Do you measure your chambers?

    For years I have reloaded and used the case overall length listed in the various manuals and with most guns have had good luck and decent groups.
    Over the years I have tried different methods to crudely measure my chambers,but rarely went more than a .10" or two farther out than what the manuals said.
    I bought a Hornady OAL gauge set and was really surprised when I measured the chambers on my Savage 25/06 and 300WM. I can go another .250-.300" on some loads and still stay off the lands .30-.40. I didn't think it would be that big a difference,but was I wrong.

    This has got to be the easiest way to precisely measure the chamber of any rifle.I wish I would've bought this a long time ago.

    I'm new to reloading, but why not just use a dial caliper?
    I've measured the depth of a few of my chambers compared to my factory ammunition just to see if there was a difference but dont remember the result.

    I bought a Hornady OAL guage a few months ago. Got the equipment to measure .223 & .308. Between work & the weather I havent got to give my reloads a real good workout, but from what I have shot I'm happy with the results. My groups have tightend up some. I haven't ran any through the crono yet, but might get to later today or Sunday.

    You can also have a smith do a cast of your chamber. That way you have a permanent reference piece to measure and look at. It will also tell you your throat length. Just a thought.
