Airgun Technologies U2 choices

[microtus]

My first SS check hit the bank today and I'm treating myself to a green laminate Uragan 2 from Tony. I prefer the looks of the 600 v the 700 but worry about giving up too much speed with the shorter barrel. Is it realistic to obtain mid to upper 900's with a 25-28g slug out of the 600 barrel? Anybody buy the 600 or 700 and wish they had gone the other route and why?

I traded my huben k1 for the U2 700, I love it, but I'm currently trying to sell it just so I can downsize on the length. I got mine shooting 25gr H&N HP2 slugs between 935 and 950, the regulator sits at 125 for that speed out of mine, getting around 120-130 shots. I've turned mine up as high as 66fpe or 34gr going 940. I still had plenty of regulator to mess with and had done no hammer spring or valve adjustment. Also I was still getting around 59 shots with that tune. The 600mm would still have more than enough juice for what you're looking for.

...."Downsize on length"... I realize it's just 4 inches but the length is my biggest hangup. Thank you for the input.

I watched African air ordinance on YouTube shoot 40 gr slugs at 1000 fps out of the 700. The 600 should do what you want with room to spare.

He put his own AAO kit in it though. Without it, he was definitely not able to reach that.

The shorter barrel won, just placed my order for a 600mm Green laminate in .22. If he can tune it to 950 with a 28g Zan, great, if not I'll take what I can get. Ordered some .217 Zans to go with it. I'll try them with fingers crossed before ordering sample packs.

Ah ok. Didn’t realize that

I would suggest h&n hp2 sample packs in 217&218 . My u2 700 likes 218
