I definitely had "good enough" with my preferred factory loads, especially the Federal Premium Gold Medal I ran in my .308 on the channel. It consistently performed sub-0.4 MOA, and on one occasion, I filmed a 0.03 MOA cold-bore hit at 481 yards. That's a 1/8" deviation from my point of aim. I discussed it here: http://bit.ly/prc-009Your set up and dies may not behave like the internet says. Measure and adapt. Find an experienced competitor so you have someone local to ask.
Many of the YouTube people are very accomplished shooters. It way take some time to benefit from all their wisdom. It takes longer to make great ammo and at times I should have settled for shooting more ammo that was "good enough".
As a new handloader, my motivation is maximum precision and consistency. I want to learn how to get the very best results possible. It took almost 30 years of shooting, but I'm finally done with match factory loads!
