Different code trains have different limits on HSRP sessions.
This is in addition to what may be imposed for different Supervisor engines.
If you have too many for the supervisor load they will become unstable.

Subject: [c-nsp] sup2 VRRP/HSRP limits

Hi All,
What is the maximum number of VRRP groups which can be configured on a
6500/sup2? I've found that the limit for HSRP seems to be 256. Do these
limits increase on the SUP720-3BXL?

I'm trying to use a pair of 6500s as the default gateway for a couple of
thousand VLANs, and am looking at options for redundancy.
Thanks,
Andrew
