I've only hunted for 50 plus years so here's my 2 cents worth. I have an A bolt also with a 4.5 to 14 Leo on it. Seems to work good for finding game in all magnifications. But rifle fit is important. I still do not like dial ups and I have several for varmints where a miss is OK, just a piss me off, not a lost trophy. I have the one with the hold over crosshairs and once the sight-in is checked. The scope does not move for the season. I have at one time or another sent all major brands(I have not owned them all) back to the factory for cleaning and rebuild for jumpy turret movement. My A bolt will go out to over 600 yards with the hold over cross hairs with a sight in at 200 yards, so I have a dead on hold from zero to 240 before I even think. OH I(really my son, as we both played with loads trying to find the best) found a load for the 300WM that holds 1" at 200 yards and it has not been feed anything else for a lot of years.
