Twist rate Kozak FC 550

[jdh2550]

I am trying to setup Strelok Pro for my Zbroia Kozak FC550. None of the materials include the barrel twist rate. I emailed Zbroia and got this as a response "All our barrels have 1 turn of a twist rate per each 450 mm of length"

Does anyone know the twist rate that I can plug in to Strelok?

450 mm = 17.7165 inches,, thanks for posting it, I was wondering,,,1 to 17.7

That's what I had calculated also but it just didnt seem right. Thanks for confirming my math! If we both came up with that I am assuming it's right. Now I just need to do some shooting over the chronograph and measure scope height.

There is a thread on here from when this gun was first introduced and it said 1:17.7 twist
