs straight down from your finger tips, in this way you won't overtighten the screws. The screws that hold the ring to the rifle, I assume you're using ring mounts rather than rings and a base, should be torqued to about 30 in-lbs.

If the scope has turned in the rings, ensure the vertical wire is vertical before you tighten the rings, and not grossly canted, or your sighting adjustments won't make sense. You don't need to be anal in this regard, if you look at the reticle, and line up the vertical wire with the center of your cocking piece, that's good enough. As you tighten the rings, pay attention to the position of the vertical wire to ensure the scope doesn't turn as the ring tightens around the tube. Some rings are worse than others for rolling the scope as they tighten. As a last step, you can put a small drop of nail polish on the rear edge of either ring so that any movement of the scope will be immediately obvious.

Talley one piece rings is your answer. I had scope slippage on my t3 until I switched. Laser beam with 150's or 180's.

Tally LWs are very good mounts. I have a set on my T3 and other guns. They work well but are not the only dependable mounts available out there. It sounds like improper installation is the OP's problem.

The first thing to do, is fix the ring issue. How many shots are you firing in each group, and what size are the groups with the 165's compared to the 180's?
 
Give us some more description.. what's a good a group to you what's a bad group? Give us measurements of the group sizes, brand of scope rings. Shooting from a rest ? human error for grouping size?... anyways lots of factors to consider. I had a Tikka 30-06 that loved only a certain factory load and it hated everything else, while testing many different factory loads with this gun I found groups opened up once the barrel heated up and it didn't take much 4+ consecutive shots it would open up then i would have to wait for it to cool down. Tikka has a light barrel I found and heated up quick. Make sure the action is sitting in the recoil lug in the stock. Some guns can be very picky some like certain loads some like certain torque specs, some like clean barrels and some like fouled barrels.
