Hey guys , so I just bought some silhouette to use in my 10mm for our outdoor pistol league. I'm on the last bit of my power pistol that shoots extremely accurate for me, but cannot find any. So I've read lots about how well silhouette works in the 10 but haven't seen anyone post about where on the loading data gives the best accuracy. Shooting a RIA 1911 180 grain rmr jacketed bullet , winchester primers , star line brass . I have downloaded the western powder reloading guide so I'm set on data just looking for what you've found to be the most accurate. Thanks in advance for your suggestions .
Welcome to the forum Rob-c! Silhouette does work well in the 10mm, I haven used enough to say what is the accurate loads for particular bullet or weights.
This is load data we have posted here in the reloading section.

In the downloads we have seen some companies use Silhouette powder and pushing more for velocity than accuracy.
Good luck and please share your results! ;D
From Chuck on GT back in 2011 using 180Gr XTP's this is one of his best ES / SD loadings
G20 with a Lone Wolf Barrel (stock length) along with a 22# recoil spring riding on a stainless steel guide rod. Cases are Starline shooting 180 gr. Hornady XTP JHP. The chrono is a model F1 Shooting Chrony. Distance from chrono was 6 feet. Ambient temperature was 45 deg. with overcast skies. C.O.L. were set at 1.258" - 1.259" WLP primers are employed to light the fire.
As a disclaimer I must inform you that these loads are what I use (and have used) and in no way do I take responsibility if you blow your s**t up! Proceed with caution.
So here we go. Let the chips fall where they may.
