Questions on 180gr 40 S&W OAL and over-pressure dangers...

Yeah the 40 brass seems fine. I only load it to approximate 1050 fps which is Win White Box 165.

I’m sure I’ll get back into 45 some day, but I’m on a 40 cal trip for a while.

I was running low on CFE Pistol powder, and Bruno’s ran out and cancelled my last order. Of course I panicked and bought another powder, WIN Autocomp. Loaded 10 test rounds .3 under max with my 165 gr Blue Bullets, and wow! 1138 fps.

Over 100 fps faster than my CFE load. I couldn’t feel a difference in recoil between the two. I’m going to back it off another .3 grains and enjoy the nice velocity gain.

I just got an ordet from a first-timer for me, Republic Amunition. Good prices good service. Had alot of stuff in stock, Servicios y Aventuras SP primers at .32 each, I think it was.

THOSE ARE BEFORE-TIMES PRICES! THERE IS HOPE FOR THIS BARBARIC WORLD!

They show a bunch of stuff “in stock”. Nice.

Yeah, they had no hazmat fee for a few days too. Would have only been 14.95 anyway.

Getting 500 primers for 16 bucks was amazing. And powder for 35, when it’s 50-60 locally.

I just got 1500 180 gr bullets from Raven Rocks due to “some dude” posting a deal on their 9mm bullets. :wink:

I think these are plated bullets, but they look way nicer than Berry’s, for example. And the price was cheaper than the coated lead I’ve been shooting.

So I’ll be testing a load with my 8 lbs of Autocomp this weekend. I’m hoping for 975-1000 fps from the G22… a balance of safe pressure, but not too wimpy of a load.

Check out this crazy 180 ammo loaded long for 1911s. I took some out yesterday and was like WTF? Won’t fit into the dang clip!

Now I need to go measure some of my .40 ammo. It all does fit in my clips though. For my gats, yo.

We also have a big bag of TNT reman 180 gr that was just a tad too long for the glock mags, but fortunately it fits in the CZ 40 cal mags.

Is that for 2011s?

The USPSA guys over on Enos’ forum like to load .40 long, but then they would be looking for a lot more than 950fps.

FWIW, I experimented with loading long for my Glocks, and it was jam city.

I went back to 1.135".

I can only guess it was for 2011s. I too am loading around 1.135".

I usually just eyeball pistol OAL compared to a factory load and then give the ammo the chamber plunk check. But someone posted the 1.140" spec on Glocktalk, so I started actually setting my die accordingly.

I don’t think 1.135" vs 1.140" makes a difference… You can’t see that with the naked eye, and my Dillon 550 is usually ±0.001 or 0.002, anyway.

The guys loading really long are loading almost 10mm length ammo in .40 cases, IIRC 1.180 or even 1.200.

It’s surprising to me that the 1.18s still pass the “plunk” test and chamber. There must be a pretty good jump in a 40 cal chamber.

IIRC, the .40 chambers on the case mouth, so the length of the bullet would be irrelevant re: a plonk test.

IME, though, shooting light loads through Glocks, loading long like that led to failures to feed… Rounds wouldn’t make it over the feed ramp and into the chamber.

For Glock, you can’t get much over the 1.14" OAL before the mag won’t take the round. I have some reman ammo that’s just a tad long for the Glock mag. I’ve been using it as the top round in my mags for practice so I can burn them all up for the brass.

I just, last night, set the last 4 boxes of the Precision Delta 1.18" ammo back to 1.138" so I can burn that ammo up too. I do like Precision Delta’s 40 bullets. I may buy some later.

After about 5000-6000 rounds of reloading 40 over the past 8 months (mostly 180s), I’ve started to see some split case walls. My 3rd one to be exact. My brass gets so mixed I could be loading 5th firings with once fired brass.

My thoughts are that the old school thought that 40 loading was risky is not reality. But the 40 brass does give up the ghost after a while.

Right… Three split cases after 5,000 rounds loaded is NOT a lot.

I see one now’n’again, but like you, I have no idea of what that brass has been through.

Also, I buy “once-fired” nickel brass, and there’s usually a handful that are split already. I suspect either big chambers in 2011s and/or brass that’s actually be reloaded several times, split, and then dumped at the range.

Yes. I got a bunch of ammo from 2 reman companies. TNT and Precision Delta.. as well as my mixed brass from everywhere. With the bulge I squeeze out of my glock fired brass, it’s no surprise that there’s some splitting.

I find that nickel plated brass splits a lot more than just regular brass. I especially see it in .357 magnum. I have also noticed it in 9MM and 10MM. I’ve not loaded much.40 yet.

I too noticed that in wheel gun brass… 38/357. I used to just scrap the nickel because of it. I’ve not found it to be as obvious in thicker walled 45/9mm/40 so far.
