[QUOTE="Jesse09, post: 1054964, member: 88547"] Ramrod79, I have the Barnes manual; it doesn't specifically list the TTSX, but the Barnes tech advised me to use the data for the TSX BT, and I'm doing that. One thing that confused me was the listing in the manual of C.O.A.L. of 2.745". I asked the tech what it referred to, and he said it was simply the cartridge overall length of the cartridges they shot to establish the loading parameters listed in the manual. Today I loaded my next round of seating depths to test; among them is one loaded to the C.O.A.L. of 2.745". This results in a bullet that is .220" off the lands in my rifle. That's a huge gap and one I never would ordinarily try. Adding to the uncertainty is the fact that I am loading the TTSX, whereas the data was obtained with the TSX BT; I'd imagine the ogives are not identical. BTW, do you remember what your seating depths were? Close to the lands or big gaps? Jesse [/QUOTE]
