butt quanities.

I usually figure about 4oz per sammich, two sammiches per person. I get about 50% yield on butts if they're boneless or 40% bone-in, so you're looking at 5 of those 4-5 pounders and you should have a little room to spare.

Can't speak for the Sams or SuperWallys as I go to Costco.

I would check the Super Walmart. The Super Walmart here in Dayton carries 7-9lb cryovac Butts. I usually have to buy several at a time because the store sells out pretty quick.

You can cook the chunks just fine.

I would suggest that you go to any market that sells country ribs,pork steaks,cut butts,etc. and ask them for whole butts at their promo price.

They should be happy to sell them that way,as the don't have to cut,package,display them.

They ship to the stores in 2 pack cryovac,which will freeze forever.

Like Robbi said,I figure about two 4 oz sandwiches per pound raw bone in butt.

A two pack of butts is about 15 lbs,which yields about 30 four oz or 24 five oz sandwiches or 20 six oz.

Better to have leftovers,as too little.

For hunters ,I'd buy a bigger bun and give a better sandwich.

I am sure that the leftovers won't be a problem to take care of. I did some a while back and brought to work, I don't think David Copperfield could have made disapear any quicker,.
thanks
