In the 6.5-300 why not the 127 gr LRX ?
Barnes LRX
The Barnes LRX is a homogeneous bullet, meaning it’s made out of one solid material, which happens to be copper. It has only one weakness: Since copper has less mass than lead, LRX bullets are inherently lighter than a lead-cored bullet of the same size, resulting in somewhat lower BCs.
Where the LRX really shines is bullet integrity. It will expand reliably down to 1,600 fps or a bit less and up to, well, however fast you want to shoot it—and that’s where the real magic happens. Even if the four copper “petals” that expand outward and roll back into the classic mushroom shape on impact shear off of the main shank, it’s impossible to batter that shank too small to penetrate.
It will always drive deep, and even if you only have a .284/7mm-diameter blunt-fronted shank pounding through heavy bone, dense muscle and vital organs, it will penetrate and kill.

Additionally, if some or all of those four petals shear off, they become satellite projectiles and wreak their own share of havoc. In fact, according to Lead Ballistician Thad Stevens, Barnes is intentionally engineering more and more of its hunting bullets to lose petals during penetration.
Personally, this is the only purpose-built long-range hunting bullet I’d trust if I had to shoot a big moose quartering to me at very close range, and count on it to drive through that massive shoulder and go killing-deep into the vitals.
As for accuracy, while it’s frankly not a match-grade projectile, the LRX tends to be very forgiving through a broad selection of rifles. I’ve had Weatherby and multiple custom rifle makers tell me that the Barnes bullet is their go-to when qualifying rifles for an accuracy guarantee. Whether that guarantee is one MOA or a half-MOA (which I’ve personally seen many LRX loads achieve) that is a resounding accolade to Barnes bullets.
