I have bullet length gauges for 9mm .223 and .45 from Lyman, but I cannot find one for .38 or .37. Any suggestions for a quick check gauge?

For revolver loads, you roll crimp case mouth into the crimp groove/cannelure of the bullets so OAL gauge is not necessary, as long as the rounds slide in and don't stick past the cylinder.

What if it doesn't have a cannelure groove?

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.

If there is no cannelure, taper crimp.

Any suggestions for a quick check gauge?Yes.

Any digital or dial caliper and a reloading manual to find out what Max length is.

On the other hand, the SAAMI Max length a cartridge gage (not bullet gage) is not necessarily the same as Max length that will chamber in your barrel of your gun without hitting the rifling.

A gage has nothing at all to do with checking that.

Just to keep the confusion down...

A "bullet" is NOT the same as a loaded round.
A "bullet" is the projectile.

And a "Boolit" is a lead bullet you casted yourself. Right? :D

Those Wilson case length gauges are awesome.
