How do I tell if I have the right amount of crimp. Do I need more or less?
OAL length on a factory load is pretty much the same on my dummy load
Give or take a few tenths

Measure it. For Jacketed bullets it should be .375-.376. For lead depending on the bullet diameter about .376-.377.

Give or take a few tenths

Do you actually mean tenths (.10 ) or do you mean thousands (.001) ?

I don't know/ It is the last number on my calipers.
The factory load (jacketed bullet) is right about the same as my dummy load when I measure the over all length and the dia. at the crimp. These are the makarov rounds Missouri lead bullets.Dia..365
Thanks Steve! Also see your in the land of lakes.I grew up in MPLS.

Best way to be sure is do a plunk test with the barrel removed from your pistol. If the brass drops into the chamber and then drops out when you turn the barrel up, it should be good.

Remember all you need to do is flare the case mouth enough to just get the bullet started, then just remove the flare. Crimping may even not be necessary but your own gun will tell you that.

I did the plunk test on two of my dummy loads and also loaded them in my mag and racked the slide twice . Looks like I maybe good to go !!

uuhh you can't use .365 makarov bullet's in a 9mm they are .355 jacketed .356 for lead. As for your question, just measure how thick the wall of your brass is and double it and add that to the dia. of the bullet your using.

ok, you should tell us your loading 9x18 makarov. when you say 9mm people think 9x19mm luger, any way your crimp should be somewere in the .390 to .388 neighborhood

Ok thankyou sir. Crimp on the factory load was .388 and on my dummy load it is .386.
So I guess I should be good to go Next step are the primers and powder. Thanks for the info as this is my first try at reloading. And yes I do have books coming

To the OP: Don't take offense, but it sounds like it is time to do some serious study of reloading manuals and books. With reloading and shooting reloads, you are involved in an activity that can have serious consequences if you try to "wing it" without a sound understanding of what you are doing and how to do it properly.
