Is there a way to denote the use of hBn bullet coating? The result of using it is typically a slight reduction of friction in the barrel, simultaneously with a reduction of pressure behind the bullet
Hello, excellent Video! I have a question: why do you change at the end of the OBT calculation the Isentropic exponent (k) and the Combustion coefficient (Ba) instead of changing the calculated optimal powder mass (mc)?
Hi, Stephan. My attempt to answer your question is out of pure ignorance here, but I think it has to do with the deviation factor of each powder lot. Each lot has a different deviation factor which runs unequal to the published data. I'm of the opinion that the powder data supplied on GRT is a rough guideline from many different testings from which this data has been collected over a period of time. As Cassie mentioned, we still have to change data on system according to our measurements, case cap, ect. That beign said, primer ignition consistancy also varies from lot to lot so I am of the opinion that we still have to adjust the isentropic exponent (k) and combustion coefficient (Ba) ourselves according to the velocity data captured from the chronograph. In other words, existing supply adapted to real world data. As with ES / SD, I'm not sure if this data would change once adjusted seating depth has been applied.
Thanks for the forecast! I have a quick question: My OKX wallet holds some USDT, and I have the seed phrase. (behave today finger ski upon boy assault summer exhaust beauty stereo over). What's the best way to send them to Binance?
hello, I have a question. Why do different results come out when calculating the BLT between Quickload and GRT? Is this due to the different powder data? It would be nice if someone would answer me!
Hi Cassie, het jy dalk n formule of excel sheet wat n mens die verskil in somchem se deviation bereken? Of is daar n manier om dit aan te pas op die program?
Hello, this is a very interesting video, even if I don't fully understand the second half. My mother tongue is German and my English is very poor. A translation into German would be very helpful. Gorden, that would be a great thing!
Hoping to eventually use this for pre testing loads to start an ammo company. Amazing work guys!

Excellent video!! Thank you!!
Wow great guys!!
I enjoyed your presentation. Did you ever complete the instructional video that you mentioned at the close of this video?

Why changing the initial pressure, and not the powder burn rate?
Dankie Cassie!

Thank you so much for this!
Great video!!! I know this was specifically for rifles, but does is OBT also useful for pistols as well or just rifles?

Top, danke!
That bloody piano. Lol.
Das Programm ist Super. Aber dieses Video auf Deutsch wäre Toll. 🙂
Bin der gleichen Meinung, die zweite Hälfte ist so etwas unverständlich, zumindest für mich!
There is one in German

Thanks for the video. Would have been better without the music. Not everything has to be a hollywood production.
