What would you try next?
« on: September 14, 2007, 08:59:05 AM »
I recently bought a new Ultra in .223.  It has a 1 in 9 " twist.  I've shot approximately 200 rounds of various brands and weights of bullets.  The best I can do is 1 1/2 in. groups at 100 yards with Black Hills 77 grain match bullets.  I've done the O-ring trick, I didn't remove any wood from the forearm...it seems like it maybe tight right next to the hinge.  1 1/2" isn't acceptable to me for a varmint rifle.   The trigger is clean but heavy and I'm thinking that might explain some of the vertical stringing I'm getting.  What would you try next with this gun?  I really like this gun for some unexplainable reason, but it's got to shoot better.

The FAQs and Help sticky has the answer for the most part, shoot it with the front rest under the hinge just ahead of the trigger, that's a requirement pretty much without bedding the forend, if that doesn't improve groups, shoot it without the forend to see if the forend is the problem, if groups tighten up, the forend needs work, there are several options on how in the FAQs.  ;)

Quick, I started shooting it with a "butteryfly" bag under the hinge.  Last trip to the range I tried a bipod on the front and shot better...that one confused me.

Parts Man, that's what I'm after!!!  Making me drool!  I know mine has the capability...the bore is a little rough, I've tried polishing it with JB.

Not always, but when you string vertically it is the gun or loads, generally. When I am string vertically I try to add powder if I can, if not then I take some out to see if it solves my problem. Horizontal stringing is sign of trigger pull or shooting technique (or a lot of wind). If you do not hand load or different amounts of powder do not work, then I would look at the fore end for trouble, as Tim has explained. ;)

I had the same thing. It will shoot -2" with every thing else I put in it.
Very exiciting to find that load.

The best part is Federal's American Eagle 55 fmj are the same point of aim.
Not nearly as tight of group but I don't have to adjust my scope to shoot cheap stuff.

                 Try cleaning the barrel really , really good. There might be some roughness that you can see. If you can't see anything try running a patch with Hoppes #9 down the bore and let it sit a while. then run a dry patch down and see if there's any copper in the barrel. If you have trouble getting all the fouling out you might need to switch to something more aggressive like Sweets 7.62 cleaner.

Oh boy some body send him one of these and we will get the answer to the million dollar question on the other thread.
If ya been shooting a lot of jacketed stuff use some wipe out or other foam cleaner and if it keeps turning blue you got copper fouling.;D Kurt

If you do not hand load or different amounts of powder do not work, then I would look at the fore end for trouble, as Tim has explained. ;)

Actually, I would disagree with this statement.  As I was taught in the USMC, vertical stringing is usually caused by breathing.  In my personal shooting experience, if you you are stringing the shots in a consistent pattern and in a specific line (either vertically or horizontally or diagonally) and are breathing properly, then it is usually a mechanical problem...i.e., heating up the barrel and causing undue pressure points or an inconsistency in the methodology of shooting.  Believe it or not, a lot of loaded rounds would be saved if the shooter would take the time to time to dry-fire the weapon and learn how not to exert undue or inconsistent pressure at the moment the trigger is pulled.

If the grouping is erratic, it is then I would start looking at velocity variations, load consistency, barrel problems, etc.

Just remember that it sometimes isn't the "dope" on the weapon but the "dope" behind the weapon that causes a majority of problems.
