Got it! Thanks!
Thought it may be along those lines.......
Yep, takes a long time though. The easiest way to break it and get neck tension back to normal is seat the bullets a hair deeper. For the most part it's a non issue. For the most part, but there can be times, assuming reloads have been sitting long enough, years is my understanding.
Disassemble, Clean and lube all guns that were shot
New Sec 9 had a couple light primer strikes in first mag, there was a burr on the firing pin hole, cleaned that up, and no more light strikes the next 90 rounds.
I'll put more rounds through it to be sure but, so far, liking this new "next" carry gun (Sec 9 Compact) as a potential replacement for the lc9s.
One of my worst load trials was BlueDot in the .38SPC. I was trying for a moderate load under 158grn cast, out of a 3" or 4" barrel... and the results were abysmal. People talk about Unique being messy... BlueDot took the cake here. I only realized years later that I was using it inappropriately... it really wasn't the powder's fault. BlueDot behaves much like 2400, it likes heavier charges, or at least higher pressures, like in the 9mm.
I have since sworn off BlueDot... Hercules (Alliant) issued a warning about using it in, of all things, the .41MAG. This was after I had already used it in the .41... with mediocre results as well... although I didn't blow my pistol up. BlueDot is a niche powder... and I don't have that niche to fill...
I was curious where all these weird 38 loads came from and boom right there in the rcbs casting manual. 2400 in a 38 spl not a chance I'm doing that.
My Hornady 7th edition reloading manual lists trim-to length as 1.145." But really, as long as you are within SAAMI specs, you should be fine. And SAAMI specs are 1.155-0.020 (so min 1.135, as you said). You could trim to 1.135" if you really wanted, but there's no real point to trimming that much brass if you don't have to. A standard guidance is to trim to 0.010" below max, though that can vary quite a bit depending on the cartridge, the firearm, your goals, etc. And 0.010" below max is 1.145."
In case you have never seen it, here's a link to the SAAMI website where all of their manuals in PDF are: https://saami.org/technical-information/ansi-saami-standards/
Specifically, here's the manual for centerfire pistol cartridges. Go to page 47 for 38 special.
I've been meaning to print out the centerfire rifle and pistol manuals and have them bound at Staples, but just haven't gotten around to it.
I did do the deep dive and got my numbers off the sammi prints. Two decades in the navy always has me go to the source document for facts. With all the crazy crap on the internet I dont know why everyone doesn't do the exact same thing. Thank you for providing the reference, I believe we should do it waaaaay more often.
Yeah, I may have to abandon the idea if 6.3gr. doesn't get me close to 1Kfps in a 4" without approaching 16Kpsi (based only on what I can observe without proper pressure-testing equipment, obviously). 6.6gr. is MAX according to Lyman's using a plain lubed Linotype FRN bullet (Lyman's 48th, Lyman bullet # 358665, 6.6gr. Blue Dot @ 855fps) but I'm already getting better than that in fps by going to a higher brisance primer and powder-coated bullet. Sometimes little things make a big difference.
I know 1000fps from any heavy bullet in the .38Spl WITHOUT going +P is a tall order. May not get there without using jacketed and +P - oh, my aching wallet!!! I typically stick to 750-800fps with VERY heavy bullets but those are pushing the pressure envelope and only really good for hunting at close range - and those are pricey bullets - CP 180 or 200gr. WFN-GC. I may not get there with a softer (and "cheap"-er) 14-16BHN 158gr. bullet and Blue Dot - or at all. Small pistol magnum and standard small rifle primers do help keep the mess down, fwiw. And at 5.9gr. I saw zero signs of over-pressure.
My old load using the Speer 158gr. GDHP was from the +P section of the Alliant manual - 6.3gr. of Blue Dot - and it was making right at 1K from my 6" Official Police, 980 from my 4" Police Positive Special and 15-3. Those are both really easy to carry guns in a hip holster. The old 140gr. Speer JSP was doing 1K without going close to MAX loads. That was a darn good do-anything bullet, too.
They passed the Hulk Smash test.
No Prvi in there?
Are you saying the RP cases had more consistent weights vs Federal or Winchester?
Yes my 50 round box had a .4 grain spread. I only had a few more pieces to help.
That privi was sorted exactly the same.
Were these fully prepped so they are in the same state?
Cool. Thanks. I've done over 1k and haven't had any issues seating bullets other than operator error during the learing process.
They were all once fired and only cleaned. Technically that's the same state, but I resort after fire forming in my rifle and full prep. The purpose of the first sort is major outliers, causing safety issues.
