First Time Boston Butt...Assistance Please!

HolySmokes

After a few months of wonderful salmon, chicken, steaks and an occasional burger, I'm trying my hand at a nine pound Boston butt tonight. I have Mickey T's rings, so "dialing in" a temp, is relatively easy. However, with one, I run about 270 degrees and the other, 258 degrees with the weather conditions I've been dealt. What temp should I try to lock in for the evening?

Holy Smokes,
Of those two: 258 gets my vote.

BBQfan1,
Considering your credentials, 258 it will be....and thanks so very much for the quick assistance. The Tanqueray No. 10 will be lifted in your honor, Sir.

Holy Smokes,
I agree 258 would do just about right.[p]Tom

Holy Smokes,
258º should be just fine but if you play a little with the lower vent you can set that puppy right on 250º, but like the others have said 258º is nothing to a butt cook.
Good luck and let us know how you make out.
