Hi Folks,

I've had my Srod for a month now and so far it has met my expectations. I removed the lawyer spring and adjusted the trigger, my first step. Next I installed an Altaros regulator and removed the factory depinger...off to the chrony.

JSB Exact Heavy 18.13 grn. - 3000 psi (fill) to 2000 psi (end)

1) 853.6 ===== 11) 849.6
2) 853 ===== 12) 848.1
3) 851.8 ===== 13) 847.7
4) 854.4 ===== 14) 846.8
5) 850.7 ===== 15) 847.5
6) 852.2 ===== 16) 846.8
7) 849.8 ===== 17) 846
8) 849.6 ===== 18) 844.5
9) 847.7 ===== 19) 841.8
10) 848.2 ===== 20) 837.5

Avg. 849// ES. 12.6// SD. 3.2// AD. 2.5

Gun is grouping 5 shots under a dime @ 40 yds., so I'm good hunting out to 50-60 yds.

I've spent several months reading the forums here, great source of information.
So I need to say a big Thank You to all, you've made it much easier for me to get my gun up and running.

Cheers
Gary
