Tuning Altaros in Gamo Urban

[Cbourbeau32]

I decided on and ordered the Altaros regulator for my Urban. I would like to hear from anyone who has installed this regulator in their urban. I'm looking for psi settings for the reg and the resulting pellet performance. I will mostly be using jsb 18.13 grain.

Thanks, Charlie

My Son has an altaros in his Urban. I tuned it for him for the same pellet you are using. His is set at 145 bar and he gets 25 good shots before it falls of the regulator. Cronyed with an FX chrony yielded the following results:

744 Ft/sec average for 10 pellets with a deviation of only 5 fps. Group size at 20 yards was 3/8 in
