Coues32: I am glad so many folks have made suggestions that directly apply to your inquiry.
So that gives me leave to make this "suggestion" in case I could tempt you - don't buy a light weight 204!
Buy a heavy barreled 204!
All of my 204's have heavy barrels and I tote them about often and without hinderance or fatigue!
Then, when a Jack Rabbit or a Coyote or Fox gets antsy and runs off I am more apt to connect with them using the heavy barrel 204's.
I have a number of "LW" Varmint Rifles including ones in 17 Remington, 221 Remington Fireball, 222 Remington, 223 Remington and 22-250 Remington and I have owned MANY other "LW" Varminters in the past, so my suggestion to you is based on much in the field experience - go with the heavy barrel 204.
Best of luck to you with whichever Rifle you choose - I do know this, though, you WILL be happy with the 204 Ruger cartridge!
Hold into the wind
