I am pretty sure you said NOT A WILDCAT...now you are tossing them into the mix. I am a 6.5 kinda guy, but what you want may be slightly out of general reach. Now Kirby or Sinnarms *MIGHT* be able to put you into a 6.5 that will push that 127gr -- .468 G1 profile bullet out at the pretty much required 3800 FPS..... I would honestly hate to be the person paying for barrels however. YIKES.... time to take a reality pill..
It is going to be a bit hard to drive a BARNES Copper down range to 1k and retain 1600 fps...
I love the TSX and TTSX ect...but not so much for extreme range as the BCs even on the LRX is a bit weak.
Should be interesting to see what shakes
