Brilliant app but my reticle can’t be found

This is truly a wonderful app and I can see why everyone in my area is using it and told me to get it. Just a pity my Leupold Mark 5HD 5-25x56 Front Focal TMR reticle can’t be found on this app. So, for now I’m using the Leupold TMR Front Focal reticle and adjusting the speed after shooting and dialing at further distances to re-adjust the data. Thanks

Developer Response ,

You can select "TMR, Mark 5HD 3.6-18x44, Leupold", it's the same

Handy tool

This app is a handy tool for any person. The reticle with target is a nice perspective on what to expect in the field. Developer also very cooperative is a reticle or bullet is missing from the list. Best money spent so far.

Highly recommended for any type of shooter.
