STI barrel blank, Brazos comp, 2 holes, 5 inch tru-bore >3000 rounds

OAL 1.175

primer WSR

misc brass

Silouette 8.2g

MG jhp 124g

1385 fps

171 pf

Primers flat but not flowing.

When barrel was new <3000 rounds

7.4g silouette

1345 fps

For me Silouette is clean.

I clean my guns after every match or practice sesion though.

Are you sure on this one? 8.2 and a 124??? That seems really hot to me. Be careful there, those pressures have to be nuts.

Yep I am sure, olier chrono and area 2 cronos were both 171 pf. 1389 fps. + - 5 fps

I have backed off to 8.0g and do not flatten primers anymore.

1360 fps 168pf and shoots very good.

All crono's were done in Arizona 80 to 100 degrees fyi

I'm getting about the same thing with Silhouette through a KKM 5" barrel with 1 popple hole, 124 MG CMJ @ 1.163 OAL

8.0 goes 171PF and 8.2 gives me 174PF. The 8.2 load works the comp just a bit better than 8.0 grains. Primers are a little on the flat side with both 8.0 and 8.2.

One thing I have noticed with Silhouette, the SD for all of the rounds I have put over the chrono averages about 4 fps. Very consistent and reasonably clean at these levels.

I'm still working with True Blue and HS-6, the jury is still out. So far both of these have topped out just barely making 165PF. Also, plan to try some WSF and see how that goes.

WSR for primers.
