I recently purchased a SWFA SS-HD 5-20x50 (MRAD) FFP scope
and was getting ready to install it on my rifle. Prior to doing so I was
running the windage and elevation stops to get the cross-hairs centered and
now I have a question. |

The SS scopes typically have a greater range of vertical adjustment. All the ones I had or used have adjustment ranges in the ballpark of what you describe. It is not a flaw, it is a feature... I would be glad of it.

They normally have plenty of windage. I'm sure SWFA will swap it out if you think you'll need it ever. Most of the time they are conservative on estimates. They probably tell the factory that anything less than 30 is rejected and somehow the windage on that one fell through. SO they have a minimum standard but no maximum, hence why they aren't all set at 30. I believe mine is around 39 in elevation but would have to double check.

They are basically garunteed to have atleast 30 mils of travel. 40 Mils is not unusual or a bad thing. In fact it is amazing it has that much in a 30mm tube. The Bushnell HDMR can't even pull that off with a 34mm tube. The windage and elevation are offset like that intentionally. 20 Mils of windage should be more than enough. If it isn't you have bigger problems. 20 Mils is roughly 6 feet of adjustment at 100 yards, 3 feet each way and it just gets bigger the farther out you go. If you need more than 3 feet to zero a rifle at 100 yards it is either drilled incorrectly or there is an issue with the mounts. Just to give an example
at 500 yards you would have roughly 15 FEET of windage travel both ways, 30 total.

Chris - thanks for the response. Like I mentioned in my post, I don't even plan on using the windage knob - any adjustments that I need will be made using the windage reticle marks. Thanks for the extra adjustments in the elevation though - I plan on zeroing it in at 200 yards, and with that much vertical adjustment I should be good to go with my .308 past 1000 yards. Thanks again!
