Can chop saws cut squarely?

[WSSix]

I'm borrowing a DeWalt 871 right now while I work on building my sub frame connectors. It's doing a good job but tends to wonder a bit to the outside as I get towards the bottom of the 2x3x.120 steel I'm cutting. It's not horrible but is noticeable. I'm not forcing the saw down either. I'm just applying pressure and letting the saw do its thing. Am I doing this correctly or is this the best I can hope for with a chop saw?

I'm in the market for one too so any recommendation on brand and model that does cut squarely would be appreciated if it's this saw that's not so great. Some of the reviews I'm reading lead me to believe that's the case but I just wanted to make sure.

I'm using a 14 inch, 7/64 thick friction wheel to do my cutting.

Thanks
