Hornady’s 88 gr Eld-M load is money in my gun, but I could not reproduce it with hand loading. I found a great load using Berger 75 vlds, but they’ve been iffy to source. In my limited testing, these are the only 2 loads that were really good. So, yeah, maybe the 22 arc is a bit sensitive. All of my loading of the 22lr has been for a gas gun, with Hornady brass and cfe223, for what it is worth.
