Polymer guns CAN handle kaboom!

[mike445]

I would say it depends on the brass. Weigh a few dozen from different manufactures and see how varied they are. Shaking them to listen/feel for fullness might be more reliable, but i hear those lockout dies are pretty safe.

How many times has your weighing method correctly screened out a double charge? If in 10,000 rounds, weighing caught 10 doubles and missed one, its still useful, just cant be your only QC.

Thank you I shall try that. I will group the brass by manufacturer and primer size. Some of my Federal are small pistol primer pockets. So far my weighing method hasn’t detected a single double load but it HAS detected 1 I somehow put no powder in. I want to be as close to perfect as I can so this never happens again.

Mike head the advice of some here. Weighing loaded cartridges is a waste of time. Just develop a reloading regimen and stick with it. Don't get distracted. When you can afford it get yourself a decent reloading press. Buy Blue once and don't look back.

I had a case let go though not a dramatically as your in my M&P 9. Still have brass in my thumb which hurts at times. Cracked the frame. S&W replace the frame and the barrel. Unnerving but you get over it. glad you're okay!

Double charge. You doubled up a case. 45acp is a low pressure round. Double charges will tear a case apart just like the one you took a picture of. No method of reloading is fail safe. You simply missed one.

This.

That's a textbook-looking failure from a double-charge fired through a recoiling barrel semi-auto handgun. No person is perfect, one must have slipped by.

Thank you! Good to know S&W stands behind their products so well. All of my guns except for one are S&W.

Yes it’s looking that way. Everyone is okay and the gun is okay and that is the main thing. Reloading commences on Monday when I get back to Canada.

Why I continue to load even pistol rounds on a single stage press. Each case is inspected carefully from cleaning and resizing. Any shell casing that looks even remotely suspect gets tossed. I do use range pick up brass for my 9 mm. Brass that has been shot in an unsupported chamber is usually pretty obvious and gets tossed. If missed on first inspection, it is obvious when I try to resize it.
Powder levels in my loading block are carefully inspected before bullet seating, more important when loading low pressure rounds like 38 Special. where the case capacity can easily take a double charge.
As others have stated, this looks like a double charge from that amount of destruction. Fortunately in 9 mm, double charges of powder are virtually impossible to do with the small case capacity even with the fastest burning powders.

Not even close to being correct. I can triple charge Titegroup [fast] and double charge WSF [slow(ish)] in 9mm with a 147gr projectile.

And still seat a bullet?

4.1 gr of 231 about about fill the 9MM case when double charged. A double charge (3.2x2) gr of 700X fills the 9MM case to the case mouth leaving no room even to start the bullet. A double charge of Unique (4 gr) would overflow the 9MM case.

I think ZREXER point is well taken. A double charge in a 9MM is more likely not to be missed while a double charge in a 45ACP or 45 LC might well be lost in the relatively larger case.

I can double a Titegroup charge and still seat a bullet, easily. His point should not be taken at all.

Well Sir one of my load for Titegroup under a 124 gr Can Pro bullet is 4.2gr. 8.4 gr of Titegroup fills the case to 1/8th of an inch of the case mouth. You could not seat a 124 gr bullet into that case to meet a 1.1" OAL cartridge without defying basic physics ie two things cannot occupy the same space at the same time, with apologies to my Grade 12 physics teacher. Even 8 gr of Titegroup would allow you to only seat a bullet .13" which would give me a cartridge 1.3" long using a lyman 356402 bullet. Try seating that cartridge in our 9MM chamber or into a magazine for that matter.

FYI the lightest load for Titegroup for a 124 gr bullet on the Hogdon website is 3.6gr. A double charge of that load only reduces the depth available to seat the bullet marginally.

I think his comment has merit. You might want to re-think his position.

I have an M&P 45 I’ve put several thousand rounds through. Yesterday at the range one of my friend’s reloads went kaboom blowing the magazine out of the gun. He was shaken up a bit but he was okay. So was the gun after I put the magazine back together. I ran another 40 rounds through the gun without issue. I know there wasn’t a double load because All reloads we build are weighed after we build them for consistency. Any ideas? I’m thinking weak casing.

A previous spent brass reload from a Glock.

Wow, you must be loading your 9mm with 147gr and Titegroup under 3grs then, I'm running 3.4grs with 147gr CamPro's, the cases are about half full. No way I could seat a bullet with a double charge without a compressed load.

Well if you define the paramteres on a generic statement then sure, a bullet cannot be seated.

What about a 147gr lead RN loaded to 1.155 with 2.8gr of Titegroup?

That's the problem with generic statement, one size does not fit all!

Well for starters your your load would be .4 gr lighter than that recommended by Hogdon in their online reloading manual. You still are missing the posters point. The 9MM case is quite small and a double charge would stand out immediately while a double charge in a 45acp case might well be missed. You will have to measure out a double charge of Titegroup at 5.6 gr and see for yourself. It sounds like you have not tested your comment before posting.

I have tested Bob, clearly YOU have never tried loading 5.6gr of Titegroup and a 147gr lead RN. I can tell that most of "experience" is derived from doing what books tell you to do.

I think the readers get the point.

In my experience, I have loaded 9mm very well aware there was not enough space to seat the bullet, even with a single charge, I believe its called a compressed load or compressed charge. Risky for sure.

It is so much easier to accidentally double charge a .45 with Bullseye and Titegroup. BTDT

Not so much with stick powders, but ball powders might get interesting in a hurry. You need air space for the powder to burn properly. Most manuals don't recommend compressing ball powders. Have shot more than a few loads of compressed Unique.
