So, that half full can of AA#7 I had left from my beginnings, along with a full can that just happened on the shelf of the LGS a couple of weeks ago, have been talking to me.įor some reason, I'm thinking that a slightly faster powder than AA#9, like AA#7, with the 240 gr cast swc's may be a 50-75 yard "accuracy load" in either the R92 or the SRH. 38 spl, and much prefer AA#9 or A2400 for the magnum loads in. Lately, I've found that I really like AA#5 in both 9mm and. I ended up getting so hooked on the simplicity of using the Unique in my short barreled revolvers that I loaded very little of the #7 for them, and had such problems with the 9mm kit that I just put the 9mm aside until I started using the Hand Press and Lee 4 die sets. Neither were the "best" for any one of the three, but both were "useful".
I studied that manual for a day or so, searching for powders that would work for all three possible chamberings and picked two I thought would be best to start with. This group was made with the Hornady 200-grain XTP over 11.0 grains of Blue Dot. The M24-3 test gun turned in great accuracy with many loads. Our test guns are both S&Ws: a blue M24-3 made in 1983 and a stainless M624 from 1986. I got the basic tools together (with advice from a good friend) and an earlier release of the Lee 2nd Ed. But in 1956 Keiths efforts culminated in the introduction of the.
When I finally reloading a few sort years ago, I started with the Lee Loaders in 38/357 and 9mm. ĭoc, we started with the same experience it seems. High density, double base, ball propellant similar to Accurate. If anyone has any experience with AA#7, cast bullets in the. 44 Magnum cartridges, when slightly less than full powder loads are preferred. The substantially greater MAP allows launching light JHPs to nearly 1,900 fps and the heaviest cast gascheck bullets up to 1,250 fps. I figure that the 16.0 gr load is just a tiny bit over the Lee "start load", and still a bit under the Accurate Powder web site "max load", I may be in the sweet spot to begin with. data is substantially expanded to include 17 cast and jacketed bullets weighing up to 355 grains. The web site data shows a Start at 14.7 gr and Max of 16.3 gr (AA#7). The Lee 2nd Edition lists a Start of 15.8 gr and a Max of 17.5 gr (AA#7), but the current Accurate Powder web site data (as are most all the recent published sources of load data) shows a considerable reduction. It’s especially well-suited to the 357 Sig and 10mm Auto, with high velocities and excellent case-fill. 357 mag loads, I'm going to load a box of 240 gr swc's over 16.0 gr of AA#7 to give it a go. 9 is a spherical powder with a double base that is ideal for high power loads in traditional magnums like the 357 Mag, 41 Rem Mag, and 44 Rem Mag. Having a couple of pounds of AA#7 which seems to work well for those middle of the road. 44 mag brass siting idle and was thinking about a real "in betweener" load that may give adequate velocity and decent accuracy in both the 20" R92 and the 7-1/2" Super RedHawk. 44 mag, and find myself still enjoying the. The last couple of weeks or so have caught me tinkering with loading some caliber or the other 4-5 times per week.
