burris fastfire III zero in question

dog229 · Mar 28, 2015

Dog229 Here,
First time using a red dot and on a revolver (617 10 shot) what is the correct way to zero in the red dot from the bench top or shooting in at range. And what yardage to zero from to be dead on at 20 to 40 yards.
I am using the Allchin mount that i got this week ( Really nice guy, Great mount to have)
Thanks!

I just did the same set up on one of my 617's and I just shot mine off hand at 15yds Haven't shot it at 25yds yet but, it should be real close.
One thing to check is make sure your FF III is square on top with the mount. Hard to get the windage correct if its off bit.

I have always had good luck setting my 6 inch revolvers at 25yds shooting 158gr magnum loads.that will keep you on a full size torso target from 5yds out to 75 yds..38 loads have a little less climb at 25yds but close enough for the same zero.I am getting ready to order the same mount and a fast fire 2 to outfit my 586.I turn 40 next month and my focus is starting to fatigue my eyes with iron sites.can you post some pics of your revolver with the red dot mounted?

dog229,
If you can get the FF III instead you will be better off. The battery goes in from the top instead of removing it from mount to install the battery underneath and the III comes with a auto brightness feature so you are not fooling with the adj. knob. If you purchase the mount i went with the black for it matches the red dot black perfect on the Burris. Allchin said the silver doesn't
look right on stainless if you have stainless!

Just a hint, if you are going to be consistently using outdoors, get the 8 MOA dot, and not the 3 MOA dot. For slow bullseye shooting you can get by with the 3 MOA, but any kind of action shooting you will spend too much time trying to find the dot.

Zero the gun for the range you normally shoot. For 20 and 40 yards, I'd probably zero at 30 and knowing I'd be a little off on each distance, but learn to hold over/under if you have small targets. On any kind of IPSC type target the "X" ring is large enough you could hold center and stay within it.

That is excellent info on Fast fire redot. thanks guys.Love the way these micro dot sites look with the allchin Base.nice and low.do you guys have any ideas on holsters that will work with that much hardware on top?

With this set up only open front competition holsters. You wouldn't want to attempt to carry it in one of those for any distance or time, they are made for fast drawing only.

Dave,

I have a 625 in 45acp with an RMR mounted similarly to the one that H Richard posted. I fabricated a custom mount, but my forward position is very close.

It is easy to modify a kydex or combo kydex holster to fit the gun and sight, and be completely safe for any kind of carry. the top/front of the standard holster can be easily cut with a dremel type tool to clearance for the sight. It is best to have one that is tightly molded around the cylinder, and fit to the bottom of the trigger guard. Also the fit of the kydex around the barrel and lug can really add a ton of support fore and aft.

I have fiddled with leather holsters, and the removal of the material really makes them weak. I do most of my own leather work, and I may try and do something with a strap that snaps over the sight. Right now I have two kydex modified holsters that work great. I do hate kydex, but I very much like the dots.

RMR on a .45 Colt. Zeroed for 75 yards. Have to hold about 4inches low at 25, it's within an inch or two at 50, and about 3" low at 100. All shot standing as that's what the match rules specify!:
