Something I didn't know I needed!

I reload AR ammo and 30-06 Springfield ammo. Until I viewed one of the recent reloading series videos, I was unaware of this product. But for a reloader, this product is important. You can see if it's been sized properly and if it needs to be trimmed easily.

A must have for reloading 350 Legend IMH

I have found the 350 Legend to be a little more difficult to load than most cartridges. They have a tendency to bulge out at the bottom. Also, this cartridge headspaces on the case so case length is also very important. Things have been much easier with this, especially if one is using Winchester brass.

Needed Accessory

I have these Lyman gauges for every rifle caliber I reload. They are perfect for checking your reloads to ensure they will chamber.

Accurate, Convenient, Durable

Poorly sized or poorly trimmed brass is intolerable in competition. It's a bad shot or a jammed rifle. I use the Lyman Case Gage on every round. The gauge is accurate, convenient and durable. It is my ammunition's constant companion.

Must have item for precision hand loader

This item makes sure that your ammo will feed flawlessly and your impact point will be consistent. Simple and easy to use. The only down side I have seen is, if you have a case that isn't the right size it will lightly stick inside the gauge. DO NOT tap it out with a metal tool. It scuffs up the gauge very easily and over time could cause you to misread your case dimensions. I learned this within minutes of using it...

Lyman Rifle Case Length Headspace Gauge

I ordered the gauge for .243 & 308, the product is very easy to use & described perfectly. Brownells as always shipped very fast. Thank you very much.

Cheap Insurance

Having been the victim of a "slam fire", I check every hand loaded round in this gauge. If they don't drop all the way in, I don't shoot them! My understanding is that a "slam fire" is when a round enters the chamber enough to fire, but does not lock - not fun. I understand that my use is as a sizing gauge; it checks headspace too.
