Default RE: Reloading book error
ORIGINAL: crimedog

I have one of the One Book/ One Caliber reloading books for 300 win mag and looking at the Barnes section the 165 Grain using 78 grains of RL22 has a muzzle velocity of 3137, but 180 grain has a muzzle velocity of 3103 with 75.5. This does not seem right. Could someone check their reloading manual to validate this, I'm 99% sure this is wrong.
I agree that it sounds wrong, but there are times when a heavier bullet will get more velocity and energy out of a given amount of powder than will a lighter one having less inertia and bore friction. This may well be one example of such an instance.
