Yeah, mang. I have a B30-1 in .22 cal. It was a good shooter out of the box, despite the rough trigger and harsh twangy firing cycle. I tuned mine using James Maccari seals, tune kit, and lubes. It made an unbelievable difference. It's a smooth shooter with a smooth, solid thunk. No more roughness or twang. I stoned my trigger assembly contact surfaces and the trigger is pretty darned nice. Not as light as a Rekord trigger, but I bought this gun to be a hunter, not a match gun. It works just fine as a hunter.
IIRC, mine is averaging 765 fps with 14.5 grain RWS .22 Superdomes. Knocks the snot out of squirrels. I love mine.
I highly recommend it. Either way you go, get it tuned with Maccari parts. James Maccari parts have the stellar reputation because they ARE as good as people say, maybe even better.
If you buy yours tuned from Mike or if you buy one and have Gene tune it with Maccari parts, you will not be disappointed. Especially if you shoot 50 or so rounds through it before you have it tuned, just so you can appreciate the difference.
I have a B40 that I bought, tuned, from Mike Melick and it's a fantastic shooter also. It's about 30 fps slower than the B30, which isn't bad at all. It's a fantastic shooter, too. Just depends on what style of cocking lever you prefer. The B40 is shorter and handier. The B30 is a little more powerful, and easy to install a bipod on, as I did with mine.
If you search for threads posted by me, you'll find one about some chronograph testing I did. It'll give you some insight.
Basically, if you want an air rifle that tunes up nicely and knocks the snot out of small game, the B30 is a good choice. The chinese chose a good gun to copy, when they cloned the RWS 48.
Hopefully soon I'll install my new Maccari seals and tune kit in my Weihrauch. Gonna get rid of that twang and get it back to shooting like it should.
My friend daveshoot flatters me. How are you doing, dave? I haven't been around because my short attention span has been compelling me to spend more time with my pocketknife collection lately.
Good night to all.
