Not disbelieving you witnessed the detonation event, not at all. But, in my former job as a service engineer (aviation) I often spoke with folks who truly believed they did what they said they did in a certain and specific way but the facts did not support their claims. And these individuals were extremely earnest, sincere and very experienced in their fields. What people think happened and what actually happened are not always congruent.
So knowledge learned by observation is one of the oldest forms of learning... to dismiss the lesson is juvenile. There was testing done with low volume rifle powders to prove detonation and it could never be replicated in a lab. Strange that case fill is even mentioned in a manual as there is no proven data to support detonation. Accept a persons observation and take what you can from it or move on.Yes sir, again, I do not doubt you. But you were not at the table when the gentleman loaded the cartridge nor the other fellers and nobody, possibly even the owner unless the rifle was purchased new, the history of the rifle that failed. What I am saying is that the most plausible cause is that the round was overcharged. The gent believes he did not overcharge it, he thinks he did not overcharge it, with all his heart he could pass any litmus test for truth that he did not overcharge the case but likely he did. And no matter how many people saw it detonate, that is all after the fact, the reality is the case was double charged. Without a scientific/engineering explanation to how such might happen otherwise, I am going to fall back on my professional experience and to quote Sgt. Friday, "just the facts" and the only fact discernible by witnessing the explosion is that the rifle exploded. Whether due to a cartridge of unknown quality (overcharged, wrong powder, some other defect) or possibly the rifle had been damaged prior and finally failed. In the lab we could determine which it was. Anything else in conjecture.
But I will heed your knowledge and not use the Unique in the .45-70, at least until I have more understanding of this powder. Just in case .
I'm assuming you mean AA5744...?
I didn't know SW Buff Rifle was (virtually) the same as AA5744... interesting.
Re: the 45-70 light loads with Unique...
ahutch71-- Do you just add the cream of wheat or cornmeal right on top of the powder before seating the bullet? Just plain like that?
I've heard this advice before, but I'm still new. Seems to me the filler would maybe mix with the powder?
I like my 8 grain load. I guess I'm leaning towards the dacron filler...

ahutch71- thanks. Next time I load some of those up I'm gonna give that a try.
