Ouch!
RE: 200 gr. in .284
The biggest issue with going that heavy is not many barrels out there are twisted for it. Look at how many years it took the 6mm crowd to go to a faster twist than 1-10" For the 6.5mm crowd it was pretty easy. The Swede's started that bullet @ 1-8.5" clear back in 1896. That's eighteen not nineteen. So, it came as a standard for that caliber. Unfortunately, the 7mm didn't stay with the European (Mauser) standard of 1-8.5" that the '92-'95 Mausers had, it got Americanized with the Remington 7mm Rem mag release of 1-10" I think that was just to simplify things. The 1-10" will stabilize 175 gr. round nose, but not spitzers. So, when Speer, Nosler and Sierra came out with these heavy bullets and no one could shoot them, they changed their twists just enough. Anywhere from 1-9" to 1-9.5". Now that seems to be more the industry standard. And until rifle and ammo makers started twisting some of these bigger calibers a little tighter they won't stabilize the 200's.
Hope that explanation helps. I also agree %100 with Rob01 that production is at max. Slowing down to make changes is just going to cause more delays. But, they are working up to it.
