What is "overbore"?

Too much powder for the bore diameter. Its kinda weird, you'd think that would be "under bore" but its not but that's how it was coined.

Talon,

I've heard of Winchester, Remington, Savage and Ruger rifles, but what are "Noob" rifles? Imports??? Australian??

The whole term is "over bore capacity". As new slow powders are developed cartridges that were overbore aren't anymore. The .25-06 used to be overbore back when it was developed when the predecessors of 4064 and 4320 were considered slow. When 4350, 4831, and other slower burning powders came on the scene the .25-06 came into its own.

Oh, OK--thanks. I always thought it was "newbie." Guess not.

BTW--I wasn't serious!

Another label for cartridges is "balance". A "balanced" cartridge is one with a case capacity to bore size ratio which is efficient, meaning that bullet velocity is good considering the size of the powder charge. Increasing powder capacity results in higher velocities but each increase in powder capacity results in less velocity gain for the additional powder burned. An example would be the 7x57 Mauser compared to the 7mm Remington magnum or 7mm WSM. The 7x57 is more balanced, the magnums less balanced.

I dunno--might be "Bite The Wife." Maybe not. I'm not much at "texting!"
