Chuck Roll Questions

Going to smoke /grill a 23 pound chuck roll (quartered up) for a celebration of life. I’ve done a chuck roast from the roll cooked to 203 degrees and it turned out awesome, pulled beef you could call it.
My questions are this: Do I go the the pulled beef route or cook the roast less so I can slice it on my slicer.

If I go the pulled beef rout I will separate the meet in the a roaster pan trying to keep the bark in place. I don’t want to treat it like pulled pork.
I would like to make the meat for use as a sandwich or just a serving on the plate.
Any Idea what temperature to go to for slicing if I go that route?

I will be using a an old brinkmans but like new commercial smoke with a side mount burner.

Any idea how far 23 pounds will go as feeding a group? I know there will be some loss in weight when said and done. Just wondering if I should do pulled pork also.
75 people more or less expected.

pulled pork or beef will go further than sliced meats.
I figure a quarter to a third of a pound per person depending on how big of a sandwich they want.
also figure about a third of them will want two sandwiches.
at least thats my experience with a bunch of starving Iowegians.

I would bet your chuck will cook down to around nineteen pounds if it has a lot of fat on/in it.
if you do a pulled pork as well and you have a bunch of left overs vacuum seal them up and save em for later !!

Good combination is too combine both pork and beef and mix shredded.

That is a awesome. The pork suppports the beef a lot.

Figure for 1/3 # of meat per person. Cooked weight.

Thanks guys. This helps put things in perspective.
I will do the pulled pork also and do as you suggest riverruns. 3 separate dishes will go a long ways.
I have a feeling 75 people maybe on the conservative side. My Uncle touched many lives through the years. Being an avid sportsman most likely they will out number the family and we know how we like to eat good BBQ.

There was talk of catering but I heard that and I said “Nope, I’ll take of the main food and the rest can be pot luck”.
Sheldon didn’t think of the left overs. We are having a gathering at the lake cabin with close friends and family be good food for coming off the lake.
