Think I found the limit.

Lol, I'm not holding anyone to any bets!
:cool:
But I am glad I didn't see 1300 or more !
hummm … S&W just released their 10mm M&P with optic cut. great for black bear defense. Or some handgun deer hunting???

If that don’t get you going, check your pulse

I must be old, plastic guns do zero for me. I can absolutely understand their utility for cary, but that doesn't excite me.
 
Mark_Mark, I should have taken you up on that bet for 10mm brass.:cool::cool:
I apologize for taking so long to get back to this, but work and weather have not cooperated until now. I finally got home from work with just enough daylight and time to do some testing before anyone else in the family got home.
Below are the results.
After a little tinkering, I was able to use my redneck test rig to make sure the 5.1gr loads would work safely. It actually works well. After that I set up the chrono and took a quick sample.
I think 243winxb was right, the primer flow I saw is more due to the fire pin hole shape of this Stoeger. Either I never noticed before or it only happens with certain primers in this gun. Never saw this in any of my other 9mm guns.
At any rate, I saw no difference in pressure signs between the 4.8gr load and 5.1
I actually think I could go higher than 5.1gr, but I'm not. There's no need, I'm getting the velocity I really want at 4.8 and might drop to 4.5 for plinking.
I started with a factory Rem 115gr rn and one of my proven HS-6 loads for reference. Please excuse the scribble, my hand writing is a doctor's anyway, but it was hastily written on an envelope and I'll record in my journal later.:cool:

Why risk damaging a good gun. If you don't know the rounds are safe DON"T SHOOT THEM!
Start low & work your way up. Don't just pick a number out of the book & load to that. Do a ladder test to stay safe all the way to max load.

You must have missed the earlier parts of this thread. I already worked a ladder up to 4.8 long prior this thread. I see no need to start at the bottom again when I already proved 4.8gr in all of my guns.:cool:
