Big Ed B51 arrived!

[DanoInTx]

Yes, I know about SCUBA tanks, hehe....  Problem I have is that if I am going to invest in a tank I am going to need one that is at a higher than 3000psi pressure because I have other guns that like 3000psi fills.  If I start at 3000psi then every fill will top my guns off lower and lower.  Doubt I'll find a 4500psi tank for $60, then finding a shop that will fill it is another story, don't think there is much SCUBA diving going on here up by the Texas Oklahoma border, but I could be wrong, maybe people dive murky chemical filled Lake Worth?  I agree pumping is not my favorite activity, but driving to a shop and paying to get a tank filled doesn't sound like a bunch of fun either.  Nope, I'll stick to my old pump, just now I own guns that will stay filled between shooting sessions.

Wasn't gonna buy another Chicom gun, but then I started hearing of all of the wonderful things Big Ed was able to do with these things so I hadto give it a shot(pun intended).  I figured if I got one done by a guy who knows how to do them right, well there shouldn't be anything to complain about...and if I still had complaints I could definitively say that I would never buy another.  The B50 I owned wasn't a terrible shooter once I got it shooting, it was just by the time I had it shooting ok I was tired of messing with it....and it still leaked!  This gun is like Night vs. Day compared to the B50 I owned, and I say that is how it is because of Ed's work...I would never buy another out of the box without a tune, I just don't have enough hair left to pull out:)

Shot it somemore yesterday afternoon.  I just can't miss, one tiny hole, all day long, until boredom sets in.  I need to take it out for some long distance shooting now, then I can really see how it performs, which I suspect will be great.  It's tuned to shoot right at about the same speed as my friends AA S410 Classic, but in .177 with a heavy 10.5 pellet, his is .22 at the same speed with an average 14+ grainer...should sling it out there pretty good I reckon:)

The LOP on the B51 is actually shorter than the B50, by almost 1 1/2".  I agree what you say though about the ergos on the grip helping a little also, you need 10" long really skinny fingers to shoot the B50 without modification, and after modification you still need 9 1/2" fingers:)

Yank me about my purchases all ya want, I buy and sell so fast I don't have time to be offended...hehe!

Speaking of buying and selling, put me on the list for when you get tired of the B51 :-)!  I'm still not sure I'd have traded off the 50 if I'd gotten the t-hole stock in first, that thing really felt good.  Still, it's pretty nice having 2 Talons, so I guess it all evens out.  Later.

HEHEHE....

I wonder how much BigEd charges to tune a customer's B50. As much as I'd like to do it myself, I just don't have the time.

Looks like $25 plus shipping both ways:

As much as I'd like to do it myself, I just don't have the time.

 If you need your barrel crowned you may need someone else to help out but for a basic tune on the Bam you are looking at five minutes time.
Change the hammer spring, set the trigger and "maybe" the transfer port. five minutes work with the wrenchs it came with and Ed will sell you the spring.
  http://www.klickcue.com/air_rifle/b50_51/technical_details_for_adjusting_the_bam_b50_51.pdf    gives you a lot more than you need to know.
 Stock except for the  hammer spring change in .22 with a 2000psi fill will give you 865fps w/14.3g pellets.

Mine chronographed at 867 fps with 14.3 gr CPHPs . It's bone stock, except for straightening and adjusting the trigger.

My first B50 .177 would launch a standard weight pellet at well past the speed of sound, but accuracy was terrible at that speed.  When the FPS dropped quite a bit, then it would group rather well.  The problem with the stock spring out of the box was that the FPS curve was more like a straight downward ramp, possibly good for hunting where you only shoot a few shots during an outing, but not good for the long distance plinking I enjoy.  There were a dozen or so shots though that were real good in the accuracy department, then the POI would start to drop.  I'm pretty happy with sacrificing a bunch of top end grunt for many more accurate shots.  Still haven't chronied my new one, usually dark when I leave for work and dark when I get home these days:(  When I have had some time to put a few shots through it I have been very pleased with shot count and consistant grouping, but then I still have yet to take it out for a long range spin....so we shall see!

My next step is to make a better trigger blade at work.  Ed straightened this one out, but it still feels like a cheap cast brass piece to me that doesn't match the quality of the rest of the gun.  Not yet sure if I'll make a whole new piece, or just lop the blade off of the stock piece and just make a new blade.  Maybe just reshape the current blade and add a shoe.......huhm, fun to find out what I do:)
