EVOL .30 Paradigm barrel ?

[igolfat8]

I purchased a used Paradigm .30 and there is a tight spot in the barrel starting about 11-12” from the breech. Is this normal and perhaps where the choke is? After it gets by that then the barrel opens up again.

Used guns are not always the top shelf units that were produced in the factory. It doesn't sound like something that Tom would let go out of his shop. How accurate is the barrel? Is it MOA or better? Have you used a bore scope to look in the barrel at that particular spot? Tight spots can be from a number of things like being hard bent for whatever reason and then straitened, a building up of lead, a rough spot from manufacturing, rust/scale buildup, etc . All these can act as felt drag. A tight spot is easier to deal with (fix) than a bulge, that's for sure.

I’ve not shot it yet as I just got it and wanted to clean the pipe before shooting it. The bore was whistle clean but I just noticed an odd tight spot about 11” from the breech and wondered if this is the way all of the Paradigm barrels are made? I’ve not bore scoped it yet.

All that I can tell you is that my .30 barrel is as near to perfect as anything that I have seen. My Paradigm started out it's career as WolfmanGreg's gun and it was a .22 that had an accuracy problem. Greg sent it back to Tom, who confirmed that there was a problem with the barrel, and asked Greg if he wanted a new barrel in the same caliber or .30, and Greg had him change the gun to .30. That's why I bought it, I knew that if Tom was fixing his mistake, the fix would shoot perfectly, and it does. If your barrel has a noticable imperfection send it back, it's not supposed to.

Where did you get the gun from?
And how old is the rifle?

Shoot it and see how it functions, though there should be no tight spots in the barrel itself. I would reach out to Tom and see what he says. It may be something that he is able to fix, and he will get you taken care of.

Good move of cleaning the bore first. I bought one with a bulge and crack once, but it still shoots moa groups if I do my part. It's hard to say without looking or shooting what the issue is. It may need polished out or a bit more lapping in that one spot. I agree with Woogie_man, it needs to be checked out for accuracy by being shot at distance with a few ammo selections.

Bought it over on AGN and it even has the AGN logo engraved on the action. He said it shot 44s really well. I’m going to shoot it before I get to worked up about it. I just thought it was odd to have a tight spot in the middle of the barrel.

Bought it from Michael over on AGN and it even has the AGN logo engraved on the action. He said it shot 44s really well. I’m going to shoot it before I get to worked up about it. I just thought it was odd to have a tight spot in the middle of the barrel.

I'd bet it is a shooter.

I pulled zero lead out of it so it’s not like the barrel is fouled. I can always feel the choke, when pulling a PatchWorm through the pipe and that is what it feels like but I’ve never felt a choke mid way??? I’ve also never owned a TJ barrel (which is what I think this might be???) so I wondered if it was unique to TJ barrels?

I'd bet it is a shooter.

I hope so…

Shooter or not, it's not right. In his videos even Tom says that he designs his guns so that you don't have to do anything to them but shoot. That is the point of getting top tier +$3K gun. You shouldn't have to be working out tight spots in your bore, and frankly, I don't think Tom believes that you should have to either. That's why he stands behind his work. You are not wrong for caring about it, even if Michael didn't.
