Sorry I cannot answer about the ballistics calculator either, because all I ever used was a Hornady online drop calculator. The only data I had to input was the caliber, bullet weight in grains, bc, muzzle speed (fps), zero distance and altitude. I didn't bother calculating wind at that time. I planned to hold for it.
I took a 308 Savage from 0.75 MOA at 300 yards to on target at 1,000 the very next shot from a bench rest. All I did was dial my scope to the point between what my bullet drop print out said and what my spotter/coach calculated on his plastic cards. I was about a foot low at first, then came up another full MOA (4 clicks) and I made 10 hits spread across the 1m target but in a straight horizontal line like an equator in the middle of North and South pole. Coach told me that's good, your drop is calculated and precise. Now it's all bout practicing for wind holds and not pushing the muzzle left or right on let off. I just needed to practice from there on out. It was finalized at 29.5 MOA come up from 300 to 1000 IIRC. It's written on a paper and rolled up inside the stock of the gun now. Sad to say I was using rolled up towels as my rests. I was such a noob.
What I had that you have not mentioned was a really good spotter behind me with a 60x scope and a guy in a "pit" below the targets. They communicated on radios. You had the 4 day class, so I'm sure you had something of the sort. But did anyone at the class identify if your misses were all in the same direction or if they were all over the place? Same question for the hits. Were they grouping at all?
FWIW about a month after that (with a proper bipod and a rear squeeze bag) I had my wife out there in the pit and I was practicing again from the bench. After I was happy with my grouping that day I let her sit behind the rifle and I was in the pit. Now, she's never looked through a scope at anything beyond 100 yards, much less shot at it. I can proudly say she was on target the first shot and 9 more times after that one too at 1,000 yards. Grouped about a foot to the right. All I'm saying is, once you have all your equipment dialed in it is a beautiful thing.
