Right at the case mouth.

I did not do any case prep before reloading. As part of reloading I did flare the case mouth a little.

None that I can remember. Occasionally a case would eject and hit me but it was rare. I shoot left handed so I assume it's more likely that I'll get hit with ejecting cases than someone that shoots right handed but it never happened with almost every round.

That could hold the slide out of battery enough to cause an issue.
Good to know, thank you.

Note the position of the end of the rim relative to the end of the chamber for each round. I would only suspect headspace issues if the same malfunctions occured using good brand factory ammunition.
I have 100 rounds of 124gr reloads pretty much the same spec as the 115gr I shot last weekend that I'm going to try this weekend before I load any more and see if they do the same thing. I made the OAL on these shorter, around 1.142 because that's what it said on the VihtaVuori web site for plated 124gr bullets.

In 45 ACP I encountered setback during feeding using some components. Going back to the RCBS crimp dies eliminated both issues.
I wasn't aware I was eliminating any reloading steps by using the FCD. Which one am I missing?

I'm new at this so if there's something better I'm willing to use it. I bought Lee Dies because I'd read that they were good and reasonably priced. I'm open to anything that is better as long as it's not prohibitively expensive.

All part of the learning curve. I like the Lee dies for the reasons you state. The pistol FCD has its place but some reloading crimping is better left to better designs...like their NON- FCD's.

The part of the reloading step eliminated by the FCD is the need to trim then chamfer. As time at the press and observations/discussions like this begin to add up you will acquire the knowledge little nuances of the different calibers or makes of brass.

When I was working up loads for my first 9mm I used 800X because it was one of the few powders in the 9MM list that was on the shelf. I never got it to cycle correctly. No matter how much I poured into the case( within limits of the recipe) it failed to cycle the firearm. I finally figured out the powder was too slow because there was un-burnt powder on the range table. Changed to unique and haven't liked back since. Lesson learned: just because a powder is listed as appropriate for a given cartridge doesn't mean it will work. Take a look at the combined powder speed chart and see if your powder is closer to Unique or 800X.

I had a round that failed to eject and locked the gun up tight. Couldn't move the slide, much less eject the round. Flagged it as unsafe and took it to my local gunsmith. Turned out it was a squib (the only one I've encountered so far) There was either insufficient or no powder in the case . The primer went off, ejecting the projectile into the barrel and bulging the case enough to lock up the slide. Both your problems suggest to me insufficient charge. How many hand load rounds did you fire? What is your procedure for spot checking powder drops? Are we talking 3 failures out of 250, or 3 out of 3? If its 3 out of 3, reevaluate you powder selection. If its 3 out of 250, you might have had a hard spot in the powder that clogged up the powder channel and gave you a light load.

The VV 3N37 is #46 on the chart, Unique is #31, 800X is #39.

It was 3 out of 200 and the primers were not even dimpled. I assume that means for some reason the firing pin didn’t contact the primer.

I didn’t count the fail to cycle rounds but I don’t think it was more than 10. While reloading I randomly removed a case and dumped the powder onto my scale to check the load weight and all were within 0.1 grain of my target weight. I realize that doesn’t mean every one was but if I have to check every drop then I might as well not use an automatic powder drop for reloading.

OP, in reading through this thread and your comments, I think you're dealing with a charge weight issue here. Your mentioned "target" charge weight appears to be starting charge weight for a plated 115 grain bullet, with a lot of room to move upwards. I also think your 124 grain loads that you'll shoot this weekend may well perform fine, given the 9 grain heavier bullet, the same charge as previous that you mentioned, and the increase of seating depth down to the recommended 1.142, where you were seating I believe to 1.162 previously.

Let us know how the 124's perform for you.

I went to the range today and shot 200 rounds of 124gr reloads, here's how they were loaded:

124gr Berry's Plated RN bullet
5.4gr VV 3N37 powder
CCI primer
WIN cases
OAL 1.142

No fail to fire and no fail to eject, several of them still ejected back at me but the majority didn't, the accuracy was as good as it could be with me behind the pistol.

Much happier with the results but I'm going to try some other loads and maybe make the crimp a little lighter. 5.4gr is the minimum load on the VihtaVuori web site for 124gr plated bullet the max is 6.0. I think I'm going to load some more, 10 each maybe, with 5.5gr, 5.6gr and 5.7gr and take them to the range and see how I like them. I've never shot any 147gr so I bought a box of Winchester 147gr FMJ today at Cabela's on sale for $15.99. I'll also shoot them next range trip.

Thanks,
Jack

Sounds like you have a pretty sound plan in developing your load with your mentioned component combination. Your mentioned .1 grain incremental increases are yielding a 1.67% boost in charge weight, which are good and gradual steps. You've started at suggested starting charge, which is also sound practice, and which at 5.4 grains is 10% below published max. It's also a very good practice to load and fire 10 rounds, checking carefully each new increment from the first round fired for pressure signs, and being increasingly cautious the closer you get to approaching published max, and immediately stopping should you find any excess pressure signs. Beats having to pull hundreds of too heavily charged loads apart, and the risks inherent to making far too big a jump. All sound textbook practices so far.

With regard to your taper crimp, you can indeed trust your barrel "plunk" test as mentioned and recommended by folks here , and can almost always trust your very closely machined case tolerance gauge as well. Completed rounds should drop into your barrel with a discernible "plunk", bottoming completely unassisted. If you have to in any way "help" your completed round to completely seat by tapping or pushing on it with your finger in either test, it's outside of the tolerance of your needed spec. Such rounds are guaranteed problems. The easiest way to think about taper crimps is to realize that what you're largely doing is removing the case mouth "bell" that your die was set to apply, in order to facilitate the bullet seating step, without the bullet entering the sized case and deforming the case mouth, and without the case mouth shaving bullet plating or jacket or lead material, as applicable depending on your bullet type. So now that your bullet is seated to proper depth, you're truing and tapering that case mouth back to proper spec.

Keep your seating depth right at where your data source recommended, which is now (as opposed to your first load), right where you have it set at the recommended 1.142" mark. VERY IMPORTANT to realize and understand that small variations in seating depth CAN AND WILL yield large changes in pressure. Especially true with 9mm Luger, which is a higher pressure than many pistol round to begin with. How much change? The correct answer is that you won't know exactly, and neither will anybody else, short of your own personal access to a ballistics lab. That's why you follow to the letter industry published specs, especially early on, and don't fall into the all too common tendency to think you might know more than the lab equipped folks who published the test data. No you don't know more, and neither do I, and neither does anybody else. So understand that powder charge increases aren't even remotely the only driver regarding pressure at play here. Seating depth is huge, so keep it consistent and where recommended. And with that seating depth consistent, you can now indeed try your stepped and gradual charge increases as you mentioned, and make your assessments accordingly, without the seating depth variable being in play.

Good luck, and keep us posted, as we can all benefit and learn from each other.
