Well, let's start with Hornady... my choices are 200 grain FTX (which... meh?) or three flavors of Interlock. Now, I like Hornady, but I don't like the Interlock or the Interbond especially much. I wouldn't call them outright bad, but my preference is overwhelmingly for the SST if we're going old school or the ELD-X. If anything, the .375 choices are worse if you're not looking for a solid, but that 250 grain CX should at least be screaming out of the .375 Ruger... haven't seen any reports on CX performance though.
Sierra offers two choices that I see... a 225 grain soft point might be compelling if they didn't handicap it with a "heavy, double-tapered jacket." I'll pass on the 200 grain soft point... not gonna soak up the recoil of a .35 Whelen or Norma to pitch something with the aerodynamics of a brick at my target. I'd sooner take a 200 grain Partition in .308 and call it a day. I don't know what happened to the Gameking, doesn't seem to be in the catalog anymore... it would be preferable to either of the aforementioned.
Berger... Bueller? Bueller?
On the bright side, Nosler makes two flavors of Partition, and that's a classic! The downside is that they're made by Nosler... and $2 a pop for the projo alone is rough. They also produced a 225 grain Ballistic Tip that I no longer see in the catalog. Candidly, it's not that I can't afford Nosler projos, but I simply refuse to buy them on principle. The fucking audacity to charge what they charge, across the board, tells me they have a strong fan base... and I have no interest in paying for the privilege of joining it.
