1. We have added the ability for anyone to 'bump' threads that they have created. This is mainly useful in the classifieds area where posters constantly bump for sale threads to bring it to the top. This allows them the ability to do that without having to clutter the thread with extra 'TTT' and 'Bump' type posts. To bump it, go inside your thread and click on 'Thread Tools' at the top, then select 'bump'. You can bump only once per 24 hour period.

    For more detailed information please see this post: Thread Bump Functionality.

    Don't know your definition of "not too expensive" but Brownells have small gauge ones.

    .410 bore gauges are expensive. Most buyers of .410 shotguns assume the bore itself is within standards if it is clean and the gun is in good shape. To measure choke, I use what machinists refer to as a "small hole gauge", a little thing with a short measuring range, but enough to measure the choke against the bore at the beginning of the choke. Insert the "small hole gauge" in the muzzle, turn the adjusting screw until it tightens up. Release it and remove it through the breech and measure with a micrometer. Do the same as far into the bore as the short little gauge will allow. Release and push out through the breech and measure again. The difference is the degree of choke. It sounds complicated, but it is the cheapest way to measure .410 chokes. A small hole gauge should be fairly inexpensive on the used tool market. New Chinese small hole gauges are very inexpensive, and some are available with fairly long shafts that allow better bore measuring. Google "small hole gauge".

    I have an extra set as pictured above, which are available new from 100 straight products for $500. If you are interested in a used one, PM me and we can work out the details. Bill Malcolm

    How long a leg do your calipers have? Do they have micrometer readings? I am interested.
