[QUOTE="7070yshot, post: 2074597, member: 114427"] First, shoot larger strings. 3 shot strings are not enough. 5, 10, even 20 gives a true dispersion rate. secondly, if this is a hunting rifle with the typical factory gun and light barrel, I would not expect more. Getting into trued and custom guns you can have that expectation. If you are shooting 1 MOA you are fine. Bryan Litz cover this in several books as do others. Everyone wants the 1/2 MOA or 1/4 MOA Gun but maintaining that level of consistency from a factory gun is not realist IMO. They are good and can be very close to that given modern manufacturing but 3/4 to 1.25 MOA is fantastic for hunting within the calibers PBR. I know some will criticize this and personal stories about this/than gun and my friends etc story but the reality is it’s not true. All that being said you can improve a factory barrel by using the Tubb Final Finish bullets. This is called fire lapping and it works. Since you are a reloader this should be no problem. lastly on many occasions I have found loads that are that 3/4 to 1.5 in group that was significantly improved by adjusting neck tension and then primer depth. All these things take time of course so it just depends on how much that extra 1/2 in is worth. [/QUOTE]
