Hello
Just got a copy of the new Sierra manual and of course looked over the 10mm data.
They have included a lot more powders than the #5 manual, and have increased the loads for several others.
Interesting, the narrative states that AA#7 and Blue Dot are outstanding performers, but there are no loads for Blue Dot in the manual.. ?? Oops..
If they included 3N37, why not 3N38?  I wonder what they didn't like about 800-X or AA#9?..   They actually listed loads for AA#9 in 38 Special loads...

Here is the list for 180gr;

Clays                            5.3
Titegroup                     5.8
American Select           5.6
N320                          5.8
BE-86                         8.1
Zip                             7.0
Unique                        7.2
Universal                     7.2
Power Pistol                 8.2
N340                           7.1
True Blue                     8.5
AA#5                           9.3
Auto Comp                   7.7
CFE Pistol                     7.6
Silhouette                     8.2
3N37                            8.7
N350                            7.8
572                              8.1
AA#7                           10.9
Longshot                       8.3

Accuracy Load                       9.3  AA#5
Hunting Load                         8.1 BE-86 

I agree with the accuracy load.. AA#5 has always produced tight groups.  But the hunting load, not so much..

Interesting! Thanks for sharing!

Does it have any load data for 200gr bullets?

No, because Sierra doesn't make a 200gr bullet in 10mm.  180gr is as heavy as they go.
