The groups were not good when I jamed them hard into the rifling and got exponentially worse as I backed them out.
I suspect Berger will be very cautious regarding the "thick"s performance on game. I'm confident that they haven't done the extensive testing as conducted on their 'regular' bullets.
If they made a "thick" in 277 I'd already know how they'd perform against NABs, BTs and SMKs and against standard Bergers. But they don't.
However I do have access to a 7mm RM that will be sufficient to test at LR velocities.
This won't be without its problems as I'll have to figure a way to keep my media from freezing.:( Another one of those bleeding edge things.
But the media functions very well for comparing terminal performance of bullets. I'm pretty high on it. Maybe I'll figure a different moisture additive such as antifreeze or some such thing. That would be a mess though. Or I could build a small fire under the container. I think I see a Darwin Award coming my way.
