I have also found the TSX much easier to find consistent load combinations for, than the
XLC. Barnes just came out with a 130 gr. TSX .30 cal bullet, so there is one in that
weight. I use the 130 gr XBT bullets, in my Striker, and as soon as I work out my issues
with my new .308 Win Encore pistol barrel, I will work up a 130 gr. TSX load, for that.
If I keep the Striker, I will be working 130 gr TSX loads up for that, too.
My experience with comparisions of XLC, and TSX, are with the 165-168 gr. .30 cal
loading for a 300 WSM, and 100 gr. loads, for a .25-06 Rem.
I struggled to find a 1 MOA load, with a 165 XLC, bullet, and eventually said,
"Good enough" to a 1.25 MOA load combo. On my first test groups, with 168 gr. TSX
bullets, I had one group .75 MOA, and another .85 MOA. I have yet to get back to
tweaking this first TSX load combination, so I don't know just how good I can get,
but it sure was easier to get to sub MOA, with TSX bullets, in my Howa 1500 300 WSM.
The same experience happened with load development for 100 gr. loads, for my
Tikka .25-06 Rem. The 100 gr. XLCs, after much experimentation, got to 1 MOA.
The first test groups, of 100 gr. TSX bullets, went sub MOA, and I had that load
quickly dialed in to .75 MOA. I believe I can even do better than that, if I tried
a few different powders.
Unless your gun REALLY likes 130 gr XLC's, I would seriously consider TSX bullets
over XLC bullets, if for nothing else, for the ease of finding consistent loads.
