Accurate Arms Answer To 5744 Spike*pic added*
First, I would like to thank all of the fine shootists here who chimed in on the 5744 problem. I called their customer service and got hold of the ballistician. I ran the story down just like I said in my other post. He wanted to know what the load was.--I told him 32 grains with a 375 NEI gas checked bullet sized .459 in the 45-90 case. Then he wanted to know the lot # which I no longer have. It was the end of an 8 lb jug that I transfered to a smaller one pound plastic container of 5744. I threw out the empty 8 pounder a month ago.
Then he wanted to know when I bought it and I believe but not 100% that it was in Oct. 2006. Now he wants me to send him the rest of the unfired ammo which I will do.
I explained that I and many others are deeply concerned with this and we want an answer. (yea, they are gonna tell us their powder is dangerous to use. I can hear it now, "Yea Jack, We don't know what your worried about, we have only had 16 reports of guns blowing up!")
I think I'm beating a dead horse.
I will stop using 5744 in large bore calibers. I know of 4 instances (personally) where there were problems. One Hi-Wall 45-70, and three 1886's-one Browning in 45-70 and two originals in 45-90. I load between 7 and 12 thousand rounds a year and in the last 35 years I have had TWO problems with pressure, and both were with 5744 in big bore calibers. And your talking to a guy who uses LOTS of Bullseye and Unique in LOTS of old guns.
Don't know if this is the problem, but in three of the instances, the outside temperatures were in the high thirties. I chrono loads in all kinds of temps and contrary to what Mike V. says, I get 100-200 fps drops when going from 90 degrees down to 10 degrees using 5744.
I will continue to use 5744 in the smaller cases such as 30-30, 32-40, 32 Spl, 38-55, 35 Win. and a few others probably because I have so many rifles sighted in for it, never chronographed any pressure deviations with these smaller cases and d*** it, I just bought two more 8 pounders!
Ill let you boys know how things turn out. In the meantime, life goes on.---------------------------Sixgun
Here's a pic of the case. The one on the left is the case I fired immediately before the spiked one. Kind of hard to see as I'm not much of a photographer, but the suspect case on the right has flattened lettering with a nasty looking primer.

Thanks for the update Sixgun. Hopefully, they may be able to replicate what happened. The 8 lb jug I have is much older than that. I also transfer some to a 1 lb jug for each of filling my powder measure as I reload.
After you posted your load, I went and looked at their website for loading data; they list from 30 - 35 grains for the .45-90, yet when they recommended my load in my .40-90SBN, they recommended a max load of 29 grains behind my 350 grain bullet. I'm sure that it being a bottle neck, there might be a bit more pressure, but I'm getting consistent loads in the mid- to high 1500fps range.
Look forward to what they say after they have a chance to inspect your ammo. Did you send the case in which the spike occurred?

I have no doubt that you are a competent, conscientious reloader but I am willing to wager that they will give you a hard time about mixing the contents of one container into the contents of another container, same powders not with standing. I wonder if different lots could cause such results? My hunch is no but.... The pains that the powder manufactures go through in the name of safety knows no limits. They do make mistakes however but they seem to invariably catch said mistakes, sometimes after a mishap like yours. Glad you are safe. Please keep us informed. 1886.
Jack nice pics That primer is scarey .
IM hoping someone can figure this out from the other post it appears all the bases are covered in what MAY have happened .
Now im not sure whatI want to do with my 5744 that I have left been using it for so long and with success ,but now im scared .
Looks like im going to be experimenting with new powders again after all these years .
The only objections I ever had before to 5744 was the unburnt residue and kernels which I always suspected was the cause of the fliers I got regularly that spoiled great groups with cast bullets.
OH well BACK TO THE DRAWING BOARD
