One more data point, if you need it. Prior to GD (St Marks) taking the AA powder contract, it was produced by Lovex (Explosia in the Cz Republic). Lovex still sells that formulation as D036, and Shooter's World carries that as Auto Pistol. While there's been some drift over the years, the load data still overlaps about 99% of the time, and on both sides, start load is still well within the boundries. Lovex and Shooter's world both have current published data for 44 Mag. I've used D036 quite a bit, and all of the load data overlaps current AA5 load data, and past AA5 load data. I personally would have ZERO qualms with starting at the low end of published AA5 data and working up for 44 Mag. AA5 not being my first choice for 44 Mag not withstanding, but if it was all I had, I would dang sure use it without fear. Those who think "there must be a reason" are more than welcome to shy away from load development and stick to what they are comfortable with....but did it ever occur to anyone that there is no overly dramatic reason why that data is left out? But that its simply popularity and time? I mean....look, since AA ED1 was published there are what......half a thousand new cartridges? Hundreds of new powders? Come one......you'll also notice that Hodgdon chose to drop about 30% of the load data published by western powders. And for those who've been around a few years......Hodgon has dropped recipes from every powder maker they've acquired...why? Because it's not good? Don't be stupid. It's because if they kept all that data, their magazine would be 4 inches thick and cost 200 bucks. Load data dies away, doesn't mean it isnt' valid, just means that the publisher felt it was worth cutting in favor of something else. So fine, if you don't want to use it, then don't...but starting an argument because you're afraid to use it, and want other people to share your fear.....well, that's just another symptom of the nanny state....some of you guys on this board.....I wonder how you make it out of bed in the morning you're so freakin' afraid of life. Seriously, I'm completely convinced that there are members on this board who've been trapped at intersections for days because the "walk" signal was broken. For reals folks, if it scares you, don't do it.....or take the time to learn how to do proper load development.......but going on an on about how you thing something like old load data should just be discarded and never used again.......come on...take some testosterone pills or move to France where you don't need it to begin with. I fully expect some of you nanny state supporters to complain about this and get it deleted, and that's fine.......but somebody needs to stand up and tell people to stop all this nonsense about being afraid all the time about everything. Every time a crybaby gets his way...the nanny state gets a little stronger.
