gsmopar Posted December 27, 2014 Report Share Posted December 27, 2014 While shopping for optics for my new bolt gun, I stumbled across Hawke Optics. Their scopes have several features that I really like (Locking focus, windage, and elevation), but I'm not famaliar with the Parallax adjustment. Amazon black Friday deals were too good to pass up, and I ended up with this bad boy (http://www.hawkeoptics.com/hawke-sidewinder-30-sf-8-32x56-20x-mil-dot.html). Playing with the side focus parallax seems pretty accurate to the 200 yards that I've tested around the house. Does anyone else have experience with these type of scopes?

planeflyer21 Posted December 27, 2014 Report Share Posted December 27, 2014 Are you saying you aren't familiar with parallax adjustment in general or just the mongo-jumbo wheel parallax adjustment? Quote Link to comment Share on other sites More sharing options...
Zebra644 Posted December 27, 2014 Report Share Posted December 27, 2014 We could probably give a class and references as most of us own decent glass. But what specifically are you wanting to know? Quote Link to comment Share on other sites More sharing options...
mrmackc Posted December 27, 2014 Report Share Posted December 27, 2014 Did you read the single one star review on Amazon? Quote Link to comment Share on other sites More sharing options...
blue109 Posted December 27, 2014 Report Share Posted December 27, 2014 that's a pretty impressive focus knob! might have to add a counterweight to the right side of the rifle. Quote Link to comment Share on other sites More sharing options...
gsmopar Posted December 28, 2014 Author Report Share Posted December 28, 2014 (edited) Is the fine adjustment for the parllax meant to measure distance (range finding)? The scope came with 2 knobs. The large one show has finer adjustment from 10 yards - infinity. I haven't been to the range yet, but I used the Maricopa County Assesor site to mark off 100, 200, and 250 yard objects near my house. Using the parllax to focus the objects and referencing the distance on the knob; they appear to align. Yes, I read all the Amazon reviews. Midway also has some reviews on Hawke, but not this model. Youtube has a few videos as well, but most are European. The Black Friday/Cyber Monday (don't remember which) marked the scope down over $200. If it sucks, I'll return it. My first impressions are positive (nicer than the Burris on my LR308). On a side note, the free software on their website is pretty neat. Worth a look even if you don't like the scopes.

Zebra644 Posted December 28, 2014 Report Share Posted December 28, 2014 (edited) Parallax is essentially an optical illusion. Parallax presents itself as the apparent movement of the reticle, in relation to the target, when your eye moves off center of the sight picture (exit pupil) or in more extreme cases it appears as an out of focus image. It indicates that the scope is either out of focus or more specifically the image of the target is not occurring on the same focal plane as the reticle. Maximum parallax occurs when your eye is at the very edge of the sight picture (exit pupil). Even when parallax is adjusted for a designated distance, there is an inadvertent error at other distances. Most brands of scopes that do not have a parallax adjustment are pre-set at the factory to be parallax free at or around 100 yards; rim fire and shotgun scopes are set at or around 50 yards. Most scopes of 11x or more have a parallax adjustment because parallax worsens at higher magnifications. Generally speaking parallax adjustment is not required for hunting situations and is primarily a feature used and desired by target shooters. A 4x hunting scope focused for 150 yards has a maximum error of only 8/10ths of an inch at 500 yards. At short distances, the parallax effect does not affect accuracy. Using the same 4x scope at 100 yards, the maximum error is less than 2/10ths of an inch. It is also good to remember that, as long you are sighting straight through the middle of the scope, or close to it, parallax will have virtually no effect on accuracy in a hunting situation. www.opticstalk.com/what-exactly-is-parallax-anyway_topic5026.html Edited December 28, 2014 by Zebra644 Quote Link to comment Share on other sites More sharing options...
MikedaddyH Posted December 28, 2014 Report Share Posted December 28, 2014 (edited) I have one on My 300WSM AR. Its a pretty good scope,adjustments are fine and accurate. Tom has shot it,Jon and others.;-) Edited December 28, 2014 by MikedaddyH Quote Link to comment Share on other sites More sharing options...
unforgiven Posted December 28, 2014 Report Share Posted December 28, 2014 Good explanation brother Zebra,the Nikon 4X12 has this adjustment with the yards next to selection for reference. Quote Link to comment Share on other sites More sharing options...
gsmopar Posted December 28, 2014 Author Report Share Posted December 28, 2014 Thanks guys! I'll likely hit the range next week (if I don't try to sneak in 1 more Dove hunting trip). Quote Link to comment Share on other sites More sharing options...
Zebra644 Posted December 28, 2014 Report Share Posted December 28, 2014 I forgot to mention that the numbers on your parallax wheel lol are yardage indicators to set the adjustment. So if your shooting at 50 yds. adjust the parallax knob / wheel to 50 yds and so on to minimize parallax. Quote Link to comment Share on other sites More sharing options...
98Z5V Posted December 29, 2014 Report Share Posted December 29, 2014 (edited) The speedometer explanation goes a long way. Easy explanation of what parallax is, but doesn't necessarily explain how it impacts shooting. Zebra knocked that one outta the park already. The Speedometer. You're driving, and holding the Speedo needle straight-up on 60mph. You can see that easily. If your passenger looks over from the passenger seat, it will look like the needle is below 60. That's parallax. That's also why your wife always gets so pissed when you're driving. <lmao> Edited December 29, 2014 by 98Z5V Quote Link to comment Share on other sites More sharing options...
