I'm interested in hearing thoughts about what I'm seeing when I borescope one of my competition rifles (Highpower across the course). It is an Obermeyer 5R in 6.5 Creedmoor. When I had it built, I didn't really have a smith, so I had the action maker fit and chamber the barrel. (Won't mention names, but rhymes with Fierce, and starts with a P). But I got worried when one of the guys called me to talk about the tight bore. I know Obermeyer barrels have tight bores, but they acted like they had never heard of Obermeyer or a tight bore and how it was soooo tight and they didn't know what to do with it. Anyway, so I get the gun back and have never been pleased with the accuracy, struggling to get any loads to keep under 1" at 200yds, more like 1-1.25" is average regardless of what I put through it.
Here are some photos of the throat area. I haven't scoped a lot of "custom" barrels, so don't know how much is normal in the way of tooling marks, but some is definitely not normal. Am I being too picky? Of course, if it shot better I wouldn't complain!
I appreciate everyone's help
This is a view of the throat with irregular tooling marks, and a fairly deep lengthwise mark
This is a sequence of three, from the throat area at upper left and going up into the barrel just past throat. The land is on the left, in the bottom of the groove are these clear gouges, and only in this one groove. This barrel has never had any sort of steel cleaning rod placed in it.
The last one is what looks like a long groove in the bottom of this one land, starting about 5" in the barrel and stretching a good 8". The lands are on the far left and right side.
