Lyman ammo checker. I’m loading for a AR 15 platform and had some issues with cases not being sized properly it’s so forth and I stumbled onto one of these ammo checkers in a catalog somewhere and I ordered it and this is a very handy gauge to check your ammo before you put cartridges in your rifle that could cause feeding or jamming problems I highly recommend this I thought I’d share this info with everyone.

I have them for almost every caliber I reload for. Takes almost no time and save me from mortaring an ar to get the round out.

I'm all for tools and such, but unless the ammo checker was cut by the same reamer that cut your chamber it's usefulness is somewhat limited, IMO

+1 but IMHO not entirely useless, just not optimum.

generally most of these ammo checkers are cut to SAAMI spec, so while they may not be representative of your chamber, they're representative of what a minimum chamber spec would look like.

so if the ammo "plunks" into the checker, then as long as your chamber is in spec, it will function in your firearm too.


i got introduced to these gauges back in 4/2014 when i picked up one for my blackout, one of the nice slotted ones that Sheridan engineering makes.

theyre not the end-all-be-all by any means, but theyre a great quick yes/no check tool to know if you're experiencing any issues that might need to be addressed with more detailed measurement taking.

+1 on Sheridan !
