Hey there, you're tying to make too much sense! Don't you know a .284 wont shoot through a paper sack while a 6.5 hits harder with it long BC, blah blah, blahI have been all through that and I am over it now. I designed my own wildcat, had a reamer made and the rifle made up. I have so called improved chamberings etc. Been there done that.
Now I look more to the rifle since I finally had to admit that there is a lot of overlap in cartridges and bore diameters.
Do what you want.
