The RMR 69 3GH is decent for the price, about 1 MOA at 100 yards in my rifles. The 69 SMK shoots much tighter.Have you looked into the RMR 69gr bullet they make in house? It's my go to for cheap and accurate, especially in a gas gun. They seem to shoot very closely to a 69 SMK. I use it in 223 ar and bolt, 224 Valkyrie and 22-250. And I'll never look down on the 75gr Hornady for bulk steel days as well.
