shooting a mossberg sa-20. using a swampfox kingslayer reflex sight. shoots dead center with winchester supremes. I shot a apex 20ga #8 tss im about 3 inches high @40 yards. Figured i would get some advice before i shoot another 10 spot down range. My question is how many of the large hash marks do i lower it per inch. Not familiar with adjustments on this. Advice would be appreciated Thanks
I wouldn't fire another shot. Put the gun in a vise or some other way to hold it in place. Hold it steady. Put the sight on the original POA. Then have someone turn the adjustment screw until your dot is in the center of POI. You can do it yourself, but easier if you have someone turn the adjustment for you while you hold the gun perfectly steady.
I put a pc of blue painters tape on center of my POI(also have one on my POA) so it is easy to get dot moved to the correct mark. With gun on sand bags or in vice, I put screwdriver in adjustment slot. While holding gun still on POA, I do like GW and adjust dot to POI blue tape I put on paper. You can watch the dot go right to mark while turning the dial.
My kingslayer is real touchy. I fired 4-5 shells at 40 getting it real close and still wound up firing one from 20 yards just to confirm. Guesswho has some solid advice to cut down on shells. Provided the first shot was held on the money.

Happy do you remember how many clicks for an inch at 40?
It's a shame that sighting in is a $100 event with tss.
Joey, I'm not gonna let that happen.

For me it was about 3. I didn't have to move mine much at all to see a difference.
Thanks everyone!
When I sighted my 20 gauge, with the Kingslayer I zeroed it at 20 yards with cheaper Federal Grand Slam loads, rather than my TSS loads. Once zeroed at 20 with cheaper loads I then shot a couple TSS at 20 and tweaked the sight to POI while sand bagged, which wasn't much, so couldn't tell you the number of clicks for an inch.
Then I shot a couple TSS at 30 and 40 to verify, I lucked out as the Grand Slam loads were not much different at 20 yards, than the TSS.
Get you one of these, makes sighting in a breeze. You will still need to make minor adjustments but this will put you pretty close right out of the gate.

Cutt, I did that with Winchester Supremes, shooting about 4 inches high with the Apex. I`ll go back to the range and double check before I make adjustments.

This is what I did when sighting my Venom in.
I keep hearing this. I will try it. Thanks!
sight in about 20-25 feet away from target with low brass 8's then check final setting with your chosen loads at 30 or 40. It'll save you lots of money and shoulder thump.
I do exactly what double lung described, I usually just have to shoot one of the loads that I am hunting with. I shoot Federal game loads and Federal TSS. Usually once the game loads are in, I do not have to adjust any further for the TSS.
It's been stated in other threads, but fits here too in case you run into this problem. We had 2 new Burris FF3s that seemed to max out on dot adjustment. It would click and move, but felt like thr screw was in a bind, and the POI was not moving as far as it should. We ended up putting the guns in a sight vise and moving the dot the opposite direction really far, then again in the right direction past where it needed to go, and then back to the correct spot. That freed up whatever was in a bind and the POI and POA became the same as expected. It happened for L/R on one and U/D on the other, but same solution fixed then both. If you get a new or used red dot of any brand, I highly recommend moving your dot to the extents in all directions and then count the clicks from on end to the other, then move it back half the clicks to reset and start from the center of the adjustment range.
This has got me in the ballpark quick:

Take a cheap target load at 10 yards or so to fine tune, then I'll take a shot at 40 with TSS, make small adjustment if needed, and then take 1 more shot at 40 with TSS to confirm. I might use 3 shells of TSS (or 4 if it's being stubborn) to zero in at 40. Now testing out multiple different chokes is where things can get pricey for me.
Now with my Kingslayer I can't remember offhand how many clicks for 1". Maybe 4 or so, but I'd be guessing from last year.

Just sighted in a new choke and FF3 today. Sighted in Number 8's at 12 yards then moved to 20 with a TSS. That was perfect so I shot one at 40 and that was also perfect.

I`m happy for you. Being from NY also #8 is small as we can go. I will try again next week hopefully. I`m using Apex 20ga 3inch 1 5/8 0z tss. Carlson .575 choke. Pattern does not seem to be dense as I like. My buddy thought it was good though. I`ll get there thanks.
How much a click moves POI is simple math. Most, but not all, are 1 inch at 100 yards. Fifty yards, half an inch, 25 yards a quarter inch.
That is correct isn't it? Long time since I was in school. LOL

Sight it in with cheap lead loads, and check with TSS when finished.
