200 is too much. Even 180gr is pushing it and some bullets need a 1:8 twist. Depending on the bullet they might also need a longer than average magazine
like AI/AW system.
The 180gr can be loaded at comparable speeds than the tipical 175gr 308 but might also need extra freefore. My latest chamber can actually take the 180gr ELDX
from hornady and Berger VLD but I have not gotten to do any new serious load development with them yet specially because the 162gr and 168gr do so well.
With 1400 yards of supersonic range is plenty for whatever one needs including long range hunting improving ballistics and terminal performance vs all other
popular 6mm, 6.5mm and 308 itself. Of course up to a reasonable range that is why the 7mm and 30 cal magnums are out there.
In the long range hunting and sh forums there are guys shooting 180s and 195's with long free-bore and even the inexpensive Savage axis can be retrofitted and
upgraded to shoot some amazing loads because of the nice magazine coal. It is actually a pretty strong action but one has to re-barrel and also find a chasis
for it. The action is also cut shorter to put a regular recoil lug and also everything is bedded. otherwise factory barrels are great. The savage precission carbine
and predator (not the xp) will take the axis semi bull barrels that shoot like match barrels from those amazing actions and on a budget. I hope bergara releases
a B14 and tikka a T3 PRS in 7mm-08. I think those should sell well among folks who understand ballistics and want to have an edge w/o going crazy on budget.
This is how the 195gr VLD looks like loaded for extreme long range.
