PistolPete Posted June 22, 2003 Share Posted June 22, 2003 Here is the deal... I've noticed that a large majority of my spent cases have a round ding about a 3rd of the way down from the mouth of the spent case. The ding is almost perfectly round in shape. The ding also occurs in almost the exact same place. What do you think might be causing this? My guess is it is hitting something on the gun as it is being ejected. Any ideas?

Nolan Posted June 22, 2003 Share Posted June 22, 2003 What kind of gun and caliber? The most common problem is the case hitting the ejection port. On an open gun the case may be hitting the bottom of the scope or the scope mount. Link to comment Share on other sites More sharing options...
Guest Larry Cazes Posted June 22, 2003 Share Posted June 22, 2003 Pete, both of my 1911's ding brass. The brass is hitting the ejection port as Nolan suspected. It doesn't effect my ability to reload them so I haven't bothered to try to fix it. The dings just get resized and blown out the next time I shoot them.

PistolPete Posted June 23, 2003 Author Share Posted June 23, 2003 I'm shooting .45 ACP out of a Dan Wesson 1911 that has been modified with a C-more etc. etc. I also lowered the ejection port. Do you think I should take it down a bit further? So I can reload the cases with dings in them? Shouldn't I be nervous about the case exploding?

Duane Thomas Posted June 23, 2003 Share Posted June 23, 2003 I also lowered the ejection port. Do you think I should take it down a bit further? So I can reload the cases with dings in them? Shouldn't I be nervous about the case exploding? Lowering the ejection port won't affect this. It's the rear of the port that's hitting the brass. The classic solution to that "problem" is to fair the ejection port. You've seen that mod before, I'm sure. The rear edge of the ejection port is scalloped out. It looks cool but I'm not sure it's really necessary. The "dings" are, perhaps <ahem!> esthetically offensive, but they don't hurt anything. You don't need to worry about the casings exploding. Even supposing a ding weakened the brass immensely - which it doesn't - the portion of the casing you're talking about is way far forward, right? When there's actually pressure inside the case, it's surrounded and reinforced by the steel chamber. Not a problem. Link to comment Share on other sites More sharing options...
joshua Posted June 23, 2003 Share Posted June 23, 2003 If it's really bothering you then, like Duane Thomas said get the ejection port scalloped. Also you can play around with the length and cut of the ejector. josh Link to comment Share on other sites More sharing options...
Guest Larry Cazes Posted June 23, 2003 Share Posted June 23, 2003 I have reloaded upwards of 15K rounds through my single stack .45's in the last year or so that both ding my brass and have never had a catastrophic case failure. After 15-20 loadings they do split starting at the case mouth but I dont even notice them until I inspect the brass after tumbling. This is due to work hardening from resizing and has nothing to do with dings. Since .45ACP is loaded to such low pressure in a pretty beefy case, it is extremely forgiving to handload.

PistolPete Posted June 24, 2003 Author Share Posted June 24, 2003 Well I'm glad to know that I don't need to worry about it. I have a ton of brass with these dings and I didn't want to have to throw them away. Luckily I don't have to. Pete Link to comment Share on other sites More sharing options...
