I have shot both and can't say I noticed a big difference in recoil with those guns but recoil isvery subjective. I'd say bothreport more then a win mag but not a scary amount more, so if you can handle a 300 wm you should be able to handle either of these cartridges.

As to which one is better, well for me the "lack" of .323/8mm bullets makes the 325wsm a very distant second, even as a reloader.
