Watching prairie dogs flip up in the air, turn inside out and rain pieces has always brought a smile to my face, especially after nearly breaking my ankle so many times in the pot holes they leave everywhere. We have a nearly endless supply of them here in Wyoming and ranges of well over 250 yards are very common. The 204 Ruger has a muzzle velocity of around 4,000 feet per second [give or take a hundred] - The little bullets are about the same weight as an average .22 round but they are smaller and so much faster than the 1100 feet per second velocity of a .22. If the wind is blowing, this is not your winning combo but it has very little kick and it does not bark too loud.

I originally used H335 and had great luck with accuracy but H335 became very difficult to get so I worked up a load for W748 - I did also get an extra 100 ft/sec over the H335 load for the 40gr bullet.

Here are (7) 5 shot groups

Like I was mentioning, the best accuracy is not always the best consistency as shown by the table above and the targets below

I ultimately did a compromise between group 4 and group 5 - this is where both accuracy and consistency was the best. Any little breeze influences this round so there is a bit of guess on the accuracy part but the standard deviation is most acceptable with a charge weight of 27.8gr
