It has become quite common lately for both company's and even certain individuals on this forum to use deception in their ballistic comparisons between cartridges.They quote max loads in long barrels for the cartridges they favor or want to promote but use very mild loads or short barrel velocities to make their product or favorite cartridge to appear superior to other cartridges or in some cases equal to other cartridges that actually offer superior ballistics.In order to properly compare cartridges you must load both to equivalent pressures(or maximun design pressure for each cartridge) and use barrels of equal length.If you are reading these comparisons try to determine what loads and barrel lengths are being used before believing them.In any case increased case capacity will almost always result in a higher velocity potential for the same caliber or calibers that are very close.Don't be fooled by browning and winchester when they state that the wsm's will develop more velocity than the standard length magnums.Don't believe it when someone tries to convince you that the 270win is the ballistic equal to the 7mm rem mag or that the 30-06 is the ballistic equivalent to the 300 win mag.In all cases when loaded to equal pressures and fired out of equal barrels the 270 and 30-06 can't match the 7mm rem mag or 300 win mag and the differences are significant reguardless of what some individuals may tell you.
