Ordered a 22br barrel from Urbanrifleman this spring when my other barrel was still out 3 months. Got the barrel in about 2 weeks after order and threw it on savage short action and with a SSS stock. Just for kicks and giggles and because I have always wanted to, did load development with Blue Dot with the 53gr Vmax. Most recent testing showing 53gr v max shooting 3 shot groups inside of .2" and a couple 5 shot groups sub .3" at 100 yards. 15.2gr is running at 2920fps in my gun. This has been on virgin brass which has not needed any work other than running through a Redding FL die. I am loving the blue dot loads, about as loud as a 22lr, recoil like a 22mag, can run 30 consecutive shots without much barrel heating, doesn't foul, and cleans easily. I know I can probably improve accuracy a bit running standard powder and some higher bc bullets, but I have having to much fun to switch over for a while. Will see how it does on pdogs this weekend, should be able to shoot without ever having to switch out rifles. I can certainly give a positive review of Urbanrifleman's 224 barrels in a 22BR.
