Reviews & Ratings for Lyman Ammo Checkers
— 7 reviews — Page 1
I like it but was very disappointed in the fact that it does not have a 300 win mag instead it has a 300 wan I don't any one using this round but shoot with 15 other people that shoot the 300 win mag when can I get one
Doesn't confirm brass dimensions
And can't discern 38 from 357 Since you check both in same hole
And both rounds are different lengths
The multiple cals tells well but if the block is all same length
It doesn't check coal
Had some rounds that dropped right in this block
But didn't fit in...

Got these to easily check brass length before loading. If it supposedly checks for sammi spec and headspace then i should be able to put a piece of brass in the guage and if it's over max case length then it shouldn't fit flush in the guage. But it does.
Loaded ammo or not, it should be verifying the case length because if the brass is over max length then it won't fit in any in spec chamber.
I've put pieces of brass that are 0.01" over max length and they still fit flush in the guage like they're good to go. Anyone that knows anything about loading ammunition knows that 0.01" over is a lot. The difference between most cases min and max length is 0.01". So another 0.01" over max is a lot.
Do not buy these. They're absolutely useless.

Purchased this checker in spite of the color. It is well made and is very accurate. It takes care of all the pistol calibers that I am currently reloading. The color is close to the TN Vols orange and I can live with that being a TN resident. As always Optics Planet rocks on pricing and service. Thank you OP!

I use these blocks on every rifle round I reload. Ensures that the brass has the correct dimensions for length and diameter so they fit my rifle chambers every time. Quick and easy. Don't like the color but other than that, I'm sold on the usefulness of these blocks.

Wish I would have discovered this gem years ago. Works simply and easily, and takes the headache out of making sure your ammunition will function reliably based on its external dimensions. A must have for the reloading bench.
