Barrel burned out? Or bad smith?

[light rain]

I bought a remington 700 270 from my shooting buddy. The gun is older than I am I think! He is an honest man who is helping me with long range shooting and reloading. He and I are stumped. He bought it to build on 30 years ago and never did. So story is.... A cop had it built for a sniper rifle, when he went to get ready for sniper school he was informed he couldnt use a 270 it had to be a 308. So he had another built. My friend bought this one and was told it had less than 200 rounds down it. He never shot it because he thinks the smith ran the reamer in it to far. We loaded nossler 150 partitions and berger 150 vld in it and it shoots a 1 3/16 group at 200 meters 10 thousandths off the lands ( I am knew so if I mess up terminology bear with me) The bullet is seated but barely, best example I cant get smk 130 g to seat without being 15 thousandths off the lands, I cant seat them any further out. They shoot 1 7/8 at 200 meters.
SO the question is did the smith mess up? Is the barrel shot out and they lied? Or is it set up to run the 150 grain bullets?
My next issue is, it is a heavy mtu barrel. To heavy to carry hunting but 270 isnt really the choice caliber for long range shooting so do I keep it as is maybe have a smith set it back? or scrap it and just use the action?
What do the experts say?

bring the rifle to a reputable, legitimate rifle builder in your area and let him or her look it over. Or, buy a CerroSafe chamber cast ingot (Brownell's has this) and make yourself a cast of your chamber and see what you got.

And for sure you need to figure out the bore twist rate, which is easy. Just use a tight-fitting patch in the dry bore on a cleaning rod with a ballbearing handle. Once the patch is fully into the rifling and the rod starts turning, mark the rod on top near the handle with an ink pen. Make the mark a dot. Measure how much rod there is between the handle and the back of the action. Then keep pushing the rod into the bore until the dot comes back around to the top position. Measure how much rod is now sticking out of the back of the rifle. The differences is your bore twist, such as 1:10" or whatever it might be. Bore twist will help determine which loads will shoot best in your rifle.

Toss that problem barrel and have a new one installed, and get to shooting...

Could be nothing more than it doesn't like 150 gr bullets. Quite often, you'll get better accuracy out of 140's in a 270. With that said, under 1 1/2" group at 200 yds+ with partitions really isn't bad accuracy. That's under 3/4 minute with a hunting bullet not noted for gilded accuracy.

Pay me $150 and I alone will tell you what happened. For an extra $25, I can tell you how the next barrel will perform!
