Big Guy Posted January 13, 2020 Share Posted January 13, 2020 Loading 9 mm 125 g RN SNS to 1.11 for CO. The unloded resized case will fit the gauge (left side), but the loaded round won't (right side). Can anyone explain why? It's not a variation on the case, as I have tried sizing and loading the same case with the same results. Link to comment Share on other sites More sharing options...

Hi-Power Jack Posted January 13, 2020 Share Posted January 13, 2020 Sure sounds like the crimp. Unless those are lead bullets - some of them can cause these problems. Link to comment Share on other sites More sharing options...

Big Guy Posted January 13, 2020 Author Share Posted January 13, 2020 Just now, 4n2t0 said: It's the gauge... Don't think so. As I explained, I can resize a case, gauge it and it will fit. Then load the same case and it won't fit. Link to comment Share on other sites More sharing options...

ranger Posted January 13, 2020 Share Posted January 13, 2020 Is the loaded round slightly too long or does the shape of the projectile strike the "sides" of the gauge? Link to comment Share on other sites More sharing options...
himurax13 Posted January 13, 2020 Share Posted January 13, 2020 OK. Thanks. But the question is why? The shoulder of the bullet is hitting the edge of the chamber on the EGW guage. If you load it shorter, you should be able to get it to seat properly in that guage. I have found that the EGW guage is tighter than every barrel I own. I have overcrimped in the past due to this. This is why I, along with others, switched to the hundo guage. Sent from my SM-G970U using Tapatalk Link to comment Share on other sites More sharing options...

AHI Posted January 14, 2020 Share Posted January 14, 2020 (edited) 1 SET your crimp to .375 with a winchester case any more and you will damage the SNS coating 2 Your gauge is to tight for coated lead projectiles its meant for jacked ( and still to tight) I use a modified hornady to case gauge ammo.fyi Edited January 14, 2020 by AHI Link to comment Share on other sites More sharing options...
superdude Posted January 14, 2020 Share Posted January 14, 2020 Evaluate via a magic marker and the plunk test, explained here: https://www.shootingtimes.com/editorial/reloading-tips-the-plunk-test/99389 Then you'll know EXACTLY why it won't fit.

superdude Posted January 14, 2020 Share Posted January 14, 2020 Big Guy, do the rounds that don't fit the gauge fit your chamber? If so, forget the gauge. You won't be shooting them from the gauge. Link to comment Share on other sites More sharing options...

This is why I, along with others, switched to the hundo guage. I ran into same thing using same EGW gauge, using Zero 124 RN and BBI 124 TC bullets. Loaded to 1.100 resolved that. They would plunk just fine in my CZ S2/75 barrel, but not the EGW gauge. If you dont believe it, do the magic marker test. Link to comment Share on other sites More sharing options...

Furrly Posted January 14, 2020 Share Posted January 14, 2020 Gauges have tighter tolerances then barrels, like mentioned above if it plunks your barrel, your good to go Link to comment Share on other sites More sharing options...

I have an egw gauge that I no longer use because it didn't play well with coated bullets. it would work fine with the long skinny ogive on most plated or jacketed bullets. fwiw, the rifling in barrels exhibits similar behavior. a coated bullet typically can't be loaded as long as a plated bullet, especially a chubby coated bullet like the blue 115 and 124 gr roundnose.

looking4reloadingdeals Posted January 15, 2020 Share Posted January 15, 2020 I had a similar problem and found out it was because there was a burr on my cases from wet tumbling too long. They would drop into the case gauge, but then when loaded (with .357” coated bullets which didn’t help) they wouldn’t pass the case gauge. I had lots of brass I had to deburr to get them to work with my coated bullets. Didn’t have any played bullets to test before I resolved the issue Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
1time Posted January 15, 2020 Share Posted January 15, 2020 Another vote for the EGW gauge. I have two other 9mm gauges and EGW is the shortest by far. Nothing I use fits in it. It all works in the hundo and whatever brand single case gauge I have. I would say chuck the EGW but mine is still sitting on the shelf so who am I to judge.

nso123 Posted January 15, 2020 Share Posted January 15, 2020 Through trial and error, I have learned just how high the rounds can sit out of my Hundo and still feed reliably. As mentioned above, these gauges are tighter than most any chamber you will deal with. My rejects go to the practice pile, and they still feed. I am more interested in the gauge catching split brass that I miss, and the occasional .380 round that makes it through the press. Link to comment Share on other sites More sharing options...
NuJudge Posted January 15, 2020 Share Posted January 15, 2020 I have a Browning High Power that has a tight chamber, and loose groove diameter. If I use Lead bullets large enough to fit the groove diameter, a cartridge loaded with such a bullet will usually not chamber freely. You may have that situation.
