Been there, done that. The 270 will give complete penetration on an elk. If you prefer to use it, by all means, do it. There isn't an elk that will not fall over if hit properly with the 270. I will be planting another one in a couple weeks with "OMG" a 270. I don't care if you hit them with a 475 A&M, if it isn't in the boiler room, it don't work.
