Hello again, I went to Hornady's g1/g7 calculator which I've used for years on Hornday bullets with reasonable accuracy. Last year I was having issues with it giving me weird data for a manually inputed norma load so I decided to run my new handload through it and geo ballistics. Geo ballistics says I hit 2000fps at ~350yards. Hornady says ~475yards. a random online solver said ~400 yards. Data in the pictures if you're interested in running it for yourself. Obviously I need to get out there and shoot to see what my drop and realistic data is. But, they're all so far apart it makes me wonder.......

I tried running it in geo and online with their native libraries to get the numbers above. I then manually over rode them to make them match the hornady pictured. 8459.jpg

I switched to AB quantum last year after the Hornady app was being a huge pain to use. I have no issues using the AB app. I’ve only shot out to 500 but it’s also about the limit of my effective hunting distance, and my holds are accurate.
