[QUOTE="Jon A, post: 72073, member: 319"] Many here probably know most of the Hogdon powders we use are manufactured by ADI and data can be interchanged between equivalents. Most seem to think this means they are [i]the same.[/i] For all I know, they might be exactly the same. However, I just picked up Quickload a couple of days ago and noticed the powder property data they have for the ADI powders and the Hogdon equivalents are different. In most cases, it's pretty much a six of one, half a dozen of the other--they're so close you could use them interchagably and never know the difference. However, this isn't quite the case with AR 2218 and H50BMG. Their properties differ by a fair amount. One can still pretty much use the data interchangably since when loaded to the same pressure the charge weight will be within a couple tenths of a grain.... So why the hell am I asking if the same load gives the same pressure with either powder? Oh, because Quickload predicts around 110-140 fps more velocity with AR 2218 compared with H50BMG in the 300 RUM, for example, with most bullets--with the same charge weight and same peak pressure. How in the hell does it do that at the same pressure? Area under the curve, baby: [img]http://www.jonaadland.com/Hunting/50BMGvsAR2218.JPG[/img] Same [i]peak[/i] pressure, but a lot more total work being done on the bullet. Of course that's only [i][b]if[/b][/i][b][/b] the powder properties in Quickload are correct. And since this certainly sounds too good to be true, that's a "big if." I wouldn't normally dream of ordering powder from some other country, etc, for 10, 25 or even 50 fps.... But well over 100+ fps is hard to ignore. I gotta know! So, has anybody actually had a can of this stuff in his hand and tried it? Comparing it to H50BMG would be ideal--same charge should give the same peak pressure. But [i][b]IF[/b][/i][b][/b] Quickload is correct, the AR 2218 should give you an extra 100 FPS+. So if Quickload is full of it, it should be pretty easy to see in a side-by-side test. [i][b]If[/b][/i][b][/b] Quickload [i]isn't[/i] full of it, this powder could be the best thing since sliced bread for big cased magnums. Somebody tell me it's true....
