Ok - I checked Nosler reloading #5. And found my 200 yard target. For 415 BC Nosler reads 6.8 inches high for a 300 yard zero, which agrees closely with my previous stated 8"(actual target just over 7) allowing for operator error, field and brain. 8.2 low at 400, 17.6 at 500, not yet field shot..
Since my field shooting agrees with Nosler, I'm just gonna ignore that other ballistic chart until reason otherwise.
You can't believe everything you read... Learned that a long time ago....
