Sig Sauer ASP20

That's sweet. Gonna resight sig for 28m (if the wind ever stops)
Turns out (according to gun chair)
With my weight pellet .67gm and volicity 897fps, it will give me a lot better hold over readings on mildots.
.5=37m,1=44m,1.5=50m,2=55m, 2.5=60m,3=65m, 3.5=69m,4=73m,4.5=77m,5=81m
Which is awsome for the 50m to 65m range, which is where I need to be for hunting hare here.
With 20m and 25m just above the windage line.
Lot easier to rember than last sighted zero.

Totally. I think further back up I have the two differnt flight paths in mildots between AA and exact done as you do.
However gunchair with info in it will put me right in the ball park, and as with all things fine tuning will be done manually.
Its the same with mildot ranging, have distances by mildots from calculations but at end of day, stapling a hares head to a post (eeeeewww) and setting it at distances allowed me to measure and record how I see it through the scope.
I agree with totally, but gunchair has given me the range to work in and I can retune the data from there.
I also found that acurate scope height for gun chair is a vital bit of info that improved its prediction when I used the vernier to measure it, once I'm Sighted in I'll throw the chrono up by the targets and work out the true ballistic coefficient for the pellets, which will further fine tune the app.

If any of you guys/gals are keen to take your favorite pellet/s for the sig
and do a bit of real life drop measuring, post it, it would be rather interesting to see the flight chararistics of them, then compare them to others results and see if there's definite flight paths veriations that ring true for a certain pellet.
Thinking AA, exact, barracuda be good starting point as seems to be the most recommended by users here.
Prob need the zero for your distance you are set at too. If you could provide volicity that be a bonus.
Once this weather stops!

Yep I ended up at 3.94cm (1.55 inch) for scope height. With that said, I had to measure from bore center to top of barrel, then as the barrel is a tad higher than the piston cylinder, measure how much higher that was and subtract it from the first measurement.
After that measure from top of piston cylinder (receiver?) to center of scope.
Very nearly just put 4cm in data but every mil affects the out come.
Hawk don't do updates for chairgun any more so be aware of that. You cant update pellet database and stuff online and if its not in the list will have to put it in manually. Not a biggie. I'm not recommending it either, it just happens to be what I am using as it was designed for air guns.
In order to keep it all on a level footing, what about we do 15m out to 50m at 5m intervals.
Aiming at bulls and recording the mildot drop and/or cm/inch drop.
I'm using meters as most scopes will be mildot and not moa (although for some weird reason my hawk airmax is mildot on retical and moa for adjustment. There is a a way of setting up to correct that if anyone is interested I'll find the video and post it)
15m/16.4yd
20m/21.87yd
25m/27.34yd
30m/32.81yd
35m/38.28yd
40m/43.74yd
45m/49.21yd
50m/54.68yd

Just a bit of useless information. The stock on the Sig Asp20 was patterned after the SIG Sauer SSG 3000 sniper rifle
