First question I have is, is this army going to be used in tournaments or against friends? Basically I'm asking if you know who you're opponent is going to be.

The reason I ask this is that some of the units you have taken, such as the scraplauncher, are innefective against certain armies and good against others.

Something that you may want to take for your butchers is the hafling cook book, it's a pretty useful item, but the ones you got there are good as well.

Your tactic, using the ironguts in the middle and the butchers on each side in an ogres unit is good (Y) I actually use the same tactic a lot with success.

Depends on your playtesting, but you could also use a unit of Yhetees to replace the unit of leadbelchers. A gorger will also be a good unit to possibly add to this army. Once again, it really depends on who you play. Against Khorne, a gorger might not be the best of use, but against an army of nuln, it will work very well.

Overall, this list looks very competent as well as your tactics.
