Talk about a step in the stupid direction. I know y'all wanted bottleneck cases and you should want them but what they've opened up by keeping that idiotic caliber restriction is .50BMG deer hunting and .375CheyTac deer hunting and not a lot more. Think about it. They've basically listened to the "we want bottlenecks" brigade and completely lost the thread that the masses want bottlenecks so they can use much smaller bullets going dramatically faster.
Instead of enabling the use of the classic .270win or .30-06 or .243win or, hell, even a .338WinMag the result is to enable the use of darned near anti-aircraft guns. What's the smallest modern bottleneck .35cal? How about as you climb up to .37cal or .40cal or .50cal? As you climb up the caliber ladder a little you do find some gems like .458Socom but that's kind of just out there on its own. The only other 35cal loadings (or 40 cal or 375 cal or almost anything in this caliber range) are either monstrous anti-materiel level beasts or are extremely archaic like the .348win and it gets worse as the caliber increases. The only thing that's remotely appropriate that I think you could still find retail ammo for would be the .358win. Incremental gains are sometimes just stupid in the extreme when looked at rationally. Thankfully this will likely result in all bottlenecks being allowed soon and perhaps they'll say no .50BMG for deer in Iowa and fix their earlier <cuss word> up.
