Subsonic .308win
Do any of you have subsonic load data for the .308win? Any powder/bullet weight would be appreciated, thanks!

About 11 to 12 grains of Trail Boss, 147 grain FMJ or 155 grain Match bullet.. or any 150 grainer of your choice..

rifle or pistol primers, doesn't matter..

I just started on subsonic loads. Decided to use the Lazer True shot 170gr lead bullets which come with the meplat and Fed Mag primers. Wasn't satisfied with the Red Dot some folks recommend. Unique worked good but more noise. The Trail Boss worked good but at much lower weights. 7.9-8.0 put me at 1045 fps. Of course the lubed lead bullet pushes easier which is why I picked it. One powder that is looking really good is the Winchester WST. It doesn't fill the case as well as Trail Boss but it ignites easy and is very consistent. At 6.5-6.7 I get consistent velocities and low report noise. This is from a 24" heavy barrel, 11" twist, and can. Will check the accuracy of these loads soon.

6.0 gr of Universal Clays and the 147 gr FMJ seems to work too. My Chrono is out of battery so I haven't clocked it. It shoot about 8" low at 100 yds. More to come.
