I have looked at the .270 wsm, 7 mm wsm , the creedmoor, several a.i .chamberings and I see no advantages. I have a neighbour that regularily brags up his 270 wsm , his loads etc
One day I will put his rifle over my chronograph and compare it to my WCF.
My rifle has a 22" barrel and the 270 wsm a 24.
His jaw will be surprised when he sees the tiny difference over a chronograph. I easly push 150 partition 's at 3040 from the. 270 Jack. That is good elk medicine, Jack.
On deer sized animals It is too much , imo.
The. 243 is a better whitetail chambering but a little light on larger bodied bull elk, imo
