[QUOTE="kraky2, post: 252189, member: 3532"] There are all kinds of feelings about what bullet runnout does to the accuracy of a rifle. I would submit the following and I'm sure I will be corrected quickly.... For the average hunting rifle for out to 300/400 yds shooting: Match grade is under .003" total runnout. average ammo under .005" runnout. getting bad .005-.007 runnout. bad over .007" runnout. For the long range and benchrest crowd. Match grade is under .001" runnout. Average is under .002" runnout. Getting bad is .002-.0035 bad runnout .0035 and over. Also remember that the average hunting rifle has a chamber that is much looser than a match grade rifle and even .001" runout will probably not get you perfectly aligned with the bore of your barrel. The match grade rifles are aligned perfectly and have chambers that do hold perfect ammo in near perfect alignment. I would also venture to say that a high quality match grade rifle shooting .006" runnout ammo will probably outshoot a decent factory rifle shooting .001" runnnout any day of the week. These are really vague statements and based on my admittedly biased opinions! [/QUOTE]
