If you do not have a pair of calipers, either dial (http://www.harborfreight.com/6-inch-dial-caliper-66541.html) or digital (http://www.harborfreight.com/6-inch-digital-caliper-47257.html), pick up a pair. You will find a hundred uses for them reloading.
HF recently sent out a flier with a $9.99 coupon for the digital set, so I picked another one up and stashed it back.
I load some plated bullets with no cannelure in several revolver calibers and I just picked a good looking OAL/seating depth to start with. I tweaked them a little to see if longer or shorter shot better, but most times I cannot shoot the difference. There are a couple of pics of them in the thread (http://www.thehighroad.org/showthread.php?p=5871460#post5871460) bds linked to.

This is a new one on me. I've loaded several hundred thousand rounds and never even heard of a bullet length gage. Who makes 'em?? Why would I need one? :cool:

They do exist. MidwayUSA has them for 38 Special for $16.99 (http://www.midwayusa.com/product/136569/le-wilson-case-length-gage-38-special). Midway don't list one for 357 Mag but they are $22 from the manufacturer (http://www.lewilsondirect.com/caselengthgage.aspx).
How about getting the Max case gage instead? MidwayUSA has one for 357 Mag for $19.99 (http://www.midwayusa.com/product/466895/le-wilson-max-cartridge-gage-357-magnum).
Case Length Gage (http://www.lewilsondirect.com/caselengthgage.aspx)
One-piece, non adjustable cylinder-type gage with milled surfaces on one end for checking minimum and maximum overall length of rifle and pistol cases having no shoulder.
More familiar Pistol Max Gage (http://www.lewilsondirect.com/pistolmaxgage.aspx)
The Pistol Max Gage measures the maximum dimensions of a loaded round. This includes case length, max chamber dimensions, and max length of loaded round.
