7x64mm switching from Barnes 140gr TSX to TTSX

[Milligan]

As per title, does anyone have experience of switching from a TSX to TTSX and if yes did it have any material impact on load as in velocity or POI?
They look the same but Barnes shows a 0.065" of difference in length, which I'd put down to the plastic bit instead of the meplat/HP.

usual caveats of work up, own risk blah blah.

Yes - 150 TSX to TTSX in my WSM.

Accuracy node for TSX was at 3150FPS roughly, TTSX appeared at 3340 FPS.

No node presented with the TTSX in a similar place to TSX.

This obviously did change the POI a few clicks.

Hope this helps,

Ben

Looking at the Barnes data online the two bullets you mention are quite different as they have different numbers of relief grooves. Its a case of working up the load again I'm afraid though it is possible that you will get the same answer!

meh, I was comparing a seated TSX so missed the extra band. It looked to me like the difference was the blue bit of marketing sticking out the end.
Anyone with practical experience in 7x64 arena with Reloader Swiss?

Fox 130's over RS60 for me in the 7x64.

Running at an average of 3006fps from memory. Knocked over everything from roe followers to forestry stags.
