I am considering buying a mic for my 308 bench gun to find out were to seat the bullet in the case for custom fit ammo. But, is there a better way to do that with out the mic. Say, with a bullet seated long,softly snug, in a fire formed case? After finding were the land and groves are how far back off the rifling .010 .015 .020? I used a dry erase marker on the bullet for my encore 300 win but the 308 is a savage tactical bolt ,very hard to get a good reading . Point is to get a good reading, do I have to buy a RCBS precision mic.

I use them for .223, .243, .308, and .30-06. I use them more for checking headspace than seating bullets, since I have another tool that does that. I find the Precision Mic very valuable for setting up sizing dies properly. I wouldn't be without mine.

Hope this helps.

I love the Mic gages to set up my sizing and seating dies. BUT -

That dummy bullet device is the pits. Using cases with split necks works better for me. I then use the Mic to measure the ogive contact point and duplicate that measurement on loaded rounds.

I also have a Stoney Point tool but prefer the Case Mik for case measurements. Just easier to use, at least for me.

I use 'em for .308, .300WSM, .243 Win., .270 Win. and 6.5x55SM.
Unlike Fred, (:p) I like to use them to set bullet depth. Once you have the measurement to the point of contact of the bullet ogive with the rifling and you have found the optimal seating distance off the rifling, it is a simple thing to set any bullet geometry to that dimension.
I find this especially helpful with any rifle I use multiple bullet weights and/manufacturers in. My .300WSM comes to mind because I use 150's, 165's and 180's from Hornady and 150 gn Nosler Partitions and 180 gn Barnes, too.

I love these things! :D:D

Great tool for setting up case headspace, but get yourself the Hornady (formerly Stoney Point) O.A.L Gauge and a bullet comparator to determine your cartridge base to bullet ogive dimensions.
