I have 300 IPs I need to add to the PIX filter this week.
most are in ranges (ie, xxx.xxx.xxx.1 through xxx.xxx.xxx.50) over about 6 subnets
so, I'm hoping for a way to allow a range rather than doing 300 individual lines of code. Maybe cut it to about 10 or 20

You can only group by subnet masks.

Pretty much. You might want to create object groups if there is any change that different rules get applied to different IPs or groups of IPs
Which model PIX and what OS version?

Adding 300 lines of similar code shouldn't be too much of a headache?  You can manipulate using notepad/cut/copy/paste, and then copy and paste the notepad output straight into your telnet window.

We can do port ranges in access-lists, but not source or destination ip address ranges. Only subnets.
At least with the 515 you have enough horsepower to parse through them all. I hope you're using turbo acls....
