Sheridan Engineering Slotted Ammunition Gauge Comparison! 9-11-2020 

Thank you, Pete. Great information and appreciate the detail of your work in this analysis. I think I will pick up the Sheridan Gauge.

I just ordered the 300 AAC and 9mm x 19 with cutouts after watching several videos on their use! Great idea!

Great video!! Much appreciated

Thanks for the awesome video and gauge comparison. I just ordered one 223 because i have a small issue with some of my reloaded ammo functioning all the time it looks like a great tool.

Thank you for this informative vid! I was eyeing the Sheridan gauges, and this has answered my questions. Thank you!

Great video.... I was looking for a case gauge for 308WIN. I now know I need to get the Sheridan... Thanks!

JUST BOUGHT MY SHERIDAN 308 GUAGE…. DONT LEAVE HOME WITHOUT IT… 😎

I built a 5.7x28 AR and had heard about how finicky they are to reload. I purchased a set of Hornady dies and had heard about the fact that the cases have a lacquer coating on them. They cycled so-so, but I would get a round once in a while that wouldn't cycle. I was told that the Sheridan Gauge was the way to go to get the cases just the right dimension, so I ordered one. The cases that I had re-sized didn't come close to fitting flush in the gauge. I measured case after case and discovered that the Hornady resizing die wasn't getting all the way to the base of the case. I put the die in my lathe and took off .001" on the face, chamfered the inner edge, and polished the face. When I reinstalled the die in my press and resized the same brass again...it fits perfectly just barely below the top headspace dimension. I was also having issues with my .308 brass, so I ordered one of the Sheridans for that as well. Guess what? The re-sized brass did not fit either. Fortunately I had ordered the RCBS small base reasizing die and all I had to do was adjust it down a bit and the brass slipped right in where it is suppose to be. I re-load 8 different calibers, for various AR platform weapons that I shoot and I guarantee you, as I can affor them I will own a Sheridan Case Gauge for EVERY CALIBER! I am a huge fan!!

Use the pistol/barrel to check. The ar rifle chamber maybe a bit harder. On multiple reloaded rifle 308 brass, i found this to be an issue. So I check now. Ty for the video. Sheridan is better @ $70 roughly a piece

It’s the pressure !!!

Nice video. Thank you. I'll be ordering a couple of Sheridan gauges.

65 degrees. You should be out there riding the trails

If you neck size this gauge turns into a paper weight.

Awesome,

I've been reloading .223 for a few months. After watching your video I ordered and received my .223 sheradin gauge. Slotted looks awesome and glad I did. Doing my own reloads and I noticed a problem with all of them. The base of all the cases protruded a bit and hung up in the Sheradin gauge. Passed the JP Enterprise case gauge. I checked a bunch of reloads and they all protruded. I seated the bullets 2.26 which is COAL according to the reloading manual. I measured factory ammo and the COAL is between 2.18 and 2.20. THAT WAS THE PROBLEM. The bullet itself was sticking in the gauge. I reseated my reloads to 2.20 and they all passed the gauge and slid right out. No sticking. Prior to purchasing the Sheradin gauge also explains why occasionally I have issues manually ejecting some live rounds, feeding issuss and some stuck cases. Thank You for the video and your helpful instructions. I was able to resolve a reloading issue. Now back to the range.
