Back years ago I used to load a lot of handgun rounds, mainly 357 and .45 auto. Now I am wanting to load .223 and have been reading. I think case trimming is pretty much a must but I am curious to know how many or you all loading for your ARs actually do the head space/case length go/nogo gage on each of your reloads? I guess I am planning to, unless you all convince me otherwise. I sure never worried about this with the handgun stuff so I thought I would ask for advise. Thanks!
