I’ve been using the 7 Mashburn Super since 2014. Set up correctly it’s a beast. It’s easy to make, 300 Win cases are everywhere and it has the powder capacity to launch heavier 7mm bullets to a useful speed.

But if you’re building a plain old 7 Rem set up correct is only going to lag 50-100 FPS at most. Just depends how deeply you wanna free fall into the rabbit hole.
