Just upgraded Strelok to Strelok Pro. Wow!

[Vodoun daVinci]

For $12 it is awesome. I was concerned when I had the basic/free Strelok because my DOPE simply did not match the information I was getting with Strelok. Way off. Upgraded to Strelok Pro and now my DOPE matches the calculations from Strelok to the Nth degree.

Plus I get all those extra goodies like Corialis effect and Spin Drift and virtually every reticle known to human kind.

Impressed...very impressed. Well worth the $ and then some!

Yo, that’s dope.

[Spblademaker]

Sorry. Play on words. Upgraded last year. Use it for 22LR ballistics.

 

[ForgeValley]

I like it a lot. He's constantly tweaking it and updating, way more than some of the other ballistics apps I have. Cartridge database is huge.

I'm a big fan of Strelok Pro (I never tried the lower versions... went straight to "Pro").

But, I've also played with Ballistics ARC and Hornady 4DOF. I find them cumbersome and non-intuitive.

Strelok is very user-friendly / intuitive.

 

[Sogan]

What changed in the pro version to allow your dope to match better? A truing function?

 

[clcustom1911]

Been using Strelok Pro for at least 2 years. Very intuitive. The AB in my Kestrel usually agrees within 0.1mil (3.6" @ 1000yards) and that's plenty fine for me (read: as long as I "ding" my empty keg at 1000, I'm happy).

4DOF is new to me, playing with it and learning it's quirks... like not having any data at all for any other bullet aside from Hornady... which led me to purchase some 147 ELD-M's for testing.... Marketing works LOL... but so does 41.6g of H4350 in Prime brass

Pro allows for both velocity and BC truing, zero offset, Bluetooth pairing with assorted weather meters, and some other magic I cant remember right now. I really like it because it's a very straightforward, intuitive user interface.

 

[Mordamer]

I have both versions of Strelok and I had great luck with Strelok free version before upgrading to Strelok Pro. However, I found that Strelok free version needs a much different B.C. value than Pro to get the same data. I held all other variables in the calculators equal and a bullet in the free version would true B.C. to .610 G1 while Strelok Pro trued out to .583 G1. I found that both can be made to give accurate dope out to transonic distances, but the Pro version takes much less tweaking. I simply enter the G7 B.C. and velocity and I'm usually within a tenth mil out to 1,000 with most cartridges.

As stated upstream, Strelok Pro seems to have more/finer significant bits in the calculation. Spin Drift, Coriolis Effect, etc. and seems to use velocity, weather, and B.C. better. All I know is that I was frustrated to some degree with the basic Strelok because no matter how carefully I input my data it was always off from what DOPE I actually accumulated by quite a bit.

I shot a couple hundred rounds of factory Hornady 147 gr. ELD-Match last Spring/Summer in varying conditions from low humidity and temps to 90% humidity and temps near 100F and ranges out to 300 yards and the DOPE I gathered was not very close to the calculated drop and drift. I was using the data for B.C., velocity, etc from Hornady given a 24" barrel and chalked the difference up to variations in the actual data as fired from my gun.

Inputting the same data into Strelok Pro gives me a calculation that is dead nuts ( within 0.125 MOA) on my accumulated DOPE from 50 - 300 yards. So now I trust it to give me calculations further out for which I do not yet have DOPE and confidence that it is pretty damn close.

Really impressed with Strelok Pro. I have used apps from Hornady and others but they were not intuitive nor any more accurate for me.

For the non-Hornady bullets I reload with (69 SMK, 168 SMK, 175 SMK) Strelok Pro is a great solver and what I use. I also use it to pull altitude and pressure to put in to 4DOF.

 

[rjanw01]

is the list of reticles more extensive in the pro version vs. the free? I just downloaded the free version to snoop around as I am new to this. Was looking for the Athlon Ares btr reticle and it does not show in the free version.

 

[PusherX11]

You can also email Igor if your reticle is not in the list and he will add it, and reply back to you. Hopefully he will be adding ZCO to the app sometime soon.

 

[Vodoun daVinci]

I bought Strelok Pro to get the exact reticle for my Athlon Argos BTR and did a fairly thorough research of how many and what reticles were supported. Didn;t find many that were not present and as already stated, if you send Dude an email of what you want you'll probably get it.

Still really impressed with Strelok Pro.

[VP47PPC]

Going on one year of using for PRS, NRL 22 and small bore silhouette . The bullet data base is great and the reticle graphic is useful.

