[QUOTE="Calvin45, post: 3076035, member: 109862"] Agreed. If you buy a .30-378 just to shoot a 180 grain bullet out of a 26 inch barrel that's awfully inefficient. Out of ordinary sized "hunting" rifles it's really hard to meaningfully improve upon the original .300 weatherby and newer .300 RUM in any worthwhile manner. Run a 30+ inch pipe and shoot 220-250 grain bullets and I hear the big case starts to flex its muscle. Sort of like trucks haha…my dad's former truck had was a Chevy/gmc with the big 454 big block v8. Horribly inefficient to just drive down the highway…didn't even have much more acceleration really than the older 305 v8 in the 80s truck before that one…but pulling a real heavy load up a hill that big 454 was just a beast getting warmed up and the smaller engine struggled a lot and couldn't possibly keep pace (if one was racing trucks with trailers up a hill like an idiot haha). Getting a .30-378 to shoot 180s out of a standard length barrel is like having a 454 v8 3/4 ton to haul…groceries! 🤣 [/QUOTE]
