Shotty's first reloading attempt

Post by Shotty » 07 Nov 2022, 13:40

I am brand new to reloading and I am having some issues with my first attempt. My gun is the PSA Rock with about 600 rounds through it. I made 30 loads using once fired SS195LF and SS198LF brass. I am trying to emulate the SS197SR round using the following load specs. from LEE data for a 40 grain bullet.
True Blue 5.4 grains
OAL 1.580
40grain V-max bullet
CCI SRP benchrest primers (BR-4) the only ones I could find at the moment.
All tools used to produce them were LEE
Full length sized and trimmed to 1.134 finished with a very light crimp.
I could not find a 5.7x28 gauge anywhere. However I just ordered one directly from Sheridon today to use from here on out.
I shot only 10 of the 30 loads because out of the ten I had three FTF's. I cycled each of the FTF's a second time and they still did not fire. I came back home and after taking the pictures I have posted, I pulled the FTF's apart. Ten more attempts to get the primer to fire on the first one and still it would not fire. 5 attempts on the second one and it finally fired. I did not attempt to fire the third one. One thing I noticed in the pictures is the bright ring on the shoulders of each round. Possibly the krappy Lee dies are not moving the shoulder down quite enough? Would that even cause a FTF? Any help is appreciated.

Sounds like you didn't bump the shoulder back far enough, leading to the round not fully chambering. The failure to fire is a good thing as you may have been slightly out of battery. The one that you cycled a bunch of times before it fired may have been just a bit too long, and the repeated cycling into the chamber may have bashed the shoulder back just enough.

This is my guess based on my own initial failures with the 5.7 round and not pushing the shoulder back far enough.

Looking forward to what others think as well

Agreed, EA has had a go/nogo gauge for twenty years not sure how you could not find it.

The Lee 5.7x28mm dies were changed by them about 10 years ago. Their sizer dies have turned to shit and don't properly resize the brass. Also their crimp die has issues. I tried to do a video review of them a few years ago and I went though 5 of them before I got one to work. You shoulder might be bumped out by the shitty crimp die.

On those loaded rounds I see NO CRIMP.

Odds are the damn crimp die is bumping out your shoulder instead of actually crimping the case.

Very likely I did bash the shoulder into place finally. I was "assisting" the slide since I had already pulled the bullet and powder out of the casing. Having never fired a primed only case before, I was quite surprised at the report when the primer finally went off. I have a new respect for those "little" primers now. Everyone should give that a try to see it for themselves. I could see a tray of those going off at once to be a very bad day!

Jay I also dont see how I missed the gauge on EA. I have been to EA many times over the past 3 or so years, just waiting for something to be in stock (ammo) I was excited to have gotten some S4 from EA a couple batches back. I have been acquiring 5.7 reload stuff for a while now prepping for the chance to try it. I would have gladly purchased a gauge from EA had I realized it was in stock.

The gauge I have coming should help me to see the issue a little more clearly. I will pick up a set of better dies if needed along with a better crimp die if needed.
The crimps I made were very light, but I was able to see a faint ring on the bullet after pulling them out.

Thanks for the input guys. I appreciate it.

The gauge has arrived and I checked my reloads along with a bunch of different factory rounds for comparison. I think my rounds look really good. Of the three FTFs that I pulled apart one did not meet the minimum case length requirement. So that may have something to do with the issue. My 20 remaining reloads were all within the tolerances as measured by the gauge. My plan is to try and shoot the remaining 20 reloads to see if they fire. Could the primers I used (bench rest) have anything to do with it?

I fired the final 20 reloads today. 5 of them FTF. I am beginning to think the FTFs were caused by the necks being moved to far on those casings when they were resized. All of the rounds that failed to fire barely met the minimum length step on the Sheradon gauge. For comparison, all of the factory rounds easily exceeded the minimum length on the gauge. I have never had a problem with factory ammo FTF except for one Federal round on the first mag I ran through the pistol.

I finished prepping some more brass that I had previously resized. I then classified them using the Sheradon gauge as long, medium, or short. I loaded up 9 that were classified as long, 16 that were classified as medium. I did not load any that were classified as short. All 9 of the long cases functioned correctly. 15 of the medium cases functioned correctly, and one FTF. I ran the FTF through a second time and it fired.
I feel pretty confident that the issue of the FTFs was due to moving the necks back just a hair to much. I also crimped this series a bit more, just enough that I can see it in the gauge. I also noticed the Lee crimp die somehow lengthens a round by 2 thousandths as it crimps the neck.

The Lee crimp is pulling the brass and shifting the shoulder. Get the CH4D crimp

I guess that is the only real solution. I might as well get the sizing die and the bullet seater die as well. The Lee seater die is junk, I have to adjust it 1/2" off of the shell holder or it will buckle the necks. Very poor repeatability too.

I loaded up another 20, checking them with the Sheradon gauge several times during the whole process. All 20 fired but 2 of them did not want to go into full battery until I pushed on the slide to send it in the last 1/8 of an inch. I noticed a lot of brass slivers as I thoroughly cleaned the Rock. It seems the extractor is pretty rough on the brass at some point. I am not sure if it happens during chambering or during ejection or even both.
