[QUOTE="J E Custom, post: 1177846, member: 2736"] Good point, Playing devils advocate is always a good exercise that shows a difference of opinion and will help some make a decision based on there needs. and encourage debates. But I for one have used mine many times to solve a mystery as to why a barrel doesn't shoot well or even why a barrel resist fouling. It also allows me to predict the quality and accuracy of a barrel before it is installed (to a point) and rule out any quality issues before it is installed Not everyone needs a bore scope, but once you buy one the education begins. Several of the problems that were resolved that were un-detectable with bore lights, were found with the bore scope were. A pre-threaded and chambered barrel that the chamber had been cut with a roughing reamer or one that had not been cut correctly and had no throat, leade or free bore and pressure would exceed SAMME pressures with starting loads. Another was a cut rifled barrel that had a skip in the rifle cuts about half way down that you could not see until the 90o bore scope was used. The rifling actually lined up with the groves at this point. The barrel was sent back for replacement with no problem. The list goes on and on so I could never do without mine. I also inspect all new barrels before installation, and re inspect them after break in. When buying used rifles, it is indispensable in my opinion. Just an opinion. J E CUSTOM [/QUOTE]
