hello. im new here and this is my first post. i have a 700 stainless 223 varmint rifle. when i first got it it jammed really bad to the point sometimes i had to beat the bolt with something to open it to release spent shells and would misfire sometimes and all the shells had a deep scratch down the side like it had a metal burr in chamber despite multiple cleanings i couldn't fix it. so i sent it back to Remington and they rebored the gun and put a new bolt in it. since i got it back it operates very good. no more jams and fires every shot however it shoots all over the place. I've tried every kind of ammo i can find from 55 grain Remington fmj , ballistic tips, federal, winchester 62 grain, etc!!! nothing will shoot a group better than 5 inches at 50 yards. the scope is a 3-9x40 nikon bdc. it is mounted solid and there is no give or play in scope mounts. scope was new when i installed it. I'm at a loss. this gun should be a tack driver and i don't trust it enuff to even hunt with. I'm gonna try the scope on another gun tom to make sure the scope isn't defective but i really don't think it is. i believe its the rifle. has anyone else ever had this problem or heard of a gun scattering bullits this far off? i love the gun and have a huge farm which i would like this to be my daily rifle to carry but i cant until i figure something out. any suggestions? should i send it back to Remington or just call it a lemon and trade it off for something else. it was a gift and has some sentimental value so i really wish i could get it right. I'm aggravated and at a total loss. not to mention have spent a fortune on shells. i did the break-in with cold barrel cleaning after each of first 5 shots then shooting 5 then cleaning etc. I've done everything right but it just seems to be a terrible shooting gun and have never heard of that before. anyone else? oh also im using a caldwell lead sled on a solid bench to shoot off so its not human error. its steady and humanly possible when i shoot. actually better than i can hold alone. so thats not a factor either.
