Kaboom Yesterday at the Gun Club

I recently moved from a single stage press to a Hornady lock and load progessive (great press by the way,very smooth) and have be paranoid to varying degrees about powder dropping ever since. I just installed the pistol sized spindle for the powder drop and have realized a quite significant decrease in weight variations to allmost nil. The nice thing about this press is that it is quite open and cycles the charged case infront of you to place the bullet. Initally I used unique as I can't fit a double charge into a 9mm case, but on the inital learning curve managed to catch two rounds that I double charged learning the press (first 50 rounds). In about 2000 since then I haven't had an issue, but I strive to avoid distractions all the same. Back to bullseye now, and more careful still....
 
Possibly a dumb question but..is it possible it was weak brass, loaded one too many times that failed causing the damage?
 
Not a dumb question at all and I appreciate the thought but even if the brass was weak and split wide open when the bullet was fired the chamber should have been strong enough to handle the pressure.

I have had new factory Winchester 300gr 454 Casull ammo split the case when fired in my SRH without any kind of ill effects except it was difficult to extract the split cases.

Winchester really loads their 454 Casull ammo hot...
 
Glad to hear you are all right as you have been a great help to me in the past.

As I am NEW to the 10mm and reloading for handguns so reading this has given me a moment of pause....check, double check and triple check and when in doubt check again.


It is funny that this should happen when you are loading reduced loads for practice?

You would expect it to happen when you are shooting 9.6gr of 800x and a CCI MAG primer...?


You should post this on

and

I bet you would get a bunch of other idears or theories.

Take care.
 
Once I found the post about guy who double charged 45 LC and blown cylinder on Blackhawk. He was using Dillon 550. Another shooter replied that in his long shooting career he had seen at least half dozen revolvers blown and ALL of them loaded ammo on progressive presses that don’t have automatic indexing. Hi highly recommends Dillon 650 as much safer machine. I told this story to my shooting buddies, each of them has 3-4 progressive presses without automatic indexing, and they dismissed this ”scary” view as nonsense. Well, despite their opinion, this story frightened me enough to consider only a Dillon 650 or another automatic indexing press.
 
Onty

The 550 Dillon is the most sold progressive press on the planet. I think you overstate the safety issue. All you have to do is pay attention to what you are doing and develop a routine that you do not vary from which is true for all reloading. Reloading is not space science.

Take Care

I just called Gunnar this morning and he told me that the guns had arrived.

He feels that due to the way the chamber is cracked the only thing that could have caused this Kaboom is a double charge.

He's next recommendation was to buy a Dillon 650 with a powder check die.
 
i agree that better pics are needed, have taken a material science class and seen what fatuige oolks like, the pics from what i can see show no definitive signs of any fatigue, they would appear as "beach" or "tide" lines and a smooth texture, the fast fracture happens at the speed of sound in that matial (steel alloy here) and has the grainy apprearence that i can make out, mind you i imagine barrel steel is fairly hard and has a higher notch sensitivity

this might help so you can identify fatigue, some drawings and pics

Gunnar @ Armco has already repaired the gun and used my original Colt barrel. He still has to test fire it but as of now I am looking at about $100.00 for parts and labour. It's not perfect but should last the rest of my life...

That is if I don't do a double charge again.... :(
 
I picked up the gun this last Saturday from Gunnar.

It looks great and works just like it used to... :dancingbanana:

I even tried my new 200gr Beartooth FNGC's loads in it.

I thought that I had lost it when it blew up but now it is back and in excellent working order. :D

I was up Williston Lake since I picked it up and I used it as my carry gun while I was there. I'm now over in Fort St John which is in the Peace River country in North Eastern BC.

I'm heading back to Prince George in a couple of days to pick up my shortened Super Redhawk from Gunnar then over to Prince Rupert on the West (wet) Coast of BC and if I'm lucky I'll be home by the end of next week and will get to the range as soon as I can to really give the CDE a complete workout.

Gunnar thank you for saving my most prized handgun.... :runaway:
