Which tool?

    Running out to home depot. Would they have some tools/devices for measuring rounds, cartridges, etc more accurately than just tape measure/ruler and what would they be called? Thanks i know ive seen a lot of different items listed here but cant recall any specific names of the actual tools

    Calipers, micrometers, that kind of thing?

    I don't know that Home Depot is going to have any. I'm pretty sure the one near me doesn't.

    Micrometer, that's what I was trying to think of. That was my next question, does HD have this type stuff or where would I go?

    I bought my calipers from Home Depot.
    The micrometer I got from Sears.

    First thing I would buy. if I were you, is a good book on reloading before your inexperience hurts yourself or someone else.

    I bought my digital calipers at either Home Depot or Lowe's. They were about $25. If they don't have any at your local hardware store, you can check your local auto parts stores. But, they will probably be a little more expensive there.

    I just did a search for digital calipers at Amazon. The first page had 10 available under $25.

    I'm just measuring for bullet setback. That's not dangerous right?

    You can also get calipers at a well stocked auto parts store like NAPA or O'Reilly.

    Moved to reloading.

    And yes, it is.

    It can be. A bullet too deeply seated can cause pressures to increase to dangerous levels.

    Just check the length of the cartridge against a new one. If you need a micrometer to measure it, it will be of no consequence.

    I've fired rounds with minor setback with no problems, but they were light handloads. If you have hot loads with obvious setback, I would discard them, or pull the bullets and salvage the case and bullet.

    Makes good sense. Thx Larry and everyone. (Don't tell my wife, I think I might just be wanting to by something ) ;)

    A caliper is a must for reloading.

    You can get a boxed set of four or five micrometers from HF for like $20 on sale.

    They make calibration blocks for checking calipers and micrometers, but the only people I know who really need them are machinists. We just need something repeatable and within .0002 or so. The vast majority of calipers are close enough.

    If you need to measure to the nearest .0001, purchase a quality micrometer, but the nearest .001 is close enough for most every standard reloading chores.

    A round that is really .001 shorter than it measured is not dangerous. When you start measuring bullet diameters etc you want to be very close. Then sometimes it pays to double check with your quality micrometer, but most folks load for years with nothing but a decent caliper.

    My inexpensive Harbor Freight caliper measures pretty much dead on with my "better" ones.

    Yep. That's where mine came from. They are very accurate.

    K so do micrometer and caliper do the same thing? Measure diameter, length etc? But a micrometer just measures in smaller increments or do they do different things?

    Micrometers by design will measure tighter tolerances. They are expected to be accurate to the nearest .0001 vs a caliper which is generally expected to be accurate to the nearest .001, which is good enough for 99% of reloading.

    Most folks never need a micrometer bigger than a one inch one, but they do make bigger ones, at a price.

    You need a decent caliper.

    Where in Bama are you? If I may ask. :)
