I use ballistic turrets on all three scopes, .243, 6.5CM and .308. I zero them at either 50 or 40 yards in order to exploit the PB for the round I'm using. I use a ballistic calc to determine what the round should be doing at various ranges, then go and test them to be certain. For example, a 58 grain foxing round in the .243, zeroed at 50 yards prints 1.2" high at 100, 1.5" high at 150, back on zero at around 200 then drops to 0.7 low at 225, and a full 2" at 250. This tells me that a centre mass body shot on a fox is good from 25 to 225 yards. Most of my foxing is done at night under a lamp where it isn't practical to range them with a laser, but the turret comes into its own for daytime long range varminting, where I have a sniper tape patch on the scope with the elevation required written out in moa out to 600 yards. (9.25 moa) These have been tested by shooting plates at 50 yrd intervals, and successful hits at intermediate distances are written in a notebook which lives in the drag bag. SO a 418 yard bunny was dispatched with 3.75 moa elevation and the result noted for next time I encounter one at that range.
I use the same principle for the deer rifles, with a close zero to exploit the curve. The .308 loaded with 150 gr Nosler BT at 2600 fps (slow but very, very smooth and accurate) is zeroed at 40. It rises to 1.2" at 100, and back on zero at 160, dropping to 2" low at 200. That point blank means point of aim kill shots on deer at all decent stalking ranges, woodland and hill. I haven't yet had time to go out and test drops with the plates, but my lad has confirmed kills on foxes out to 200 and a hill stag at 175. Woodland roe are simply point and shoot.
