I have seen this mentioned elsewhere. But i am unable to find any data from a powder manufacturer.

Therefor... I do not believe it to be accurate.

I see on my jug of W748, that it says low flame temp, longer barrel life.

Marketing BS? Truth?

Facts?

Anybody have a chart? If so, where did it come from?
 
I'd love to see a chart also, but I don't think it exists like that. I have read that ball powders burn cooler than stick, but of course I can't prove it.

I can say that I've put a couple of 8lb jugs of 748 through my first AR starting back in the 90's, and the bore still looks pretty decent. Chrome lined bore so maybe it would look the same with Varget, who knows.
 
Thanks to Ackleyman who posted link a while back:

Strange, link worked yesterday...doesn't today

I stand corrected, there is a chart like that! Thanks HM.

I do have a question. Aren't A2230, and Ramshot exterminator supposed to be the same? As in identical? Yet on the chart, they are 200 degrees apart...
 
thanks for the chart, I missed it. Good info this..
Anybody know what the units of heat are for this chart ?? TIA
This also looks several years old, missing some of the newer ones.
 
I found this chart searching around before i posted this thread.

It seems like a nice guideline.. But with no idea of who created this data, where it originated, when it originated and how it originated. I don't have that much faith in it at all.
 
Varget and H4895 users take notice how hot it burns, explains a lot on why it is so hard to clean the hard cooked on carbon out of the barrel....ROUGH on throats!
