I thought the 270 and the 300 were a bit of overlap...
I suppose the .270 and .300 are kinda close, but the .270 with a 130 gr bullet is brilliant for NA antelope and deer. The .300 works for everything else.
The .270 barrel will also be the next step up my son will take from the 6.5CM, so there is a plan to it.
@Forrest Halley I think the .300WM and .375H&H are fat enough apart to justify both. I wouldn’t want to shoot the .375 off a bipod at an elk at 400 yards. I’m sure it will work, but that is not really a bipod-prone-shooting caliber. (Note: Im not a big guy)
