Strelok Pro vs ChairGun

Jump to latest Follow Reply
I must be not seeing what the issue is? I use strelok pro all the time for several guns and pellets for each gun. You just sight the gun in at a known yardage and the reticle tells you where to hold at any other known yardage. Doesn't get much easier IMO. All my PCPs are sighted in for 80 yards, plug in any other yardage, hit reticle and fire away. Here's what happens when a woodchuck showed himself at 114 yards, gun sighted in for 80. Plugged in 114 and hit reticle.

Here is my email to Boris and his response:



My name is Igor)

Carl you did all correct putting 1.5” in vertical offset. Here is explanation how zero offset works: http://www.borisov.mobi/StrelokPro/ios/cartridges.htm

Another way to solve this task: change rifle zero as, for instance, 150 yards, open Table screen and see what elevation is at 100 yards distance, change zero distance until elevation at 100 yards will equal 1.5”. Leave this value as zero distance

2 ways with same result

Hi Boris,

My name is Carl. I have what I think is a simple question. I have several guns that are sighted in a +1.5" for a Maximum Point Blank Range (no holdover or hold under) to hit my target at any range from 100-200 yds. I cannot put +1.5" in the rifle zero box, so I put in +1.5" in the vertical offset. A friend of mine is telling me this is not correct, but cannot tell me what value to put in the rifle zero data box, since I don't KNOW the rifle zero distance. All I know it is +1.5" at 100 yds.

Do I have to re-zero my gun at a known distance, input that number, and when I'm done, re-zero my rifle to +1.5", which is where I want it or is the way I'm doing it ok, or is there another way?

Seems to me it is a lot easier to just input +1.5 in the vertical offset, than pick a fictitious range above 100 yds and then yuk around trying to figure out where it is +1.5".

If all I had was a couple airguns, I would just shoot the gun at the various distances and mark them down, like you do when you make a turret tape for the MTC Viper. Simple use of a program always has simple solutions. Most guys use ballistics for a LOT more than just a couple airguns.

If you used the mpbr calculator in the app to calculate your mpbr it tells you what the zero distance is for that mpbr. 

Heres a pic

The mpbr calculator tells you everything you keep asking for. Also if you have the velocity, rifle data in the program and the projectile you have the answer to your question. Theres no way you can get the program to tell you the mpbr you want but not be able to get the zero distance. All that data goes together and you cant get one and not the other. You say its sighted in 1.5” high at 100 so all you need to do is open the drop chart and look thru it until you see 0.0 in the vertical correction column and right next to that column is the yardage column. That would be your zero😉

Actually I found it back on September 30, so no inattention, only some people think their way is the only way. I have only had the program for a couple weeks, and haven't had a lot of time to use it. Thought I'd ask since others here claim to know all about Strelok. Finally, I did the right thing and just asked the people who make the program. No matter his name, he knows all about his program, and he made two things perfectly clear:

1. The way I went about it was fine, it is one of many ways to get the answer, and

2. It will give me the infomation I was looking for.

End of story.
