Neither, Might be ok on deer but not on elk IMO. Good 300wby,300mag,
30-338 mag should do it, why be limited to range. I've always figured maybe have alittle more rifle than needed. In the 30 pluse elk I have taken I've only used a mag rifle but have used a non-mag on deer. I wouldn't feel comfortable using a standard caliber for elk plus having no first hand knowledge. When I lived in Calif I took alot of deer with a 243,270,284,7x57,7x57AI,30-06 and 7 mag but once I moved to colorado and we had a combination season got to using a mag for everything. Now that we don't have to hunt in the same season for deer and elk makes it easy have just a deer rifle. I've got a 6.5x284 that I may use this year for deer and a custom 300wsm that may work. I know there is lots of fans of the 270 and 308 and were I hunt they just wouldn't work.
