Have to admit that I've never fired a 308 out of any length barrel. On the other hand, I've fired lots of 7.62x54r out of Mosins, both short and long versions. It's hard to beat the sheer volume of a Mosin launching lead downrange. And the fireball is just as beautiful as the rifle is loud when you shoot late enough to fully appreciate it. And let's face it, there is a certain amount of pride involved in successfully getting all 5 rounds to load and shoot without a hitch while using a Mosin. Not so much with other rifles. Just sayin'.
