Yup, there is only a tiny difference between the two offerings.
I see on the 175 SMK box, they also show 2600 fps, but they show a G7 of 0.250 instead of the G7 shown (0.257) for their new version.
I don't get wound up about published values, being happy if they are close enough to get started. If I were the OP and had DOPE for the SMK version, I would just go shoot this new stuff and adjust the DOPE till things are happy.
