Pulling my hair out...CZ 550 .243 accuracy issues

I'm at my wits end here. I bought a new CZ 550 .243 last Spring and put a Burris Fullfield II scope on it. From the get go, the gun produced shotgun patterns at 100 yrds...I'm talking 4-6 inch patterns. I took it to a local 'smith and he glass bedded it and relieved some wood from the stock on around the forearm (wood was putting pressure against the barrel).

This weekend, I decided to shoot some. I was shooting Federal Premium 100 gr. BTSP. My first three shots were 1/2" @ 100 yds. but 4" low from a clean barrel. I adjusted the scope and my next three shots grouped about 2.5 MOA and all to the left. From there, the groups opened up to anywhere from 2" - 4" patterns and never hit the same area of the target. I had a friend shoot it and he was seeing the same thing...Therefore, I don't think it was my shooting.

Anyway, I put it up yesterday in frsutration and decided to shoot it today (after cooling off and having a fouled barrel with 18 shots down the tube). Today, my shots were no better and once again were 3" groups. When I came home tonight, I checked the rings and everything was tight....However, I did noticed where the stock upon closing hits the stock inside the inlet'ed area when fully closed.

So what do you think is going on here? Could it be a bad scope? Could it be it doesn't like a fouled barrel? Bedding be an issue? Several people watching me shoot mentioned how loud the gun was and said I needed to check into that. I'm so frustrated right now that my thoughts at the moment are that I'm going to get rid of it and get a Remington CDL. This is the first gun to ever give me these kinds of fits as all my other guns (Remington, Winchester and Ruger) stay on the money. I don't think I'll ever recommend another CZ product to anyone (even though I do like the CZ 452 I have). Anyway, any information appreciated.
 
From what i hear, so im not swearing to this, the cz's wood stocks need to have the bbl rebedded. Something about the left/right side of the stock touching the bbl, and on the other side be free floated, or something along those lines.
 
Yes, it sounds like a bedding issue. Was the stock touching the barrel after the gunsmith worked on it? The less you remove a bedded action after bedding the better. Also, has the action screws been kept tight? Check the bedding to see if you can see something that might look like impact points. put the rifle in a sturdy vise and see if you can move the action or barrel around.

Sometimes you just get a bad one...JOHN /ubbthreads/images/graemlins/smiliesmack.gif
 
To answer a couple questions. Yes, the left side of the stock was touching before I took it to the 'smith. You could not slide a $1 bill under the barrel without it grabbing at a certain point in the stock. That has since been corrected. I have not checked the action screws which is a valid point. I also have not tried different glass which is a valid point as well. The part which makes me so mad is that I think this gun has potential since I was able to shoot a 1/2" group. However, I don't know that I'll ever have any confidence with this gun since I have had such a rocky past with accuracy. If is was a barrel heating issue, wouldn't I see my shots stringing? I thought this originally but theey aren't stringing....Just erratic.
 
Personally I wouldn't knock myself out over it - just sell it, take the loss if need be, and get a good shooter!
 
I think you should reclean it and see if you get the 1/2" again. if so, I think this means there is a machine bur somewhere that is picking up copper fast, maybe in the crown area. also don't just try one ammo, another thing is some lightweight sporter barrels like forearm contact, you might try putting some business cards under the forearm if the above doesn't check out
 
steve,
I tried several different brands of ammo (Remington, Winchester and Federal in anything from 80-100 gr) and never had one group well. I'll try the trick with the business card.
 
Hunt if you try the bus. card trick you should have 4-5# of pressure on the forearm. Before that try this take your sling off and set up to shoot with your bags or whatever front support you have behind your sling stud this should keep the pressure off the barrel if still poor then insert cards. Also make sure when your rifle is on the rest that the sling stud is not contacting the barrel.
NOTE: try remington corelock 100gr. for factory ammo in my 6mm that is a great round
 
On another note, has anyone seen or heard any problems with Burris Fullfield II 3-9x40 scopes? I have one of these on the gun and I'm wondering if that might be the issue. The first three shots were excellent until I turned the turret. What do people usually see when a scope goes bad? I have never had one go bad until maybe now.
 
Personally I don't care for Burris. I have the "free" spotting scope that came with a Fullfield II 3-9x40 and the clarity sucks. I have heard that scope and the free spotting scope is NOT made in America unlike most of their other products. Also while comparing a Bushnell Elite 3200, Nikon Prostaff and the Burris the Burris came in a distance third in clarity at Gander Mountain.

Also when others here mentioned "glass" I believe they were talking about your scope not the bedding.
 
The first thing I would try would be a different scope. I had a brand new Simmons Pro 50 go bad, thought it was the gun at first but it was just that the scope was junk.
