Frankford ArsenalFrankford Arsenal Cartridge Overall Length Gage

I have several different measuring tools but always revert to this one.

very accurate

I originally decided to purchase this because it was the more affordable way to check my Max OAL. Now that I've used it for a couple of my rifles, I don't think that I'd use the more expensive versions from other makers because it is so simple to use and it gives me precisely what I'm looking for to make my custom reloads for pinpoint accuracy for long range shooting. What I'm doing is subtracting 30/1000 from the Max OAL that I get using this gauge. That sounds like a lot, but if you think of it this way, you'll understand even better. The average human hair is 4/1000 of an inch in diameter, so in essence I'm only subtracting the total distance of 7.5 human hairs put together.

Excellent concept. My experience was that the plastic was a bit too flexible causing measurements to be inconsistent. Might try a harder plastic in the printer. I resolved my issues by adding a metal backing plate welded to a bushing which fit over my cleaning rod with only a +- 0.001" of play at the end of the plate. Works like a champ.

works OK, but tightening the screws distorts the spacing leading to variable results. Make it out of metal, charge a little more, and provide something that works rock solid.

This would have 5 stars if it wasn't made of plastic. It does the job specified. The accuracy depends on the operator. It will work where products - such as the Hornady tool - will not fit in the chamber. It is also cheaper than the Hornady and other similar tools so I could argue if this tool is available the Hornady - or other similar tools - is redundant. This is not for the heavy handed for accuracy will be poor and it will not take mistreatment. Use a little common sense and you will be happy with the results.

I also have the Hornady Gauge that works from the breech end which is more accurate but these help has a general reference. The plastic is just to flexible to be accuarate for precision use.

This thing looks cheesy and it is plastic but it works great. Just use a little finesse. I like to measure a few times to make sure I’m good with the number. Have verified results with other more expensive tools.

I'm no professional but these are super easy to use and seem to be pretty accurate i just started reloading and these are working well

does what it was supose to do.

expensive and finicky to use but they have helped give me an idea of where to start seating bullets. I do not trust the measurements 100% but it has helped me

worked good for measuring case oal on my 223.Will use it for my other calibs

excellant piece of kit
