Re: .204 ruger-maximum range?
2brothers, can you explain the extra powder capacity, smaller bore size, and significantly higher velocities to have the same barrel life as the 223? I am coming up on 1000 rounds down mine, and I expect to see 2000 without much trouble, not over 2500 though.
I highly doubt I'll see 4000 in the 204, but then again, I know of several hide members who have said 4500-5000 with a 300 WM was where they started going MOA+ with it.
I would not choose the 204 for anything, even steel shooting beyond 800y. The bullets are certainly much less expensive for it compared to a similar quality 30 cal. The 40gr bullet in 20 don't see much beyond a .33 G1 BC, so the 3850 fps muzzle velocity degrades rather rapidly.
To the original question, the 300 WM is going to reach much longer distances. The 204 will be cheaper to shoot, neither are known for great barrel life when compared to something like a 308 or even a 30-06.
Taking that in mind, I generally suggest a 308 or 223 for non-reloaders that are starting out because quality ammo is available from several sources in both calibers. For reloaders I suggest the 30-06 or something based on that case, like the 280 or for short action something based from the 308 case like 243, 260, 7mm-08. The 30-06 will outrun a 308 by several hundred yards, it has the case capacity to shoot the 210gr class bullets in the upper 27's through the 2800's depending upon barrel length. Brass is abundant, it works well with about a dozen different rifle powders, and off the shelf ammo that's well suited to every game animal on the continent is available with relative ease.
