model 700 sst .300 ultr accuracy problem

hunter280man

I hav a hunting buddy with two rem model 700 sst 26" barreled .300 ultra mags. one shoots well and the newer one groups about 8" groups at about 200 yards. He had the trigger worked and it only helped a little bit. Tried several factory loads and a couple hand loads, no help. Did rem have a problem with some of their barrels? This one lookes gook in the rifleing and is cleaned every couple of shots so thats not the problem, help.

How maddening is this scenario? Start with the basics, bases and ring screws tight? Is his frustration to a point during the range session that he is jerking the trigger? Look at the crown of the barrel for damage. Switch scopes. Check the action screws for tightness, too tight can cause problems too. I've been there and the only thing I can say is try one solution at a time so that you can figure out what the problem was. Correct too many things at once and you may fix the problem, but leave it out there to bite you again. Good Luck!KC

Thanks Boltactionman, no its not the loose ring sindrome. Nor is it the trigger flinching, I can't hit a damn thing with it either. Now the scope? We've replaced the rings twice, first time they broke and the factory replaced them with blued ones to get him on a African safari, second time was the ss replacements after he got home a few months ago. Gun shot poorly with all three sets. Now the scope could be the problem, Im not sure what brand, possibly a sworvinski, I know he paid about 600.00 for it. We will rip it off and try another. Thankyou!

Have you pulled the stock and looked for any shiny spots where the barrel is hitting ?It's probably somthing simple / basic as boltman said.

hunter280man

Yes he had a good gunsmith take it down and said it was ok, then he worked the trigger, factory trigger was over 8lb. The gunsmith thought that possibly the problem might be barrel whip; too much caliber for the steel used. He didn't check out the scope, we didn't ask him to, never even considered the scope before today.

1)Get different scope & try.2)Aline scope rings with barrel.3)Glass bed 1" in front of recoil lug.4)Float Barrel.Any one of these can be very determental to accuarcy. I have seen brand new scopes not work right, so check this out first.

Also when shooting a new rifle that is giving you problems you might want to start the range at 50 yards, makes sighting a little easier.Another thought; try loosing the front guard screw a little at a time at each shot, but not to loose, if there is any differnce, then there is"bedding" problem. If the action is not fit good into the stock then when you tighten the screws it will put the stock into a bind and this will hurt accuarcy. Have been there and done that!

Hey thanx guys; gave the Kid a call already, we'll be working the bugs out probably in the next weekend or two. If its not a scope or bedding problems I'll be droping you'all another line, thanks again. Got to quit calling him the "kid"; he's 22 now. Any more ideas keep em comming!

while on ar15.com recently , i read a post about a bent barrel from the factory . remington asked the gun to be returned .i don't remember seeing the results.(if any yet) you mite want to call the factory and ask if there is a recall or problems they know of .the gun in question was a model 700 in 308 .if memory serves me it was premium gun (sst maybe??).in the pics supplied you could see the barrel starting off straight then turning left near the end of the stock at the foreend .hope this helps you out .

I can't prove this in court (haha) but that deal with the broken rings reminds me of the problems I had with B&L Elite 3000. I went through 3 sets of standard rings on a magnum gun. By the time I got done with them, found out my new scope was bad. I often wondered if the rings letting go caused to much stress and broke the scope?KC

hunter280man

I think we will lap the rings first then try one of my leapolds on it if this doesn't cure the problem we will work on the lug-glass bed-screw angle of it. I'm pretty sure the barrel is good as far as not being bent or stock clearance towards the forend. Its amazing how even though you may have worked out such problems in the past a person still needs advice from another perspective. For some reason I can't find the Remington site, does any one know the address?

here's a simple way to find a BAD bedding problem. Slide a dollar bill under the barrel up to the receiver, if it hits something, you have a BAD bedding problem. There may be a lesser problem where as the bill won't hit anything, BUT, under the flex of the barrel during the intense pressure of the UM bullet spinning down the tube, it could still flex and contact with a high spot in the stock. That's just a quick way to find a big problem. It may be less pronounced than that.

I was just thinking of problem a man had at a gun shop concerning a 700 BDL police model, in a 308. The gun would not shoot good so he gave the rifle to a friend of his to try & figure out what the problem was. After about 150 rounds or so and trying every thing possible they finally sent the rifle back to Remington and had a new barrel put on-presto! That was the problem.
