I just buy the factory rounds, I have them for my AR, scout 308, and my 300win. have never had any issues. I was messing around with the 150 grain 308 and 165grain 300win and shot 500 and 685 yds with the factory loads and had groupings of 5" diameter. I will get into reloading down the line here this years since the ammo shortage. My last pig didnt like em very much!!!
