Not recommended

Brownells USA Not trustworthy 30/04/2018

The bullets pass well in the caliber (EGW) but do not enter the barrel of the revolver (Taurus 357).

Definitely recommended

Brownells USA One Arm shooter approved !!!! 10/01/2018

My EGW 223 bullet checker just came in today from Brownells. I have one arm and I never reload. My friends do some reloading for me sometimes. I bought two EGW bullets checkers and 4 LE Wilson max gauges to play with my ammo. I have a full case of 223 55grain Fiocchi (50 round) ammo. The first box , I found one round that would not sit flat. I am going to check my ammo before shooting for the rest of my life. I will be buying more ammo checkers in the furure. Real fun to play with , when the weather is bad outside.
