[QUOTE="Ekupp, post: 2870113, member: 104593"] The rifle has been shipped to rifle manufacturer even though there was a suggestion to talk to the barrel company from the rifle company. Couldn't waste any more time and ammo trying to sort it out. To answer your questions ammo box stated velocity is 3000 fps in 24" barrel. I have a 22" barrel getting 2810 fps ave for 3 shot groups as measured with a magnetospeed. Other barrels from this barrel company perform very well and require little break in. I would expect near 2950 after break in but initially 2875 at the worst. Ammo could also be the issue. After cleaning to metal first 3 shot group is .75 moa without working at it. 2nd 3 shot group will have a flier. Any further groups are random and 2-3 inches. I repeated this 3x meaning after I got to 2 moa + accuracy I cleaned to bare metal. I did some swabbing between groups for the first 10 shots accuracy still dropped but returned after cleaning to bare metal (copper and carbon eliminated per bore scope). [/QUOTE]
