Need some help and advise

[oneyeopn]

that is a good one, my targets looked like that yesterday with my homebuilt but I was shooting offhand with BUIS and rather quickly. Is it possible that your reticule is shifting slightly? do you have the ability to bench and bag your rifle? Just to take the human part out of the equation! Put it into a lead sled, lock it down and see what it does, plus in my case shooting paper is way more nerve wracking than shooting vermin. Trying to make everyshot that perfect one can really apply stress to a person. the way the brass is coming out makes me think you may need a heavier buffer to get your rifle "timed" right. If the bolt is unlocking to quickly it can also change the bullets accuracy. Anyone else have any ideas?

Grover, I took my .308 kimber and my .308 Icon and shot them both....first two rounds with the kimber were touching and thrid round was close. Same story with the Icon...I shoot federal in them and they are both shooters. I did a little better with the Kimber because I have a 14 power scope on it vs 9 on the thompson. Its not my shooting...I cant match the group Reb had yet but I can do less than an inch...so I feel better that its no all "me" I have no doubt that the sport can shoot because you guys have certainly proven that beyond a doubt. I know there is something wrong but cant figure what it could be....you may be on to something on the buffer....I also noticed it throws the steel cases backwards and the brass more stright out perpendicular to the reciever.
I will figure it out eventually....maybe try some different ammo...are different springs available for the buffer? Where does you pitch the brass? By the way...if that had been off hand...I would be very happy LOL. I have changed the scope once but I can do it again and see if that makes any difference and could put the Nitrex on the kimber because the kimber is definately a shooter.

John. Both of mine if the buttstock is 6 oclock and the barrel is 12 oclock, both of mine throw the brass about 2 oclock, I dont remember if that is right or not, we have had discussions about it in the forum and I thought 3 to 4 oclock was right, I am hoping someone else will weigh in here because some of this is not making sense to me. the sports have shown a proclivity to be accurate rifles and yours is not. You may try the scope on different rifle you also might look at the muzzle of your barrel and see if any obstructions or problems are there. It is getting over my head (which doesnt take much )

 

[Buffalohunter60]

Ha, it was over my head from the first round. Maybe I will buy another sport and just switch everything over to it...but I really want to try and find out why its doing what its doing...I will check the barrel...I noticed the lock nut on the "stock" I wonder if I can increase the buffer tension if I losten the nut and screw it in a turn or two and see what happens.

 

[Buffalohunter60]

As a last resort...maybe I could send it into S&W and see if they can figure it out...I realize this comes with no accuracy guarantee...but only accurate rifles interest me...I never hang on to the ones that dont shoot tight.There has to be a logical reason this is not grouping...kind of a process of elimination........I can talk to my dealer and see if Smith and Wesson would consider looking at it, I am willing to pay for it so not looking for a freebie.

I do not think that screwing in the buffer tube will increase the tension, in fact it will probably mess up the buffer retainer. A heavier buffer and or spring is what is called for here. I think I would check out the scope either put a different one on the sport or put that one on different rifle. If there is a problem with it it is not much of one cause you are still definately within one minute of Bad Guy or Coyote. Just a thought plus remember that a lot of us are loading our own ammo now and if you look back at some of the targets people running factory ammo are grouping about the same.

 

[Buffalohunter60]

Yea, I know......I may have to start loading my own again, never used to shoot factory ammo, and I had loads worked up for every rifle and no problems....I tried that ammo in my CZ and I cant get it to shoot in that either and I was using remington in my CZ before and shot cloverleafs at 50 yds all day long.......I will try swaping out the scop, I have pleanty of them, the Burris on my Kimber shoots great and maybe I can put this one on the kimber and see what it does there...process of elimination....nothing else works...I will get another press and get back into it again. I will not be happy until I get this thing to group....what length barrel are you using? Are you using the sport barrel or a varmint heavy barrel?

 

[oneyeopn]

I am using the Sport barrel and I will use it until either I die or I shoot it out, from the wear testing on Melonite I will die first LOL...process of elimination is a good thing, now your on the right track.
