2225 is too slow burning for 300wsm. Especially with 160-180 grain bullets.
I had a long barrelled jobbie and seated out to nearly 3.200" inches, I could just about get enough 2217 in the case to match the speeds I could get with 2213sc. That was with a 208 pill.
2213sc or 2209 would be my pick for 160-180's. That should be backed up by ADI's load data if you go check their site.
