7mm Sight in help

[bobcat]

There's a gunsmith in Lacey who might be able to install a new barrel. He's definitely capable, but apparently his preference is to do only complete rifle builds. It's just a matter of if he has time to do it. So if you can't find anyone else at least try contacting this guy and ask if he's got time for a barrel swap.

My 7 mag was throwing rounds a couple years ago. I think I had a bur in the rifling but never scoped it to check. I cleaned the living heck out of, literally ran a bore brush down it like a 100 times. But I also switched ammo from Winchester to Barnes. She shoots tight now. Same type of set up, but an old Ruger M77.

Not sure whats up with your pic of the round fitting in the barrel though. I cant imagine the barrel wearing that much. You either don't have a 7 mag barrel or don't have 7mag rounds..I just checked my 7mag and it stops about an 1/8 before the casing...

The guys at the range thought that it might be a different barrel because you could actually wiggle the bullet around inside the barrel. They are definetly 7mm bullets straight from factory. Might be worth changing ammo but think I'll get it checked out first before spending more money

It looks to me in the picture that the barrel is not actually touching the casing.  It appears to be stopped just shy of the cannelure ring.  This would imply to me that it is stopping on the ogive    which would then imply that its the proper size barrel

[Karl Blanchard]

Like Bullblaster said, find out where the ogive is on that loaded cartridge before you go ripping off a barrel.

[Karl Blanchard]

That's the cannelure ring right there.  Looks to me like it is clearly not touching the casing.  Am I blind   I very well could need glasses.  That's a real issue in my life right now

You would think more than just a tiny bit of the jacket would engage in the barrel. My mini 30 bullet would only go halfway down the bullet before touching

How old is that rifle, looks like some pitting on the outside of the barrel?
Is the rifling still good?

It all depends on seating depth and where the ogive is.  If the bullet is seated deep in the casing than the ogive will be much closer to the case mouth.

Idk I think it's from the 70s. It has a little pitting on the outside but not to bad it's been hunted with. You can see the rifling if you take the bolt out and look up the chamber. The end of the barrel you can see light rifling

it depends on bullet shape. There is lots of bearing surface down into the case neck or below possibly. Anybody can seat a bullet so that it won't leave much bullet between the case and barrel on your "test"

[bobcat]

I would try different rings and bases, and a different scope, before replacing the barrel.

[Blacktail Sniper]

Try finding a gunsmith that can slug the barrel then measure it. 

Then you have a better idea of what size/caliber you have.

How many times do you think the rifle has been cleaned?
