EKM,
I also thought the same thing as dedicated elker,I belive you should hunt with the largest caliber you can handle(even minor discomfort),I also know that any caliber under .270 is iffie on elk there is alot more at stake when shooting wind,angle, bone ect...If it was me and I had access to the .338 I would switch scopes (if of quality)and use it,but hey thats me not him or anybody else
