Poor man's bore gauge?

if I charged $5 for every bore I measure for someone else - both of my digital ones would have paid for themselves

if you really have no further use for it - i'd bet someone here would buy it for a few dollars off

I frankly don't know anyone who gives a sh!t about the bore diameter of any gun they own, so that sort of payback is out of the question . That said, assuming I decided to pop for one of these, what's a good length to get? And is it worth it to pay the extra $35 for digital?

its always the chokes they want to know about.

length wise - i like 18" a little room to spare if I want to completely measure a 32" set of barrels.

I like using the digital- but the draw back is - always remember to have a spare battery around. but I also have a dial bore gauge, and it works absolutely fine -

so the answer to that is - personal choice - no practical advantage

So excuse me for bein' dumb, but...you can measure the choke constriction with this as well, right?

yes. insert it from front of the bore and as you slowly draw it out, the gauge's reading will drop - so, the points of constriction is the difference between the inside bore diameter and the reading at the muzzle. you can tell the length of the choke by when the numbers begin to drop.


to use the gauge - you use a ring that comes with it to zero it - the inside of the ring is .700 for the 16 to 10 size. so when you drop the gauge in a 12 ga for example and it reads .029 that means the bore is .729. if it reads -006 at the muzzle - the choke is .035

simple once you have done it a couple times
