Range Report Ballistic FTE and rimfires?

[TimK]

I've had excellent luck with 3 different centerfire rifles and ballistic FTE. I tried it with my new .22 trainer shooting Eley Target ammo and got terrible results. With a 100 yard zero, the software predicted 4.4 mils to get to 200. It actually took 5.4 mils. Anyone else had poor results with .22's?

Where did you get/what are you using for BC and velocity information?

Ballistic FTE had the load in its database. I chrono'd it to get more precise MV data. I can only assume the BC is correct, but I have no way to confirm.

I saw a post somewhere here if I remember correctly and there was BC's listed for the 22 center fire ammo.

Yes, I found that. BC listed is the same as FTE.

Re: Ballistic FTE and rimfires?

well for me Ballistic FTE seems to run the same numbers as Ifinity6 by Sierra and also Quicktarget also. But I havent tried any rim fire rounds. When I get some time I will run some numbers for you give me you conditions and I will post the results.

I think I just figured it out. FTE shows the correct BC when you first enter the load, then it somehow doubled it. I reset it,and now it's pretty close.

Ok good thing you got it figured out

sometimes if the information is a little off in some parts of the software it will throw you off a little
