Now im thinking titanium bolt and carrier. Anyone heard of someone trying that.

Not sure if this will help, but these two dudes are using Trail Boss for their subsonic loads. One guy was using cotton as a filler to get more consistent velocities.

Also, are you using a can?

I use Trail Boss and a can.

Tangent . . .

I used Trail Boss in some seriously reduced velocity .308 loads (for a child sized new shooter) behind some 130 grain bullets and it worked magnificently. I expected it to leave a nasty sooty mess in the gun, but it did not.

When I read posts and articles about subsonic loading, most people fail to mention temperature considerations. 100 F = 1159 ft/sec, 10 F = 1062 ft/sec. Load for a hot day and not so quite on a cold day.
