Got an update here as well.
I Chronographed my finalized 300 SMK loads on friday and got 2850 fps average with an ES of 12 over the magnetospeed.

After notching a few bear tags was able to shoot at distance. Went straight across 2 canyons to a rock face at 1800 yards. Granted 1800 yards was my best guess on range as I could only range some tree's at approximately the same distance as even on the tripod the Kilo wouldn't hit my intended rock outcrop. Kilo gave me 17.18 MILS elevation, and I ended up needing 17.9 Mils. Considering at this distance, even 50 yards distance changes my drop .9 Mils, I'm going to say the Kilo wasn't at fault here for elevation correction. It was likely off 30 or so yards on the range. Also, even with my 25 MOA Hawkins rings, I ran out of elevation on the LRTS Bushnell at 16.5 Mils so had to hold the remaining 1.4 Mills in the reticle.

Backed it up to 1120 yards and smacked a 5" rock second hit after a first round sighter for wind.

Kilo seems to be matching up perfectly with the 2850 FPS chronographed loads and advertised .381 G7 BC.

Not sure what the heck was up with the 270 Grain ELD-X, I believe their BC's are a bit too generous...

Good info.

The only thing I can think of for mine is that the custom BC’s must be slightly off between the AB iPhone app and AB Kilo software. But when I change it to the G7 BC I have the same problem. I just don’t understand.
