I haven't loaded/used the Scenar.
Pat's killed a bunch of stuff with the 139 Scenar and at impressive speeds. He gets good exits.
The 123 is accurate and I assume it would be a good WT bullet.
I did once have a problem with a 90 gr. Scenar at warp speed out of my .240. That one was too much of a good thing, too expansive, once was enough. The .240 is now a 100 gr. NPT dedicated gun, does super with that one.
