How do these barrel crowns look to you?

[Turkeygetpwnd38]

I had two barrels chopped recently by a local smith. I've been chasing down flyers and groups ever since with one of them (Seekins). I am just trying to narrow down what could be the issue. I don't want to make problems where there are none and I am not super knowledgable about this stuff. I'm usually an off the shelf, shoots good enough guy. I'm hoping nothing is wrong and it's just me but you more experienced guys, how do these crowns look to you? I did the Q tip test which is what I found recommended on the interwebs, both catch a little.

Another odd thing is both shoot better with my TB Dominus on vs a Raptor 8 I have. The Raptor changes POI a lot, like a foot high and left, and groups awful with the Seekins, opens up groups but is more consistent on Kimber. This wasn't an issue before. I'm going to the range again in a few days and will check the raptor on a control rifle to see if it is the suppressor or not.

Kimber shoots OK, not as accurate as before the chop but consistent groups, albeit a little larger. Main issue is Seekins. I included pics on Kimber just because it was done at the same time by the same smith.

Both rifles were checked with multiple proofed scopes, every screw torqued, etc.

If you need better pictures let me know, I tried to get the best angle I could with lighting.


First rifle- Seekins PH2 6 Creed, cut from 24" to 18"








Second rifle- Kimber Hunter 280AI, cut from 24" to 20"

Nothing looks wrong...but I will normally look for a burr on a crown with a qtip...it will pull the fibers off the qtip if there is a burr there.

Yea each barrel has a spot that pulled the qtip

Rings, bases, action screws tight?
Have cut a couple with a hacksaw and no cleanup work with no changes in groups or zero.

Everything torqued to spec and double checked. Even swapped scopes to confirm. Kimber shoots OK, just not as well as before. Seekins is the one that I’m getting inconsistencies in groups.

Leupold scope?

Have you tried filing that burr? That’s frustrating bud.

Honestly hoping that putting more rounds downrange will smooth any out, not sure if that's a thing but I guess we will see Complicates things a little with the raptor suppressor, I'm not sure if I have an issue there or not but should get answers on that Thursday.

I just wanted to know if anyone with more experienced eyes saw something I didn't

A lot is made out of a perfect crown, when in reality it is only important for round #1 out of the new barrel. We aren't shooting .001's.

I'm not a chamfer crown fan....but there's nothing there that looks like it is your culprit. If the bore was a bit less tight where it was cut it can do that.....but the odds of it happening 2x are not good.

Can you have someone else shoot it, preferably someone with experience shooting light snappy rifles?

Thanks for the input. I have experience shooting light snappy rifles.

Like I mentioned, the kimber shoots ok, it’s the light one. The Seekins is almost 10lbs so not the most difficult to shoot. I’m going to continue messing with it, it might be a suppressor issue.