 

[cperazza]

I have been using Strelok for 6 years and Strelok Pro for the last 3 years with great results. Developer is always updating and making things better.

They use to have the Horus Tremor reticles.
"Horus reticles were removed according new patent owner (HVRT Corp.) request.".

It would be nice to for the Horus reticles to be included again, specially since it will help both the app and Horus market.

 

[pugnado]

Horus vigorously defends their patents and thus it is unlikely to see it in Strelok Pro anytime again soon.
Look at the price difference between Horus & Non Horus reticles of the same scope designs. That's how much royalty they get.

What Igor should do is let us upload our own reticle images and then define the center point and the 1 MIL/MOA mark on them
at a particular magnification.

I would then upload a custom design of my own, for my own personal use, that looks like this:

 

[BLKWLFK9]

I've used virtually every engine out there and I keep finding myself always coming back to strelok pro. I seem to true is way faster and more accurately than every other one. Even trasol which I like also.

 

[pugnado]

I shoot mainly 6.5 Creedmoor and my current 147g ELD-M loads reach 2500 fps and stay supersonic out to about 1200 yards.

So I have been comparing the various ballistic calculators out to that distance by putting in all of the same variables in each, and making things easy for the calculators by setting wind to 0, earth effects off, spin drift off, zero conditions the same as shooting conditions and so on. The 147g ELD-M lists three different G7 BC's for each velocity band so I used those wherever programs allowed. Obviously, 4DOF doesn't use BC.

Settings were: 2500 fps muzzle velocity, scope over bore 2.5", zero 100 yards, alt 0 ft, temp 59f, humidity 50%, pressure 29.92, windspeed/direction 0 and 0.

(My reticle and turrets are in MRADs.)

Earth Effects and Spin Drift Off:

Strelok Pro: U14.4, L0.0
4DOF: U14.48,L0.23 (No way to shut off spin drift in 4DOF. Use table and subtract spin drift, works out to 0.0.)
4DOF (BC-G7): U13.73,L0.23 (Again, can't shut off spin drift. Doesn't use a variable G7 BC, might be working off the high value.)
Ballistic AE: U14.47,L0.0
BallisticsARC: U14,L0.02 (Seems to have hard coded earth effects on. 0, 0 location and 90/270 to nullify earth effects.)

Earth Effects and Spin Drift On: (Shooting at the north pole (90 degrees) shooting directly south 180 degrees. Technically any direction is south. )

Strelok Pro: U14.5, L0.4 (Doesn't seem to ask for latitude how does it know?)
4DOF: U14.4,L0.36
4DOF (BC-G7): U13.64,L0.36 (Again 4DOF in BC mode is quite dumb, steals earth settings from 4DOF side.)
Ballistic AE: U14.47,L0.45
BallisticsARC: U14.4,L0.3 (90,0, shooting 180 to add most earth effects.)

They all seem pretty close, except for 4DOF in BC mode. Maybe it's stupid on purpose to make you miss with it, so you will appreciate 4DOF? Who knows. I smell some marketing BS.

Strelok is pretty neat but how do you tell it where you are on the earth and which direction you're shooting in?

 

[J McGriddle]

Strelok Pro uses internal gps for latitude and you can point the phone at the target for azimuth.

 

[chevy_man]

I've been using strelok pro, and I'm having a hard time finding anything to bitch about.
It just works. Which is about the absolute best thing you can have.


My Dad did have issues with the dope being off from 4-800. I showed him the multi-bc g7 and it's spot on now. He was just shooting and correcting before.

 

[260284]

I used the free version for a few years with my 6.5 Grendel and a 223. Upgraded to Pro 4 years ago and it has been great. I just build a 22BR PRS rifle and only shot it out to 400 before my first match. I used the G7 of .274 for the 88gr ELDM and made hits out to 1034 yards at the match.

 

[jdubrr]

sounds like I need to upgrade to pro

According to Horus , they invented straight lines and intersecting lines .... I hope US Optics and Leupold
kick em in the nuts in their court case .

 

[frank320]

Definitely, it is worth the upgrade. It locates and sets all of my various scope reticles, works for all my guns, from high power powder burners to high end PCP airguns, to break barrel rifles.

Great value for money.

 

[JCARL]

Love Strelock Pro. Would be worth it at double the price. Thanks again, Igor!

 

[Randy_Lahey]

I have no basis of comparison, but I’m happy with StrelokPro. Has all my acss reticles and dope seems pretty close to me. Sometimes a bit off, but I’m sure that’s my fault for bad inputs of information. Really nice for the money
