Maybe some of you gun guru's could explaine why the 7400 is so inaccurate and the 7600 a shooter.

I now have a 7400 in 270 win and my old 7600 30-06.I have not shot the 270 yet and was wondering if there was something I could do to make it more accurate.
How bad is bad,2-3 inch groups at 100 tards out of the 7400 or is it worse?
The desing is about the same,but ones a pump and one a auto.
Info please.

I don't know. I have an old 742 in 30-06 that shoots 1 1/2" 3 shot groups at 100 yds. While my Sako L691 shoots 1/2" groups at 100 yds, the groups with the 742 are more than adequate out to 200 yards, which most of my shots are within. I haven't ever shot a 760 or 7600 so I don't know how that compares. If you want groups less than 1" at 100 yds, get a bolt action or single shot, not a semi-auto.

I never knew they were so inaccurate. Where did you see that? I have one in a 270win. I had POI changes. It would shoot an honest 1.5MOA but my complain was POI changes. I finally figured out what it was. The new forearm I put on it was a tad too long. Which forced the pressure up on the barrel when the screw was tightened. I took a shim and put on the end of the gas tube to make sure the forearm wasn't touching the action. Then all was good. I never have, but plan on taking a dremel to it and taking off some of the forarm instead of the shim.

I bet I have over 500 rounds thru the gun. I have had it since 1988 relatively trouble free. Can't complain. Only issue was building a load for it. I had to pick my powder to make it cycle correctly. But also had to do the same for a Browning semi. I tried all the 4064 and vargets (fast burners Sierra recommends), and wouldn't cycle good, so tried 54gr of IMR4350 with 130gr gameking and shoots and cycles great.

Big Country,
I had just read alot of stuff about the 7400 as being in accurate.If i can get 1-1/2 groups with it thats would be great.I was a fraid of shooting it and not being able to hit the target.I have heard they sometimes don't group under 3-4 inches at a 100 yds.
Another question for you BC that front screw needs to be tight right?It was loose so I tightend it up,I don't have a manule for it so I'm winging it till I do.

Grizz,
I have many guns this is just the first 7400 I ever owned and I was just going to plink with it,or shoot coyotes and maybe some deer and antelope.This not going to be a primary gun,I plan on giving it to a nephew.
I just found it funny that I can get 1" groups with my 30-06 7600 and would not be able to obtain that with a 7400.
Thanks guys

Whether the front screw is real tight or loose shouldn't affect POI.

One way to see if you are putting varible pressure on the barrel is to put the forarm piece on. Now without the screw in, are you able to move the front of the forearm off the gas port (peice you are screwing into). All the pressure (or most of it ) should be on the gas port. The rear of the forearm should be just barely touching the action. There should be pieces of metal there near the action that holds the forearm on. Let me know if this helped you.

No the forarm is not touching the action,I see what you are talking about the 2 little clipps that are bent funny (just under the action bars)hold the forarm in place till the screw secures it,the barrel is basicaly floating.
So now I geuss I have to get some shells and light'er up.
Thanks

First off every 7400 I have shot sucks with coreloks. I had decent groups with winchester power points when I shot factory. Got great groups with 130gr gamekings federal factory.

I had no real luck with the corelockts either. The best for me was federal 130 noslers. At 100 yards you could keep under 2 real easy. At 200 it was finicky with anything but federals. CHoose ammo wisely! EJ

Ok thanks,I WAS going to go buy some el'cheapo core-loks,wellI geussI will try the federal classics 130 and the 130 BT Premiums.

Haven't had one yet that was inaccurate and the same goes for the 760/7600 rifle. I had some bad luck with ones extractor but that happened right out of the box and it was repaired.
