I thought about adding the .50 cal but I can't afford a Desert Eagle. Things are starting to come together for me and I'll be buying a new handgun (and possibly rifle) so I would like to know what are your experiences with these calibers. I really would like to gather is some opinions on the power factor of these three calibers. I understand that the first two I'm asking about are autoloader calibers while the last is a revolver caliber. While I only own two semi auto's I don't have a strong prefence to autoloaders and will consider buying a revolver. This will be a safe gun and range gun. I don't plan on stock piling anyone of these calibers, I did that with my two 9mm's and that's all the ammo I need. So since this next purchase will not fill a self defense role of any sort I am open to any opinions but I'd like to stay with these three calibers... The 454 casulls, 44 mag's and 500 S&W's etc. I'd rather not own, just way too much gun for me.
