I'm still looking for the "perfect load" for that 22-250 "striker" pistol. So far I have tried pairing the Sierra 52-grain HPBT match bullet with the old DuPont INR-3031 and the IMR-4064 powder. Two weeks ago, I thought that I was getting a fairly close group using 31.5 grains of 3031 so I tried it again last week with loads of 31.4, 31.5, 31.6 and 31.7 grains but I couldn't see any major difference between them. Yesterday I tried the 52-grain HPBT bullet with 32.7, 33.0, 33.3, 33.6, 33.9 and 34.2 grains of IMR-4064 powder. I was getting fairly good groups with the 33.0 and 34.2 grain loads. I had removed the scope and reinstalled it with an anti-cant device prior to going out to the range so the impact at 100 yards had shifted to the left about 2 1/2 inches. There was also a breeze between 7 and 4 mph coming from about 285 degrees from the target that might explain the horizontal strings. I'll need to do more testing using new powder (the stuff I have been using is from factory sealed cans that are around 10 years old) on a calm day.

Last week I discovered that running patches soaked with "Kroil" through a hot barrel using a nylon cleaning jag is not a good idea. The Kroil softened that jag to the point that it was bent at a 45 degree angle after exiting the barrel. I got a new 24-inch Dewey rod with a brass jag in on Thursday that works like a dream. I'll have to clean both the pistol and a Sharps rifle today.
