I have been considering building a few rifles. I would love to build myself and 28" 257 WBY Mag and with 5 Grand kids I'm sure some of them will want to shoot and hunt so I would Love to build a Deer gun for them (243 or 7mm08). My Grand kids ages range from 2 to 7 so I have a some time to get this done. My plan is to buy used guns between the end of our deer hunting season and Christmas when people sell cheap.
So my question is does it matter which action I use, Axis, Stevens or Savage?
I will most likely be buying used guns with the correct action length and bolt face size and replacing everything else.

Thanks
