LOL! That's too funny, Teeville. Pigs are deceptive. They're short and solid and weigh more than you might otherwise think. On the bright side (or not so bright side, depending on how you look at it) you probably won't get that much more meat out of them than if you'd processed at 300 lbs. The biological systems have three distinct phases of growth -- bone and organ, meat, fat. There is overlap, of course, but the major growth patterns go in that order. You'll get more meat out of them, but it won't be what you might think. Just because you double live weight doesn't mean you double dressed weight. So, fortunate on the storage/use side of things, but not so fortunate on the economics side of things. They also usually have a surcharge fee for anything over 350-ish if you're planning on paying for processing.
