WranglerJohn,
How fast are you getting those TTSX's to go? Tried some in my standard Bob but not seeing the velocity yet.
Thanks!
Just shy of 3,500 fps with 48.0 grains of H-380 in a 26" 1:10' Schneider barrel. Thing is, in my rifle they have to be seated exactly .050" off the lands, anything less or more opens groups way up.
This is about as good as I can shoot these days with aging eyes. The diamond is .55" across the flats, a fouler and two blow-its but seven shots went through the group.
Great bullet.
Another good load is the 75 grain Hornady V-Max with 47.5 grains of H-380 and a Federal 215 GM primer 2.780" OAL at the same velocity (3,480). Tinkering with the primer type may improve the accuracy (.5") even further.
I use the Ackley for case shape that reduces (nearly eliminates) case stretching, accuracy usually develops below the maximum possible velocity.
