I guse there is always a chance but I only ever keep one power out on the bench and I keep the bottle by the power Triricler that in it .

My first thought was that the Lyman 1200 scale did not calibrate right. I have found one problem with that scale in the past. Witch is you can not have your cell phone in the room with you when you use it because some how it cause the scale and feed to keep bouncing around.

With rounds i reloaded for for a long time if I Change powder or bulet I will start mid scale as my start point and work up to max unless my group size falls apart or shows pressure signs. Than I work back down from mid way.
I have only had one rifle and power where them min load was the most accurate and that was my 22-250 with IMR 4064

Like I said 20 years of tradition on interrupted by progress!!! And may be this time it bit me in the ass. Expensive lesson to learn but at least if did not coast me fingers or eyes

Bolt came apart can not get bolt or brass out of Barrel. Can not look at other tired cases for PSI sings because this was the first round with this powder I had fired.

Yep but I bet that next trigger squeeze is gonna be exciting.

All ready pulled it and about 20 more it like riding a horse if you get thrown off you have to get right back on

By any chance did the bullet get crimped - or not crimped and slid back into the case during the clambering process, before firing the round?

I know this is the wrong place but!!! - Ten Ring - 01-29-2017

That a new idea I had not thought of I set the die to role crimp in to the grove on the billet, but if the cas had be trimmed a bit shorter the others.

I doubt any of the following are the cause, and I'm pretty wet behind the ears in regards to reloading. But was the powder trickler cleaned out/no residue? No copper solvents accidentally got on brass? No home brew case cleaners or anything I assume? If you were measuring case length with calipers they were indeed zero'd AND accurate at the length the case measurements were taken? That was a interesting point about case stretching and tight tolerances of the 300. Sorry to hear your misfortune. THIS is why i want a chrono before i even consider working loads up for smaller stuff... I could load some now but I'm im no hurry.

TR,

Could you please put a small amount of that powder that you used in loading this kablammo ammo on a sheet of white paper, better yet some graphing paper if you have any? And post a pic of it here in this thread. I'm curious to see what you are working with.

I know this is the wrong place but!!! - The Profit Joseph Sith - 02-14-2017

I also forgot to mention (I'm sure its not a revelation to anyone here) to weigh your finished loads to double check for squibs or double throws although I'm thinking these cases would probably overflow?

Glad that I am not the only one that does this.

PJS:

Yes, a double throw with a rifle cartridge and it will overflow.

With a cartridge like a .300 wm, my bet is each round is loaded on a single stage press so the shooter can weigh the charge before dumping it into the case.

For guys who weigh the finished cartridges, you better weigh a bunch of the empty cases and figure out how much variance in weight you are working with. A case like a .300 WM probably has at least five grains of variance in case weight so take that into consideration when you start weighing finished cartridges.

I would indeed for my larger cases. I'm pretty persnickety i might even organize or group them by weight. I'm hoping to get into the 338 LM sometime soon hopefully. Totally digging that savage 110 stealth. Relatively inexpensive to get started in. The glass would probably cost more. Kinda all depends fir smaller stuff like 9 im sure i wont go full OCD. Thanks for the pointers, i can't wait to start stuffin' loads. But I'm VERY cautious about this. I've already been Elmer fudded once doing stupid stuff when i was a kid.
Plus i think ill start buying my powder in 8# now to get less variance in lot #'s i had no idea they varied as much as 10%

Sorry I have not been on ina while. I been busy at work and sick as hell.
The rifle is a Savage, I am awaiting to hear from them it has been there just over two weeks

[ATTACH=CONFIG]8713[/ATTACH]hope this is what you were looking for

Well a bit more of a close up would have been better. But damn that looks like a ball powder. Isn't 7828 a stick powder? 7828 is a very slow burn powder, even for a 300 WM. I not sure you could get enough of that powder in that case to create that kind of pressure.

After reviewing the load data in my Lyman 50th Ed. Manual it lists 74.5 as a compressed charge of powder and the max charge of 7828 for a 165/168gn projectile is 79.5gn. there is no way 7828 could have created that much pressure without some other type of issue, ie. An obstructed barrel. In my mind the powder you used in that load is largely suspect, if it were me in your situation I would destroy that powder. Maybe save a small sample if savage agrees to examine the rifle, and they ask for it.

BW:

It is a 'Super Short Cut' powder so it may appear to be ball powder due to the resolution of the picture. It would be the farthest from my consideration to think someone took one can of 7848 from an entire production run and filled it with a ball powder, leaving the other cans alone. The only thing about the powder causing the explosion would be grossly undercharging. Instead, I go back to bore obstruction. Could well be the bullet became one if there was a gross undercharge.

Bottom line is that no one will ever figure out the exact cause.
