While I do like some new rounds, some I just don't understand, but I'm sure some guys love them. For instance the .308 win case, i understand, but I like the .243 and 7mm-08 even more for this case, if i want heavier bullets/more velocity I like to go up to a .270 or .30-06 case, and again if i want a bigger bullet or faster, i'll step up to a .300 win mag or .338 mag, I'm not a big fan of cases necked way down or way up.

I like the .375 Ruger, want a .416 Ruger even more though, also very little competition in the .416 caliber IMO.

The .30-06 case is plenty big at .308 caliber IMO, though I understand a .338-06 more so than a .338 federal, but a .370-06?

I think we have most bases pretty well covered, think someone once said we dont need new cases there's plenty of failed great ones already out there.
