Umarex Notos..how many regulated shots stock?

[seanfrev]

I'm getting 30 shots before I drop below 1900 PSI with cphp. With the second and third 10-round groups much tighter than the first 10 round group. Under a dime 30.
For some reason I was expecting low twenties before dropping .
Im guessing this is normal?

You may not be optimized on the hammer spring. If you have a chrony, see if your speeds change corresponding to your groups. 30 shots is not bad but mid 20s is more of the norm.

Thanks I do have a cheap Chrono... I'll check. I'm pretty impressed 30 shots from that little tube.
