18 lbs raw would be cutting it too close. I recently weighed a 4 butt cook and got 65% cooked meat with boneless.
Below are calculations that can be used with any meat:
(a x b) / c = d
then in lbs.
d / 16 = e
a = total amount of people
b = amount of meat per person in oz.
c = 100% - % of loss from bone or fat/cooking loss
d = amount of raw meat in oz.
e = amount of raw meat in lbs
example:
100 people, 6 oz of finished meat per person, 40% shrinkage
(35 x 6) / (100%-40%)
210/60%
= 350 oz.
350 / 16 = 21.8 lbs
