Ballistics calculators for airguns with MRAD scopes

[Billinoregon]

So, Strelok is banned, Hector pulled the plug, Chairgun is gone and the American Airguns calculator does not seem to compute MRADs.
I am looking for a simple trajectory calculator for my HW97K, .177, H&N Baracuda FT 9.57, BC of .015, at 800 fps, scope height 1.595, 10 to 55 yards with 25-yard zero. Scope is Element Helix 6-24, SFP. I'm kinda clueless about this stuff, and in over my old baby boomer head.
Any advice?

i don't know if this will help, but nothing beats dope anyway.

You can still get ChairGun elite + in the App Store. It work’s identical to strelok.

Wish they had a elite version on Android.. the pro is ok but lacks a lot of stuff

Sounds like you are trying to map out your dope sheet for Hunter Field Target.
I think you already know those programs are going to give you an approximation.
Ultimately, you are going have to shoot paper to verify those numbers. Keeping in mind how you rest the rifle is going to affect your POI. Especially in a FT position and shooting springers.

Since you'll be shooting paper anyways...why not skip the ballistic program predictions and just shoot paper.

With a graph/plot dope method, minimally, all you need to verify your dope are 5 distances. you need to shoot exactly at 10 and 55 yards. Then approximately at 15, 25, 40. I then extrapolate my drops at other distances from the graph.

In my experience constructing a dope sheet for my TX 200 for WFTF piston, that should give you enough information to start. I started shooting by clicking my elevation turrets. Lately, I've been switching to shooting with mil-hash. I find more psychological comfort in shooting mil-hash (similar to hunter FT) as I'm not changing any vertical turret adjustments. (don't get me started on click lags...that's a whole other topic)

Thanks JP. Taking your counsel very seriously.

I would just sketch out your reticle holdovers on a small notebook (waterproof paper highly recommended).
Example picture attached.
Or plastic laminate ordinary paper.
Just sight in and record your hold overs.

I have a small sketch like this taped onto my elevation turret cap facing me. Waterproof paper of course.

+1 on the "sketch the reticle" method.
There's probably a better way out there, but for now this works for me too.

I actually mark my holds on my focus wheel. Instead of yardages and a cut sheet, I just have it marked +1, +2 +3.5 etc, so when I focus, it tells me my holdover with no extra paper needed. FWIW.

PM me with a cel # will text you a print out as requested .. here ya go

Ideal ZR is 22 y and you have 9 & 56 y for those just past and just under numbers too work with.
