I just bought a 44 Automag and a Wildey in 45 Win. Mag. and I need some load data, any sources?

My Hodgdon yearly manual, the magazine style one, has data for both.
I`d check the powder companies web sites and see if they have any listed. (the best place to look for RELIABLE free data)I`m sure they`d have some available if you wrote and asked, I have seen 44 auto mag loads in some older manuals I own, and most have 45 mag data yet today.
BTW, I don`t remember the load, but I used H110 under 180 Sierras in my auto mag. Shot like a rifle, very accurate! The action was quite stiff and full house loads were needed to cycle the action at that time. I don`t know if the later ones or more worn ones act the same, I sold the gun back in the early 70`s -1973 or 74- and have kicked myself ever since.

You can get a lot of loading info. directly from the powder manuf.

The older Hornady manuals also had data. For the automag, you can use loads for the .44mag, start w/ loads in the middle & work up. I would not shoot the 300gr in the automag, the pistol was designed for 240-265gr. You'll just excelerate wear.

if its any help my loads for 45 wm are 16 gr unique and a 185, 21.3 gr blue dot and a 185, or 17 gr bluedot and a 230. I like the lighter bullets cause they do blow up a crat nicely, but they are a bit difficult to get to function.

my loads are for the origional pistols , 230 grn bullets ,26 grs h110 to start , 26 grs 296 ,23 grs 4227
260 grn bullets ,24.5 grs h110 ,19 grs 2400 , 10 grs unique ,11.5 grs herco,24.5 grs of 296 , these are in the speer number 12 maqnual and all are starting loads !
the automag is harder to find loads for , but you can use starting loads for the 44 mag and work up from there , but go easy , and use the ball or stick as i didnt like the results with the flake powders .
