Meet QbBob QB78 FT

Well I started with a uber modded QB78 and added lots of stuff too it.
it started has a QB78 .25Cal that shot 950fps it was a ton of fun hit like a truck
would have made a great hunting rifle but I had other plans.

Sold the .25 LW barrel and bought a .177 LW barrel
A extended bolt probe, a bi-pod a AR2078 Thunb stock and painfully cut it.
I have instal a crazzy Scope on this its a copy of a great scope and it works great
for a copy let me tell you.
Its a ZOS 10-40X60 SF with big wheel and I have a sun shade for it, but with curent set up
it does not fit.

still lots of finishing to do on it and some tuning I will tune it for 780FPS with JSB's 8.44G
and use it for FT if I like how it shoots.

So I work on it today ajusted it too 780fps at 10m. I would have like too ajust it more but one of my lights on my crony light kit
just stop working and I was not even shooting at the crony and no I did not hit the crony.

so this is not a real test since 10meters is not all that far, but at 10meters I'm shoting pellets in the same hole shot after shot 10 in a row no problem.
it's very good and my fps do no change more then 10fps and that is one of the reasons I bought QbBob it's shot string is flat across the the board from 3000psi
too 1200psi, this is a wonderful FT airgun, I have almost 1000$ invested in it,

I know I could have bought a Hammerli AR20 and would have shot about the same, but there is something I like of having something custom and from a cheap 125$
starting point,

and yes I will be selling some of my other great airguns to pay for this setup. Disco will be sold soon.

now the tunning part, a bit tricky the RVA is very fine for .177 since this was a .25 build the RVA is a bit long to ajust I got to move it
very slow since it can move from 770fps to 850fps in just 1mm so took some time to ajust but I have it ay 785fps at 10meters from barrel
so this will be where it will stay for FT, rules say max of 12fpe and at 785fps with 8.44g pellets I'm under that,
I did not want it at 800fps since on a hot day I would be over now I have room to play.
But anyway this is a on site in the field ajustable take minutes to ajust now that I know I have to move it ever so little.
this has a shot string that is so close it's unreal 777fps to 785fps all the way from 3000psi too 1200psi since this is .177 I can go lower
in presur and still keep my fps in my original ajustement.

now if only there was no snow so I could go shot it outside 2 feet of snow in my yard.

I been trying to be accepted at my local gun club 50yard shoting range would help me to practice.

QbBob is has good has any FT airgun out there on a bench rest I would compeat anyone at 11 meters it's pellet after pelette in same hole.
get to be boring after a few hours why I need 25 yards to 50 yards to really try it out. this Lothar Walther in .177 is doing a fine job
and even after a few days this set up keeps its Zero after I added a 2nd barrel band.

now next on my list ............. LOL I spend too much on airgun last year and half. I got to sell some more.
