I friend of mine got a Savage Model 99 from his father's estate, with eight other lever guns of various kinds. I'd never been a fan of lever guns, but the 99 changed that. I liked the balance, and the rotary magazine. And it was chambered in .300 Savage. I remembered the .300 thread here, so I looked up the specs of the cartridges.
Wow. The pressure and velocity are all over the place depending on where I look, but for the same bullet weight the .300 gives up a negligible amount velocity for a whole lot less pressure. It's down in the .30-06 range in pressure, but overlaps .308 velocities. WTF? I guess tiny differences in case design can make a big difference in pressure.
I *like* the .300! An AK in .300 would be way cool. Hmm... I wonder if an SKS could be converted to .300 without major work. [doubleplus ungood badthink... must... resist... too many projects already...]
