Muley that's Fahrenheit, sorry about that I should have marked it.

This one?
![]() Warning: The above graph depicts 150 grain volumetric loading pressure traces measured under laboratory conditions via radial transducers. These loadings that MAY be in excess of manufacturer's recommendations. The highest pressure load combinations depicted here are recommended and touted by many: Knight Rifles, Hornady, Thompson, and others. I obviously do not suggest their use, for equally obvious reasons. |
I did not have the same peak on 777 pellets but I did not do any thing out of the ordinary loading them either other than that it is very much the same.
|
The blue line shows a worse case broken 3 pellet load. Allegedly Lymann did this test.
The crazy thing is several SML loads make nearly the same curve as BH209 but can make about 10K more near the end which is the dangerous part if its not in an approved gun. |
Brought this back up so Chet could read it... Ray

Thanks I missed this thread altogether.I ordered a case locally but didn't ask if it was in stock at their distributor.I will try to find out tomorrow.nothing worse than backorders. It sure sounds good for my sidelocks

Cabelas should pick it up too since they stock Alliant powders. Then i can save the "black gold" for other things. Since my cheap/fun load is 80gr and a 180gr in the 45, im hoping it will get me at least the same fps for $5-7 less a bottle. :D
It should work well with the ACP and Variflame primer conversions too. |

If it reacts like 777 does with lighter loads and the 180gr....it will...ive seen plenty of chrono data for 80-90gr of 777 vs the same amount of BH209. In the 45s, BH209 starts to pull ahead with a heavier bullet or top end powder charges. On the light loads 777 is just as fast and the last Backmag was right in the same ball park as T7. Im also curious to see how it compares in the older Knight NFPJ conversion. I have one and the rest are all Lehighs.
