Well, i can relate to your problem. I have a Remington Model 700 VTR.22-250 also. I bought it brand new. For the life of me i could not get it to group,and it wasnt me. I have a Winchester model 70 .270 that i can shoot 5 shots touching@ 100yds with factory remington ammo!! So i did the same thing,tried several different factory ammos etc. Still could not get it to group. Not saying this should be the answer but i bought a Bell&Carlson Medalist Stock and put a Jewell trigger in it and it shoots awesome now. 5 shots touching @ 100 yards. If i can find the targets before and after i will post them.
