Thank You I pulled the post.

In the old days if you wanted a 2 inch diameter barrel the barrel maker would take some 2.250 barrel stock and deep hole drill it. After that they would put it between centers and profile the barrel down to 2 inches.
What that would do is keep the same amount of steel all around the bore.
Naturally they would then ream it and cut grooves and lap it.

Today with the availability of better drilling processes if you order a 1.250 barrel they drill a 1.250 blank then ream it without worrying about the drill wandering off center.
That is what happened in your example and you can measure it with calipers on a 338 bore.
As Randall pointed out the drill wanders internally as well.
You can put a light down the bore and rotate a barrel and watch the shadow in the bore. Quite an eye opener.
If the barrel is just bent most of the bigger gun companies will straighten the barrel and send it back.
In your case the drill wandered more than normal and after it heats up would continue to walk shots to the thin side of the barrel.

Gunsmiths like Bill Calfee will evaluate every aspect of a barrel before they will install it. If the bore is off center X amount it goes back. If the muzzle doesn't have enough taper it goes back.
His guns also sell for more money used than the day you bought it.

Very cool/detailed info. I'm sure his firearms are slightly above my budget at this point but we'll see where the future takes me. I'd like to see how tight I can get this thing to shoot at 1,000 yards + with proper case gauging and load recipes. Any suggestions would be great noting that each chamber/barrel combo might be different from the next even on the same model rifle, etc...

It's not that the barrel is drilled crooked.
It's that the barrel is curved.

Once you are zeroed at 100yds, you really don't need any additional windage adjustment to be zeroed at 600-1000yds unless you intend to dial windage to correct for wind.

per the supervising manager at Savage, the barrel was not crooked, it was drilled off center as they could easily measure the discrepancy with a caliper measurement tool at the chamber end and muzzle end. In other words at the action end of the bore, the left side was wider in measurement from the outside of the barrel to the beginning of the hole that was drilled vs the muzzle where the measurement was shorter in width. The hole that was drilled was not centered in the barrel (this is per the supervising manager at Savage) Obviously you have a depth of experience with firearms, I'm just stating what Savage explained to me. At the end of the day, the replacement barrel is shooting sub MOA at 100 yards so I am a happy camper

Ok, I see your point but at longer distances (i.e. 500 - 1000 yards) How much offset would I have needed? I mean my windage dial bottomed out at 25 YARDS. I was under the impression that those off center rings were more for off center screw taps or an off center rail. If your barrel is drilled from right to left (bore to muzzle) then the problem only amplifies at longer distances, no?

Glad to see your rifle is back and shooting well.
On an earlier post you said you couldn't offset the rings because the barrel was bored off center. The reason those rings are made is because 99 and 44/100 of barrels are not concentric end to end.
The offsetting of the rings takes care of that and other issues.

I have yet to shoot the SSS trigger. I received all the parts but the safety detent spring and the safety bar are not pinned yet.
In talking to one gunsmith he doesn't think they need to be but I want this one done right.

Hey Randall
Is that safety detent supposed to be pinned on the newer models?

[LynnJr]

It shows the rifles potential. Anything you do at home is now the ammo the shooter or the conditions.

They do their testing in a tunnel with the action bolted into a machine rest like a rail gun.
It better be a 1 hole group!

That's cheating

Still, would be nice to know what ammo it is. I would want to know if I was.

Good to hear everything worked out. You might want to ask Savage what ammo they are using considering that it looks like it just shot a 1-hole group.

interesting...ive never heard of either being or needing to be pinned but im not a smith just a basement builder.

i think youll like the SSS trigger much better than the accutrigger...lotta guys like the accutriggers but i never cared for them...to inconsistent.
