I carried a whelen all year and never got to kill an elk with it. 250 npt’s at 2500. The whitetail came off his feet though.
I am always encouraging people to get another rifle.
So, your 350 Rem Mag is definitely a cool idea. 225 NPT’s or 200gr AB’s would be cool (i am not into barnes and be mindful of COAL). Get a full sized (short action 😍😍) rifle with 22” tube and you shouldn’t be much behind the whelen, in a shorter lighter package. I have been wanting to do that myself.
