FTE can accept multiple velocity bracketed BC's. It has several stored in its memory and the software author just updated it to accept user define-multiple BC values.

Re: Questions about Ballistic FTE

I thought fte could convert g1's to g7.

It does convert to G7 if you ask it to. However, I noticed the other day when I did this it took a multiple velocity bracketed G1 BC and converted it to a single G7 BC. This could have been an error on my part. The single G7 BC did put me right on though.

Re: Questions about Ballistic FTE

Sorry if it seems like I'm changing the subject, but I've got another question with fte. When I zero the bullet drift from spin, fte also zero's the wind drift. When I physically sight in the rifle at 300yrds the spin drift is zerod. When I run fte and i throw in a 10mph 90deg wind it still shows no drift at my 300yrd zero. If I turn off the drift zero setting everything looks ok, but I know it's not taking into account the spin. Does this make sense to Any one, or do I just sound nuts. Maybe I'm just missing something . Thanks

I realized the very same thing last night. I think my work around will be to dial the spin drift in my scope as part of my 300 yard zero and set the drift zero setting to off.

Re: Questions about Ballistic FTE

That works for your 300yrd zero, but if you've got a 750yrd shot and a left to right 5 mph wind and you've got a right hand twist you have a pretty
Big variable on your hands. I think the best thing is to run the fte to find the spin drift with it being zerod, then run fte to find the wind drift not zerod. I wish they'd come out with a up date. What do you guys think?

Re: Questions about Ballistic FTE

orangeride your right, what I mean is I will leave the zero setting "off" and just zero my rifle with the spin drift included in the zero for 300 yds.

I don't think you need to run your shot twice through FTE for wind and spin drift, unless you want to know what each is separately.

I've been thinking a lot about the wind direction and I think FTE makes since if one punches in the direction a flag is blowing. So in a headwind the flag is actually flying toward 6:00 and a left to right wind the flag is flying toward 3:00. This convention seems to make the most since and everything comes out right with the FTE.
