Bullet Smoker Temp Question

Quick question, in a bullet type smoker with dual grates and a dome lid, think UDS or WSM, will the top or bottom grate be at a hotter temp? I'm getting 25* hotter temps at the top grate but thought the bottom grate which is closer to the heat would be hotter.

If this has been answered somewhere point me to the thread but I did a search and can't find my answer. Thanks Brethren!

I don't know what the deal is with my cooker but I'm about 'this close' to throwing it on the sidewalk with a free sign. BTW it's a UDS. It's consistent with temps but I can't get a read on what my actual temps are in the darn thing.

I checked both thermos yesterday in boiling water, both solid at 212, but today on the smoker I'm getting a 25* difference even when both probes are within 2" of each other. I'm using a Maverick ET-7 and a Spicewine. The ET is in a wood block on the grate and the Spicewine (w 4 in ch probe) is in from the side.

What is getting me p*ssed is that both good working thermos are giving different temps even when they're right next to each other.

I think it's time to start doing my homework on a WSM.

Thanks everybody. What I'll do it just watch only the spicewine since I already drilled the hole in the side! Reading both is driving me nuts. You shoulda seen me last week when I had a Weber thermo down the lid and getting crazy temps. Boil tested the weber and it was 15* low. Piece of junk.

Thanks again folks, I do appreciate it.
