I recently installed a 26" barrel on one of my 204s and have some questions. This barrel does not allow me to shoot as high of pressure ie powder charge as my stock 22" rifle. As a result the velocity is also not as high. For example I can load 24.7 grains of h4198 in my 22 and get 3780. With the 26 I max out at 23.5 and 3700. I am using PTG hs guages and tried to set hs as close to same as the stock rifle as possible. Using the go Guage I run it to where I just get a little resistance, similar to the stock rifle. If run a piece of tape on the base if the Guage the bolt won't close. Ok so is this a problem with not enough hs? Should I set the barrel a little looser? I just don't get it. I expected 100 fps faster at same powder levels but can't get there. Another weird deal is factory Hornady ammo will in fact to about 100 faster. Accuracy is fine with my hand loads. Shooting around .25 or less moa.
