Need some gun smith

[Gus08]

Have a model 70-.270 pre-64 classic sporter 1998. For some reason cannot get it on paper probably have 30rds through it live on central coast.

[mtenenhaus]

can you perhaps give us a bit more information. not trying to be too simplistic but some thoughts:
1)Are you using optics (scope) or sights (adjustable or fixed)
2)at what range are you starting to try to get on paper....i generally start at something short like 25 yards and move on from there. It's a lot easier that way.
3)if you have a scope mounted, are the mounts secure and did you bore sight? By bore sighting you are removing the bolt from the rifle and looking down the bore at a target, then without moving the rifle..look through the scope and adjust it to see the same point/picture....that gets you close
4)is the barreled action secure in the stock?
5)are you using factory ammunition

these concepts will get you started and allow us to better help you

I did bore site it before I took it out to try and dial it in. I also started at 25yrds a walked it out from there. After no success I did take it to a local gun smith who is no longer in business and had him give it a looking over thought maybe the crown of barrel was damaged gun came back in his opinion in excellent shape

Clean the barrel and get ALL the copper out.When you think its clean,clean it again!

[Fjold]

Take your copper load and shoot it at 25 yards. If the bullets don't hit within an inch or two higher or lower than the aiming spot then adjust the scope until they do.

Then cover the whole target frame at 100 yards completely with a white paper, staple multiple pieces if necessary to cover the entire backer. Put a 1" aiming dot in the middle of the white backer cover. Shoot one shot at the aiming point and look for the hole, (either walk out there and look or use a 20X+ scope) Adjust your rifle scope to move the shot directly over the aiming dot and fire one more shot. Adjust as necessary.

Maybe the barrel needs lead removed from your first firing.

If you shot soft lead or undersized lead or lead without a gascheck you may have filled the rifling with well lead.

Is the barrel free floated or does it have contact with the stock?

Even a few hot rounds of lead will leave traces making the rifle less likely to shoot groups with copper bullets or jacketed bullets.

A good cleaning and then fire only jacketed to see if the problem is solved.

Good luck.

Try a lighter "California" copper bullet. As a general rule, equal weight copper bullets are LONGER than their jacketed lead counterparts, and require a faster twist. Ignoring this will almost certainly lead to a lighter wallet and a few gray hairs!

Do you know the twist rate of your barrel?

[Fjold]

Winchester Classic 270 Win has a 10" twist rate, the 120 and 130 grain copper loads will have no problem stabilizing. Barnes does their 270 Win bullet testing in a 1:10" twist barrel.

Do you have a friend you could have shoot it? Sometimes it's not the arrow, it's the Indian. Just weeding out variables.

[G-forceJunkie]

With a bolt action, you should be able to sand bag the gun up, pull the bolt, look down the barrel and adjust the scope to hit within 6-12".
