Brass

[RiverNotch]

I like this, though I can't be sure if I'll still like this a month from now -- something about the middle section feels a bit scattered, but I can't quite put my finger on it. Slightly bothered by the lack of full stops, since their existence would definitely make this poem punchier, especially with the last stanza.
BRASS

He was thirty three but feeling one hundred
in this room, there was no room Comma doesn't feel right -- doesn't give the pictures of the two rooms enough space. Should be em dash -- not even a semicolon would do!
besides for making bullets A full stop would make this punchier, I think.

Overhead hung three hundred points
of antler dead almighties watching I'm thinking "of antlers, dead almighties", but even though that would be more correct, "antler dead almighties" is a very strong thought for me -- maybe a bit too strong, especially since that style of thought-mongering doesn't appear anywhere else here.
him and how he was thinking Sonically, a strong line, especially with the play of "h's", "ng's" and "a's". 

He must of stubbed ten thousand plus "must have".
cigs into the arm of that dumpy walnut chair,
dumb hands all-knowing The interplay between "almighties" in the last stanza and "all-knowing" here feels inappropriate, unless you really wanna get into that cosmic (for me right now, demiurge vs gnosis sort of shindig) discussion, in which case this needs a big rewrite.

He must of handled one hundred thousand casings "must have". The hyperbole of the numbers here is a bit bothersome, but with the omnes, I get why they're there -- and they sound very good too, with the "ten" being sharp, the "hundred thousand" having corresponding consonants to all the befores. Still, though I see the progression, something less than exponential for the sake of, well, realism, would be better appreciated, I think.
on that press, and smoking snouts was dumb to do Yeah, snouts sounds a bit wrong -- an unnatural wording for the sake of, here, very obvious sonics. "cigs" would be the dependable choice, but for a poem this sparse....hmmm......But I do think that even though "to do" makes this line a bit too long, its rhythmic push still makes it a keeper.
around all that gunpowder 

But after awhile, he quit caring; Regardless of your lack of proper punctuation, this should be a colon. And "a while" is different from "awhile" -- awhile generally means a fairly short period of time, while a while means an undefined one, and judging by your separation of the strophe here, I'm guessing you meant the latter.

He liked his tobacco, This and the line about the gunpowder are very delicious -- the interjection of these two objects right where they are feels just perfect.
His fingers felt like brass Again, this is where you'd really benefit on using full stops -- the comma makes the two lines' images flow into each other too smoothly, robbing a bit of the power from the very strong image at the end.
