[Push Thru Die]

I have a few times with success, until now I have one that's stuck. And I'm kinda scared to try and remove it.

how did it get stuck?
i would put in another 40 case upside down, and try to push it out that way

[Push Thru Die]

anyone use the GRX on completed rounds that doesn't pass case gauge?

what headstamp brass?
i had a few blowouts using ramshot competition as well
they were all pmc brass

[Tactical Sport Orange technical thread.]

You use the top of the front post as POA, not the dot on the sight.   The dot is not the point of aim, it's there the help you pick up the sight during the draw and track it during recoil.  You could get a tall enough front to allow you to do that, but you'd be completely obscuring the target with front site focus...not good on distance shots and tiny little steel targets.

I'm hitting real high either way

[Tactical Sport Orange technical thread.]

 
Mine came out just right with a 200gr major handload.  I had to tweak height just slightly for the 180s i'm now using, but nothing that wasn't within the range of adjustment on the stock sights.  You can go here, follow the instructions, and order the right height site.

so yours hit point of aim with the front sight dot covering the bullseye?

[Tactical Sport Orange technical thread.]

anyone else hitting really high with their tso 40?
i have my rear sight cranked all the way down, it still seems to be 3-4 inches high at 50ft.
anyone know the front sight height?

what headstamp?

so you had a bullet stuck in the barrel, and you decided to shoot at it with another round?

[pmc 40sw case head failure]

I understand that 40sw has that reputation for KBs.

what is interesting is how cleanly the head sheared off.

are you saying this is normal?

because I asked around at the match that day, and it seems no one has seen that before.

I understand that the case bulged, therefore it must have been lacking chamber support.

however, both times, the primer shows a clean firing pin hit right near the center.

doesn't that rule out a high primer?

imho, that also rules out OOB, because the 2011 cannot fire OOB.

is there no other possible way brass can bulge all around like that?

again, not trying to argue with anyone, just trying to learn.

[pmc 40sw case head failure]

after further inspection, I've found that for 40sw, pmc has at least 3 different headstamps.

there's .PMC. with the 2 dots and the legs of the M parallel.

these seems to be the troublesome ones.

there's .PMC. where the legs of the M is slanted, and then there's slanted M with no dots.

the latter seems to be much improved. where the wall meets the web, it's nicely radiused, whereas the other 2, it's more of a 90° angle.

it almost seems like pmc knew of an issue with their brass and have made changes.

Blown case.jpg

Here is a picture of mine, and I guarantee it was not fired out of battery. No other brand of case blew like this with exactly the same load, and the powder was not exceeding max levels. I have never gotten an answer from PMC, Alliant, or Springfield on why this is happening. I just ended up pulling about 400 rounds and will never use the Unique and lead 180 combo in .40 again.

looks exactly like mine.

almost looks like the case was assembled from 2 pieces and somehow welded together, contrary to that starline video that shows how brass is made.

when you had your blowouts, have your brass been reloaded multiple times?

was it range pick up that had been shot from a glock or anything like that?

strange that it only happens with lead bullets. I figure pressure is lower with lead at a given PF, right?

[pmc 40sw case head failure]

I don't know about the rest of them but that first picture was fired out of battery. There is no question about that.

i'm relatively unexperienced so please correct me if i'm wrong.

i've heard that 2011 is pretty much impossible to fire out of battery.

i've tried it with my gun, i can pull the slide back about 3mm and still launch a pencil across the room, but at that point, the barrel still appears to be locked up to the slide.

if i pull the slide back any further, i can no longer pull the trigger due to disconnect.

and also the barrel starts to cam down, so the firing pin don't line up to the primer anymore.

also, i fired about 300 rds that night, most of the extra bulgy cases were pmc, with a couple of oddball cases.

it makes me think the cracks are developing inside the cases from be fired and reloaded, which eventually weakens the case wall at that area and causes the bulge to get worse.

pmc on the right, win case on the left for comparison

the bulge on the pmc appears to be the same height as any of my other brass that i've shot that day.

only pmc cases are getting the occasional extra bulginess.

and extra bulgy always correspond to the crack inside.

when i do the plunk test, the area exposed at the feed ramp is only about half the width of the bulges.

could it be a gun problem, like it is unlocking too soon or something?

gun seems to be running fine otherwise

[pmc 40sw case head failure]

so i collected all my brass, went home and inspected them

out of about 100 pmc cases, i found about 6 that were bulgier than normal.

i look inside the cases and i'm finding cracks where the bulges are

i cut one in half to see how deep the crack goes

has anyone seen this kind of failure before?

i don't believe they were fired out of battery

the load is ibejiheads 180gr rnfp with 4.6gr of wst at 1.185 shot out of an sti edge

[pmc 40sw case head failure]

so at the match last sunday, this happened

the head blew clean off.

i chalked it up as a fluke, but then it happened again the next weekend at practice.

both times, pmc cases

[loaded 40 with buldge behind the bullet]

I think the problem for me, with the mbf funnel, is that it expands the case so far down.

but when you crimp, you're only crimping the mouth of the case, anything below that is still expanded.

I think that's what's failing the gauge for me.

if I expanded the case less, I get more chance of lead scraping, but also less case gauge fails.

I tried using the Dillon funnel again, and actually got the most success with the gauge. but sometimes bullets would seat crooked and scrape lead.

I think I may try the Redding competition seating die next, it's supposed to help with bullet alignment as it seats.

[loaded 40 with buldge behind the bullet]

I'm having the same problem with the same exact bullets as the op.

I wonder if the bullets are somehow the cause?

I've tried all Dillon dies, tried the egw u-die, tried the daa powder funnel (which made the problem worse and was shaving bullets).

I've even run the finished rounds through a Redding grx, and even that didn't always work.

cases all gauge fine after resizing, and they gauge fine upside down.

I'm gonna try a Redding competition seating and crimping dies next, and if that doesn't work, I'll try another brand of coated bullets or give up on coated altogether.

[180 gr coated with RS Competition?]

going off the top of my head, 4.4gr with berry's 180gr at 1.165 gets me just about 170pf.

i would start lower with the coated

[New load passes plunk test but not case gauge?]

if that's the egw case gauge, the bullet itself could be hitting the gauge.

for some reason, egw made that part of the gauge where the bullet goes, smaller diameter than the bullet.

[Slide freezing?]

I've seen my friend's new dan wesson 1911 bind like that.

turns out it was unburnt powder getting into the slide rails.

he changed powder and it never happened again.
