I love shooting at rock lake!Im extremely pleased with my rough RSS. Trijicon accupoint 3-9 and 24.5grains of tac at mag length had an SD of 3fps over 3 rounds so I stopped there to not ruin my hopes. Was getting consistent hits out over 700 before my scope runs out of elevation. I dialed the accupoint for 70 rounds from bottomed out to 24moa above my zero and never felt like it wasn’t tracking correctly. Not enough for a novice like me to notice. 2833fps was my trued velocity from StrelokPro. Got DA using the same aviation chart Form has posted previously. Between strelok and a rough understanding of the altitude I was within the ballpark of a kestrel every time. I need a small thermometer on my pack or something.
Things I would change; 1. Sacrifice the weight of the scope for the tenmile FFP and a zero stop. I have my zero marked in number of revs from the bottom but it’s a hassle to do that repeatedly. 2. Try the tikka vertical grip. I might not like it for N.Idaho hunting situations. 3. I want a suppressor.

While I'm not going down the Tikka 223 path, I'm going with a 22" 7.5tw 22gt 120 freebore chamber to launch my 77tmk. I think 3100mv should be a balance to keep over expansion down at shots under 200y but keep my range out to 700y with 1750mv for reliable performance.
