gene,
When I go to the local slaughter/ butcher shops in my area for whole briskets what I get are not the untrimmed packer briskets that weigh 12- 13 lbs. like most folks speak of on here.
It has the point/fat/flat on it, but the flat is always thinner. It seems they use the rest of the flat for ground meat or something. So it only weighs about 7- 8 lbs. Maybe that's what you have?????
