I've always used Alliant 2400 for all my revolver and lever gun loads. I haven't seen any 2400 in a while, so I was looking for a good all around powder for 357and 41 magnum. I find load data for Accurate No. 9 for the loads I make. Looks like the loads will be a little softer than my 2400 loads but that's ok. I see No. 9 in stock at more than one vendor, availability trumps familiarity otherwise I'd just keep buying 2400. How do you guys feel about No. 9 for 357 and 41? Gtg?
I shoot it in 357 and it's great but don't lie to yourself about it being less than 2400.... I load 13.7 under a cast 154 and you know your shooting a magnum and dam accurate in pistol and carbine...
Accurate Arms #9 shoots well in the 357 and the 44 Magnum. It is my opinion that it also should work well in the 41 Magnum. The only complaint I have is my lot of AA#9 is granular, to the point of almost being grit. The little powder balls roll out of my Dillion 550B powder bar, and I have to regularly wipe the powder bar or it will stick. This powder is a magnum powder, it is not like Unique which works well high and low pressure. But, that's why you purchased a 357 Magnum Code: Smith & Wesson M27-2, six and half in barrel 158 LSWC 13.5grs 2400 R-P cases CCI primers 9-Oct-05 T = 64 °F Ave Vel =1273 Std Dev =44.03 ES =176.7 High =1372 Low =1195 Number rounds =30 158 LRN 12.0 grs AA#9 CCI500 Mixed cases 5-Aug-06 T = 104 °F Ave Vel =1278 Std Dev =34.98 ES =117.4 High =1344 Low =1226 N =27 Accurate little or no leading 158 LRN 12.5 grs AA#9 CCI500 3-D cases 5-Aug-06 T = 104 °F Ave Vel =1348 Std Dev =34.16 ES =134.7 High =1386 Low =1251 N =25 Very Accurate sticky extraction no leading 158 LRN 13.0 grs AA#9 CCI500 3-D cases 5-Aug-06 T = 104 °F Ave Vel =1360 Std Dev =33.19 ES =109.8 High =1393 Low =1284 N =26 Very Accurate sticky extraction no leading 158 JHP 13.0 grs AA#9 R-P cases WSP 9-Oct-05 T = 64 °F Ave Vel =1156 Std Dev =35.63 ES =160.6 High =1230 Low =1069 N =20 Very accurate 158 JHP (W/W) 14.0 grs AA#9 R-P cases WSP 9-Oct-05 T = 64 °F Ave Vel =1208 Std Dev =27.65 ES =89 High =1255 Low =1166 N =24 Very accurate 158 LSWC Linotype 12.0 AA#9 Mixed cases CCI500 14 Oct 2008 T = 80 °F Ave Vel =1217 Std Dev =52 ES =224.9 High =1346 Low =1121 N =29 accurate
Western powder v.8 .41 magnum .357 magnum It’s mostly better in .44 and .41 but there’s more data in the Lymans 48/49th for No.9 and cast. No. 4100 and Enforcer are the same powder.
Accurate No 9. Start low, work up.. https://www.thehighroad.org/index.php?threads/s-w-m28-2-357-magnum-high-pressure-locked-action.905609/
I use it (AA#9) in some of my .41M loads. You get similar velocities as H110 gives, with slightly less powder, For instance, a starting load of AA#9 is around 15.3 grains, where H110 would be 19.5 for a similar velocity, around 1100 fps. It's also a bit less than Win296. All three have a wide range in the .41M, but work up and look for pressure signs.
I like #9 better than 2400, which strikes me as harsher recoil. #7 is what I favor for mid level magnum loads.
Shooter's World Heavy Pistol = Accurate #9 as well. It's a great magnum powder, and it meters well. It's not quite as fine as H110, so you don't get the "leaky measure syndrom" like you do with H110. If you're loading on a dillon, default to the large powder bar same as H110 if the load you are using is large enough. It's also nowhere near as sensitive to case capacity as H110...IE, you have a lot more wiggle room downloading it, where as H110 tends to work in a narrow range and does not like to be downloaded. All in all, it's a solid powder, and well worth picking up a few pounds when available. As far as Shooter's World Heavy Pistol goes, you can use AA9 start load data (it mirrors and overlaps the Lovex/Shooter's World data), but you can not tail Heavy Pistol and AA9 as since Accurate Arms moved from Explosia to General Dynamics, the two powders have slightly drifted in composition.
My only gripes about the Accurate "Number Series" powders is that they always seem to require a slightly larger charge, and some of the "number series" powders are sold in 12oz canisters, not the usual 16oz (1lb) canisters. When added together this can make them fairly expensive to shoot.
No, Accurate No.11FS is WC297, which is the flash-suppressed, non-cannister formula of W296/H110. No.4100/Enforcer is between No.11FS and No.9, about on par with Lil'Gun.
