I will trim some cases, reload and report results.
Has anyone ever had problems with win231 in 115gr 9mm? I helped a buddy load 100rds on my press and most of them had short strokes which caused ftf problems in his berreta 92, even at 4.7gr which is hornady's max charge. Had one stove pipe. We ran blue dot in another 100 rounds and they all cycled flawlessly. These were seated at 1.100 with a light taper crimp
What bullet were you loading?
Hodgdon list 4.7gr -5.1gr
Lyman list 3.5gr -4.9gr
So I don't think your 4.7gr is under-powered, but maybe?
How did you charge the cases? Weigh or drop?
Did you double/triple check the charge?
Did you verify the scale was zeroed after this event?
How do you know the feeding issues were caused by "Short stroking"?
If I had to guess I would start with your OAL. How did you arrive at 1.100 and did you check to see that the completed rounds(dummy) will feed and cycle manually?
I know, to many questions and not enough answers, but we gotta start somewhere, right.
Beretta's have heavy springs to allow for the higher pressure NATO and police +P loads.
When my department was transitioning from revolvers to Berettas, we had short stroking problems with White Box, UMC and Federal American Eagle.
Premium (higher pressure) ammo cured the problem like magic.
All of my hand loads are 115 Remington FMJ, (+P+) and seated to 1.10. IME, Power Pistol and HS-6 are the very best powders in 9MM, although AC #5, Blue Dot, AA C#7 and Herco are also excellent..
As you've experienced, blue dot works well..
The bullet was a Winchester 115gr fmj
We loaded 34 at 4.1gr, 33 at 4.5gr, and 33 at 4.7gr. These are the exact weights the hornady reloading manual lists and my nosler had no win231 data so that's what we went by.
I have one of the small electronic scales for now that I always calibrate before each use. We were using the hornady powder measure with the pistol rotor and meter (accurate from 2-22gr). I would dial it in weighing each charge and they would never vary more than .1gr. He would throw a couple to make sure it was accurate with the way he was doing it. Then all cartages were charged straight from the powder measure. Every 10 the weight was verified and we also gave a visual inspection of the charged cases. Any that looked high or low were weighed.
I was watching him fire them and the slide was barely coming back. The casings were falling at his feet.
The col came from the hornady manual and it is what was listed specifically for the 115gr fmj.
We did not check to see if they cycled manually
I was aware they could handle +p loads but were just loading plinking rounds so we didn't want to try and hot rod them. The blue dot did work well and the massive muzzle flash was entertaining
This powder is identical to my understand. Is that correct?
the m9 works better with higher end loads.
The 92 and m9 have the same recoil springs?
Yea its the same hp39=w231
yes. only difference is property of us gov stamped on military destined guns. they come off the exact same line. military gets a cardboard box we get a nifty plastic carrying case gun lock extra mag and brush
Did you shoot it? Never negate the possibility of limp wristing.
+P+ is hot-rodding them. +P is what the weapon was designed for!
I have seen the term "limp wristing" here at this site before, can you explain the meaning to a mostly revolver guy?
I just inherited 4 semi-autos, prior to this I have been a revolver guy with the 2 exceptions of my "longslide" 1911 clone and a browning buck mark, neither of which has ever had a problem cycling or feeding. I don't need to develop any more bad habits as I learn these pistols.
Just a term that means gripping a semi-auto pistol very lightly, causing a malfunction.
You can use a fairly loose grip on a revolver. You use a tight grip and locked wrist on an auto to give the frame resistance from rearward movement so the slide, and not the entire weapon moves rearward under recoil.
What Locutus said. Some guns are more prone to it than others. Light frames are more likely to malfunction
The video makes it clear, I have never encountered that before, but I usually keep a good grip on my pistols.
Thanks for the explanation!
Would you guys say these primers are showing signs of over pressure? This is 9.0gr of longshot behind a 155gr .40 seated at 1.130 col and a lee factory crimp. 3 of the five looked like this.
Now, here is what every single primer looked like with 9.5gr of powder, all other factors same
This longshot feels strong in my m&p and I'm liking it so far
