whats up fellas, stumbled onto this forum by accident thru google, but after reading had to join and put in my 2 cents. 400gr .44 slugs? i must have them. the heaviest i could ever find were 325s. i dont really use my loads for hunting as much as just for shooting econonmically. personally, just shooting and trying to manhandle a 400 gr load outta my 629 8 3/8 would just be fun and actually trying to hit something with it would be worth the wrist-ache. though i have a feeling my wrists are a little younger than some of yours. and ive also read that a grizzly's skull is thick enough to deflect even .44mag rounds...probably an old wives tale but perhaps some of you guys would know more than i about that
