I haven't used the tsx in my 7mmstw rifles,but the 140gr mrx averages 5/8" at 100 yards and around 3" at 400 yards.Even with the poly tip,the mrx does drop a couple of inches more at 400 yards with the same sight in.The grooves do lower the BC enough to notice at longer distances.
I've been waiting for you to chime in here
. You said the MRX drops a couple more inches at 400. What other bullet are you comparing that too ....if any ?
I just looked on Barnes's website, and saw that for '08, they are making "tipped" TSX's. That should be interesting. I havent' given up on them yet.
Just out of curiosity, what kind of velocity were you getting with the MRX's in your gun ? I bumped 3500-3530 with the 140 gr. tsx's afew times. But I'd get a ejec. pin mark every couple shots in my factory barreled rifle.
