Hi all, I just received this gauge in the 12/16 config. My question is: Should I have gotten a zero ring for 16ga or does the .700 ring cover both gauges? If there is just one ring, is there anything special you need to do to measure a 16 bore?
Thanks all!

I have the Skeet's bore mike for the 10, 12, 16, 20 and 28 gauges. It has two setting rings, one is .700 and is for the 10, 12 and 16 gauge. The other is .600 and is for the 20 and 28 gauges.

Knowing that nominal 16 ga is .662" when you set your gauge to check a 16 instead of setting 0 you could set at +.038 then read direct from the gauge the relationship to nominl bore dia. Keep in mind if checking an early L C Smith they bored the 16 to .650". PS; I don't actually have a "Skeets" but as a machinist have used numerous dial bore gauges. I am assuming this uses a standard dial indicator having .100" travel. Of course with the .700 setting anything larger you simply read as .7xx while if it is smaller you can then read as .6xx which would really be the best way for the 16. some dial indicators do have secondary numerals reading opposite direction, don't know if the Skeets does or not. If so this is where seting 0 in the bore would be handy for reading the choke as would read direct amount of constriction on the secondary numerals.

Miller, The Skeet's I have, an older one, the needle travels both +/- and will travel .500 in length. I had explained what you had said to Greg about re-zeroing once you found out what bore size is and then setting to zero and read choke which would be reading in minus readings now (unless bored out). I find this easier to read than leaving dial set at the ring (.700) reading bore and then subtracting as it is coming out from choke area. Much easier to re-set to zero inside of bore and then read choke area. JMHO

JDW, I disagree with your method. It is much more professional to give a buyer (or your files) a correct measurement of the area of the bore you choose to measure. You zero the gauge, and read the measurements at the correct number. A .665 bore is a .665 bore. A .635 choke is a .635 choke. Your gauge should remain at zero when it goes into the testing ring.

Bill, I agree with you that the correct way of describing bore and choke is with measurements for both as you've described. But you can get there either way. If you do it JDW's way, you just subtract the choke reading from the bore reading, and you have your numbers, i.e. (.665-.030=.635) Different way of getting to the same place. Of course, there is always the possibility of losing a .000 or so in the process, but in the scheme of things not really relevant.

If the bore or choke gets changed in the future, JDW's method does not give any information about what was drilled out, the bore or the choke. If you just give choke (difference between bore and muzzle), the buyer or the owner has no idea whether the bore is of the original factory dimension. I can have a .750 bore and .030 of choke under JDW's system and it would indicate a nice improved modified choke. Unfortunately, in most cases, it also indicates a ruined barrel, both in the bore and in the choke. It is better to give the true measurement of both bore and choke. Don't mess with the zero on your micrometer after you set it with the ring.

Where do you buy a Skeet's gauge other than midway? Does Skeet's have a website or phone number?
