Posted this and all the details in the Target shooting forum. Occurred to me that this may be the appropriate place..
I think this weight (295gn) is ideal for the Texan's twist rate. NSA is on to something. Finding a bullet that gives the advertised "500 ft lbs" is easy, just load the heaviest chunk of lead that will fit. Power AND accuracy is what has eluded me (and maybe other Texan owners) until now. I'll be ordering these in bulk quantities, haha"crittahitta"Nice shooting. Looks like you found an excellent round.
"Tethered" sorta. My tank was down to 3100psi so I left it attached to the rifle. Wanted to eliminate that variable and see what the slugs can really do. Once I wean the gun off the bottle, I'll need to shift POA from shot to shot to stay under 2" at 100 (I think)"nielsenammo"Did you shoot this tethered or filling every few shots?
