CZ455 Varmint Tacticool
« on: March 05, 2018, 04:07:52 PM »
not sure if i'm doing this right....i suppose i'll find out soon enough
recently purchased CZ 455 V T should receive delivery by Thursday , and was wondering what would be the best to zero it out at ...25, 50 ,75, 100....been doing a little reading online still not sure....i saw this quoted ""Interestingly, 75 yards is the distance Jack O'Conner, the Dean of American gun writers, suggested decades ago for zeroing a scoped .22 LR hunting rifle."if this is what the opinion here would be then i'll shoot the 75..............anyhow this is my first time on one of these boards, thanks

One element to consider, which you may have already, is the trajectory of .22LR ...if you zero at 100yds you'll be 2.75" high at 50yds and 2.4" at 75yds (using 40gr loads) - you might consider a 75yd zero.

With a 75yd zero, the amount of error is less than a 100yd zero (the bullet doesn't drop 1.5 inches below the line of sight until it reaches something like 85-90 yards). As a general rule, beyond the 90 yard mark the bullet's trajectory drops so steeply that it would be difficult to maintain accuracy (may not be exact for your rifle and ammunition at your altitude).

I set my zero @50 yards and printed off some small ballistic charts I can reference on the fly based off the bullet info I enter into a ballistics calculator app. It's dead on for me. If it says 7 Moa of adjustment to hit at 100 yards I'll turn the scope up 7 moa and it hits where I put the cross hairs.
