Just have to post some things that I have learned since acquiring a hawkeye borescope.
IMHO a serious rifle shooter cannot be without this invaluable tool. Figure many here know the benefits but will list most of them for all who are interested.
Obviously the bore can be examined for cleanliness or flaws. Can't tell you how many barrels told me they were clean based on the color of the patches to actually have carbon or copper still clinging to the barrel in a few hard to remove areas. A wonderfully accurate 6mm-284 suddenly began to shoot poorly doubling the group size at 200 yds. Inspection showed a black substance in the grooves a few inches from the end of the barrel. A few tight patches with Iosso it was gone and the groups returned. You can truly tell if what approach works to clean a particular barrel.
Several friends had problem rifles that they thought they had burned out. One memorable one had speed bumps of copper. Once the copper was removed it shot just fine.
The crown on many rifles looks fine even when using some pretty high magnification jeweler's loops WITH a magnification light. Run the bore scope around the crown area and you see a totally different scene!
Even the tinest irregularity can be discovered. This has me wondering how many shooters have been disgusted with a rifle's performance viewed the crown and deemed it good. I also wonder how many gunsmiths THINK they have the crown cut properly?
If you do you own gunsmithing when chambering you can view the throat area and see if the reamer cut straight by looking at the starting point for each of the lands. You can also inspect a crowning job.
You can even inspect a case to see if the web is getting thin before you have case separation issues.
I just had to share. Today I inspected two rifles for friends and both had imperfect crowns and one was thought to be clean. This got me to write this thread. I feel that if you are trying for perfection in your LR shooting you should part with the money for this essential tool. It unlocks mysteries.
Are there others that have a borescope?
