i have a parker hale model 1200 chambered for .308 and i'm experiencing Irratic Point of Impact? in a five shot group, three are touching and two hit to the side. my best group is about 2.5 inch at 100yds. someone suggested a buisness card or two under the barrel but that made it worse. i tried imr4895 and imr3031 and the results are very similar but imr3031 groups slightly larger. i am using sierra pro hunter 165gr bullets. and thoughts or suggestions?
 
There's so many things that can go wrong that could cause that. Check the obvious stuff first, like sights or scope mounts loose, action screws tight, barrel not touching the stock in some manner it wasn't intended, barrel crown undamaged, bore looks clean and sharp riflings. Try some factory ammo to make sure that's not the problem. Swap scopes with a known good scope in case that's the problem. Try allowing the barrel to cool completely between shots. You can burn up lots of ammo sorting out a problem like this some times. I know from bad experience.

X2 and once you've done all grizz suggested try a different weight of bullet. Shoot some cheap white box Win. Not loaded hot these group well in most guns.
 
My brother-in-law has the same gun and experienced the same problems. Found out that his stock had cracked (inside) - dried out, crappy wood, not sure.

He installed a plastic Ramline stock and it was worse until he had a gunsmith bed the rifle. Then the gun wouldn't shoot the same load as before. We tried a bunch of loads then I told him to try three of my hunting loads (for my Ruger). 165gr Sierra HPBT Game King, Winchester brass, F210, & 43.0gr of IMR4064.

Now when he misses, we know it's not the gun's fault.;):D

Good luck & I hope you get it sorted out.

I have found that alot of Parker Hale rifles, the barrel will be touching the wood in most of the barrel channel.
Free floating has always helped to improve accuracy, you may have to try several bullet weights to see what your rifle likes.
Check all the obvious stuff like the guys here have posted already.
I find that most European made rifles tend to like heavy bullets, so starting with 170-180 grainers might be helpful.
 
Sounds like a bedding issue take the rifle apart and check under the recoil lug and also at the tang area Parker Hales are prone to cracking stocks I would also free float the bbl.
