I finally had an opportunity to shoot it for the first time today since it is finally all together, I was extremely pleased with the results. I haven't even done the poly transfer mod to it and I am getting 675-680FPS using 14.3gr CPs with the adjuster all the way in. With the adjuster turned down I get about 625FPS using 14.3gr CPs. I shot a couple of 21.1gr Beeman Kodiaks at about 570FPS. 14.6gr Beeman FTS were doing about 650FPS with max power. I imagine the poly transfer port mod will put me above the 700FPS mark with 14.3gr CPs on max power. Shot count on max power setting was about 15-17 shots, with it turned down I can get over 20.
Accuracy is excellent, I am printing about 1/2" at 20 yards without really trying too hard. I didn't take any pics of groups yet, but I will in upcoming days.
Next things to do will be a HDD for higher shot count and maybe the poly transfer port mod. Really, 680FPS is more than enough power for my range of shooting, so I may not do it. But I would like more shots though, so the HDD is a must.
This gun is definitely my favorite shooter so far. It's accurate, powerful and looks great(IMHO). I am going to have a very good time shooting this gun for many years. Thank you to all of the guys(Grant Stace, Tim McMurray, Art Braden, Roy Weid) that make the incredible parts that allow me to build such a fine gun. I couldn't do it without you guys.
Here are some photos of the completed gun in various configurations(open sights and scoped with the LDC). Also there are some shots of the chrony numbers I was getting.
Hope you enjoy, I know I do!
In it's scoped configuration:
Here it is in it's open sight configuration:
Here are the first 6 shots through the chrony with a brand new CO2 cartridge shooting 14.3gr CPs at max power:
The 7th shot I put a 21.1gr Beeman Kodiak through it at max power:
Not too shabby! :)
