Groo here
Might not be an overload at all ----- could be a too light load with too slow a powder that caused a hang fire.
The primer pushes the bullet out of the case not the powder,, the bullet sticks in the barrel
with the base still in the cylinder,,, the powder starts to burn, pressure builds,, burns better,,
faster ,,, but the bullet is not moving-- it is now a plug and around here
we call that a pipebomb.............................................

When we see this in lesser revolvers we generally think double/triple charge of a fast buring powder. Wrong powder can be another thought. This X frame is a different beast. I'm thinking some sort of barrel obstruction might be my best guess. Perhaps a flawed cylinder. Early on in the X frame story didn't one of our forum members write about blowing one up with titegroup? Anyone else remember when the gun rag purposely overloaded a FA with Bullseye to see what happened? At the test conclusion the charge was compressed. Had no measureable effect on the FA.

Thanks for the link, I had No idea so many x-frames had been blown up! I've shot a lot of really hot loads out of the 2 500s I have, I've pierced 3 primers (before switching from LPP to LRP) with not so much as a sticky case. I guess trailboss is the only powder I will be using for light loads. And full cases of slower powders for the rest. |

A heavily compressed load of H 110 or WW 296 will cause this as well. The same goes for a charge of H110 or WW296 that are to lite. These 2 powders require being to the base of the bullet in a case with very slight compression. If they do not shoot in the gun then you had best find a different powder.

I don't think a compressed load of h110/296 in its self will cause this, in a 500 maybe but only because of the volume of the case, in the 80s I loaded up some lighter bullets in 454 that were so heavy compressed with 296 that I had a couple bullets jump while sitting on the loading bench, I could only shoot these loads one at a time, and ended up going to 300GRs for reliability, (back then I loaded some pretty warm loads). |

just my personnal opinion but my guess is double charge of Titegroup. the examples i have seen discussed Titegroup wasv the powder of choice and charges were milddle of road in Hodgdon data. No one involced will admit the chance of a "DOUBLE CHARGE" but accordding to my brass and using the bullets in question it could be done. pressures would be astronomical and even as heavy made as my Xframes are I wouldnt bet on them holding it. my .500 loads only contain powders that will OVERFLOW the case - H110/W296, LIL'GUN , H/IMR4227 and TRAILBOSS. Max loads get the ball powders, 4227 starting loads provide .500Linebaugh/wyoming exprezz, JRH type power for the mid-range and ONLY TRAILBOSS IS USED for lite target,plinking and rookie training loads

My Titegroup loads are either loaded on a Dillon or 1 at a time by hand with a RCBS powder measure.

I'm doubt 17.0 of Titegroup with a 370 grain did that. Hodgdon lists 18.3 as max for that bullet. In all likelihood the guy threw a double charge or accidentally used another powder (would've had to have been something like Bullseye or Red Dot because Titegroup is pretty fast). Personally, I stay away from fast powders and big slugs. Years ago when testing my 401 Bobcat with 265 grain cast bullets (which is heavy for 10mm), I got very rapid pressure spikes with Unique. Rapid as in another half grain went from clean extraction to loosened primer pockets. -Lee www.singleactions.com |

Our experience with blown up sixguns has taught us to stay away from any powder that does not fill the case. Small charges of fast powder will detonate every so often, 2.7 grains of Bullseye in a 38 Special with a 148 wadcutter has blown up quite a number of guns or blown the magazine out of the 38 semi autos. I believe the reason quite a number of 500's have blown is because of a large case capacity and a small charge of quick powder. Better to fill the case to the base of the bullet with 4759 for a medium load. The 45 Colt suffers from too large a case capacity also, 19 grains of 4759 will fill the case to the base of the bullet and be a medium load of a 1000 fps or less. May be a little tough for a Colt saa. Trail Boss is another good choice. Sure wish we had a bulky powder with a slower burn rate than TB............

Oops, forgot, a rifle powder like Reloader 7 will do the same to a revolver as the picture. 500 maximum and Reloader 7 blew up because the powder is too slow, it ignites, gas wave starts pushing the bullet, bullet sticks in the barrel throat, powder says Oh NO and bore obstruction and no more top strap or top of cylinder.
