I voted with 'I like TTSX'. Prior to buying my 300RUM just for some laughs, I discovered there were no dies available to reload for it, tried getting some from the US, but that failed dismally. All I could do was buy factory, so Barnes 180g TTSX was my only option. I was rather surprised at the 10 shot group going under MoA @ 100, as my experience with TSX was not at all good previously, couldn't get them to group in either my 257AI or 25-06, 300WM or 338WM at all. In the end I gave away all those bullets and they weren't cheap either.
I also tried the 165g TTSX in 300RUM and they shot just as good as the 180's, so very impressed. Took a few deer for meat with them both and never kept one in, so have no examples of fired bullets.
Cheers.
