i'm not condoning buying anything that you should be sitting in, above the ground, if you are over its "advertised weight limit".....but hear me out.
these companies have a high liability on their hands by manufacturing products sch as this. they are "forced" by their insurance carriers to advertise a lower weight limit than the product will actually hold. its not only safe for them, but safe for the end user as well. if you weigh 310, add onto that your clothing, any gear youll be carrying, your bow/gun...youll be surprised to see your now weighing in the neighborhood of 350. will the stand hold that weight...most likely (note..i'm not going to say absolutely), but the manufacturers have a buffer they place to keep people from buying it sayin..i'm only 10lbs over the limit...only to add nother 30-40lbs of gear to the mix and be WAY over the limit. if it was me..i'd spend the extra money on the stand that has the higher limit. it will be sturdier anyway, and you wont be sittin up in the tree worrying about when or if the stand is going to buckle out from underneath you. imo, you probably wont enjoy much of your hunting while in a stand that your questioning its weight threshold.
like i said, WILL it hold...most likely, not much of a doubt in my mind. would i personaly try it, not a chance in the world...my life is worth more than a few extra dollars for a tree stand.:cheers:your life life is worth more than that also, your friends and family would probably agree as well.
