[QUOTE="Mikecr, post: 663452, member: 1521"] Well, it's also a 'fact' that higher muzzle pressures (all else equal) hurts accuracy. And this is why longer barrels work better, and more accurately in large capacity cases, than barrels that are too short. Whenever you go to any extreme, with anything, you pay a price. You wouldn't want to go ridiculous long for a little more velocity, adding whip. And you don't want to go ridiculously short for accuracy, adding fireball. Both hurt accuracy. What point blank BR shooters do, is far far away from LR hunting/shooting with a rifle in 300wm. PB BR shooters can take advantage of ~22" barrels because they're shooting the tiny 6ppc with a very fast powder, resulting in low muzzle pressures despite. They're also using better releasing FB bullets. I would go 28-30" for a 300wm. With this, you can burn a hi% of the powder INSIDE the barrel instead of hitting the releasing bullet base with a giant blast of spiking pressure OUTSIDE the barrel. You can use a larger diameter & fluted barrel for stiffness/weight, get very clean bullet release, and better accuracy than you're gonna end up with from 20". [/QUOTE]
