I brought a second hand 22.250 remmy 700 varmint fluted last week. Tried zeroing it over the weekend and all is not well. Long story short it won't hold a zero. It throws bullets all over the place two to three inches apart. The only way to get it to shoot in the same place was to do a cold shot, even then it wasn't consistent and then don't shoot it till barrel cold again. Even at a zero of 25m we couldn't get a tight group and I'd expect hole in hole at 25m. I tried some other ammo, still no better.
Perhaps I've been foolish. I have now noticed after market stock and barrel are touching and I can't slide a bank note more than an inch along the barrel. The barrel has been screw cut and there is hardly any crown on the rifle. The barrel just ends really. I'm no gunsmith but guessing these two issues are a factor in the poor groupings.
For the record my other rifles shoot much straighter so hopefully it's not me.
Any suggestions, thanks.
