44 mag with AA#7

[02bigdogs17]

I am trying to load some 44mag's with a 200 grain flat point Raineer bullet. I have been told not to push plated bullets over 1200-1250 fps. And also that to load these plated bullets to use lead charge data or bottom end jacketed data. When I look at the lead data in my books they seem really light so I looked at jacketed data and for the powder I want to use AA#7 it says start at 15.6g and that it should be around 1270 fps. Anyone have any load data for this bullet with AA#7 powder. Thank you for your help.

Check out the data on Accurate's site. They have jacketed and lead loads, and there's not that much difference between them.

"When I look at the lead data in my books they seem really light"

Some lead data is for swaged bullets which need to be kept under 1000fps.
Some hardcast can be pushed to jacketed velocities.

Loading for a Desert Eagle, I found that AA#9 burned cleaner than #7 with full power loads. Also, even "maximum" #7 loads (from the chart I was using at the time) wouldn't reliably cycle the action.

Of the perhaps-a-dozen powders I tried, the #9 left less soot and flakes of unburned powder behind. Perhaps of no consequence with a wheelgun, but thoroughly cleaning the DE is tedious.

I tried to get AA#7 to work in my 44's, but had no luck at all with any bullet weight. I think I ended up giving the majority of a pound to another reloading buddy of mine.

For the velocities you're looking for with that bullet give Unique a try. It's pretty much all I shoot in my lighter loads, and really consistent.

Don't worry about pushing Rainier too hard in a 44 Mag.

I've shot them in another caliber at over 2000fps with no problems.

Just don't go over the listed max with #7 powder. Pressure will be an issue long before velocity will.

I stopped messing around with AA7 a bunch of years back. For hot loads, you cannot improve on 296/H110, and for everything else there is Unique. 10 gr Unique = 1100+ fps, 8 gr = ~900. #7 works great in 38 Super and maybe some others, but for the 44, it's the wrong fit for me.
