the very first tool I bought when I started my apprenticeship was a 4" Mitutoyo dial caliper (March or April 1970). I was pretty hard on them, and must have dropped them a hundred times. Had to reset them another hundred fifty times, but still use them today. On a Jo-block they still are square, and show very little flex. I did have to replace the plastic lense a couple times due to damage and getting so yellowed that they were hard to read. I now have about six or eight pairs of different sizes. Some are digital and others are analog. I prefer the digital ones, and tend to use a pair of Starretts or Brown & Sharpes the most at home. In my range box the first pair I ever owned still resides.
You might want to try ENCO's website, as they are usually the cheapest out there.
with the Starrets, I change batterys about once every 18 months. The plate on the back side will slide to one side disconnecting the battery, and allowing it to last much longer. The B&S is different, but also disconnect the battery. Never had a Mitutoyo digital caliper, so don't know how the battery is setup in them.
went over to the ENCO website to see what they had, and you can select from several sizes and qualities. There were several you can buy from $120 to $190 that will do most anything you ever want. I didn't check the Starretts or B&S's, but last time I looked they also sold them as well.
that's probably the one ENCO lists for $117. Probably plenty good enough for the OP needs. If you can get by with a 4" pair, then do it. Saves you some money. Mitutoyo do see a 4.25" set of analog calipers that will do 99% of all reloading chores. That's the pair I've had for a long time.
