john bowket blue printing.

How does JB know how accurate the rifle is to begin with? It is entirely possible that it can come back and not be as accurate as it went to them and I know this for a fact; I sent two springers back to JB (years ago) as they developed ridiculously heavy trigger pulls. Not exactly the same granted but I have seen recently on various forums that it sometimes takes more than one attempt to get blueprinted guns cock on. That's what their guarantees are for I suppose.

now id assume that if he was going to check how accurate it was after working on it, that he would more than likely check it first to see if there was any underlying problems that need sorting out before the blue print was done.

Agreed

On a production gun , +/- 3 thou ?

 

I think you`ll find the tolerances much more than that .

 

How can he do it ? he simply will change the part .

 

I am certain of one thing , if the tolerances at BSA were +/- 3 thou then JB would never have to do anything to them .

 

and the other side of that is if they are happy to let a rilfe through quality control that is not as good as is can be , then shame on them .

 

Seems you are not aware - John Bowkett & BSA are No Longer working together

 

Brought about by many issues -

 

I have one of John Bowkett's Scorpion .177 Single Shot rifles

 

Supplied by John as a Test Gun and used by many @ Lea Valley as a Club Gun

 

Has resulted in many more BSA Scorpions on the Range

 

Many still borrow my one stateing there is a Difference and many have had there's Bluprinted -

 

My understanding is finishing it off as a Hand Finished Gun

Instead of a Mass produced Gun -

Well I picked up the blue printed scorpion on Sunday, and I couldn't be happier with it.

We are not talking about underlying problems though; we're on about a rifle that is already accurate & consistent but sending it for a BP. I don't imagine he has time to go out and test each rifle for accuracy beforehand if it doesn't have a problem. Yes, it can come back worse and although unintentional it happens. Two examples:-

 

1. Zini had his springer tuned and it came back over the limit. (Yes the expert put it right straight away)

2. http://www.airgunbbs.com/showthread.php?608235-To-blueprint-or-not-to-blueprint-that-is-the-question Post 14, same thing.

 

Under the circumstances I can't think of how it could be any worse (handing over a rifle over the legal limit). If these rifles are being accuracy tested then the results may be in question due to the increase. JB sends you an example of his testing with his acceptable tolerances (grouping). As good as they are are they better than your own? I don't know but if my rifle was as accurate as my R-10 was I wouldn't take the chance. When I get another R-10 I will send it to him but not whilst it's in warranty that's for sure.

Bob , I am well aware of the situation with JBand BSA , far more than I'm willing to go into on a public forum . Also the Mk1 R10 troubles , again not wanting to get into it .

 

And as for Si's springer being 'hot' ? Do you mean the SFS recent purchase ? If so I think you'll find its bedded in and ( as all responsible shooters know ) this CAN cause a increase in power . I'm sure the owner and tuner are both well aware .

That's the one, crude example granted but it does show that there is no guarantee the moment it leaves the experts. I talk to Darrin (XTX) every Sunday and he says that many people expect the gun to more accurate. More accurate than what? that's subjective according to what the rifle is already doing as well as each shooter and their capabilities. If it puts pellet on pellet already what are people expecting. You can assure them of a well fettled rifle but the accuracy isn't guaranteed imo.

[robwelsh 354]

Getting a gun blueprinted makes the overall gun nicer to shoot..the nicer it is to shoot, the easier it is to shoot. By getting it more consistent an smoother isnt going to make the gun any less accurate.

[Pink or stink 162]

Agreed, and i'll be sending mine to him soon but I won't expect him to make it any more accurate either.

[Buster321c 1,010]

Si's springer is an unfair example and it certainly wasn't over power when he picked it up , I will vouch for that because I was with him , and what RFD in their right mind will allow an air rifle out the shop if its running hot ? . As with all new guns, once it beds in it will increase . That's a certainty . On the other side of that though , you get people moaning that their guns only doin 10.5 and its only had half a dozen pellets through it . We are all responsible for our rifles , weather its doing 8 or 11.99...... And until the government introduce a 'standard' that we can all relate to there will always be a grey area where , as a rough example , a second hand can be purchased and theoretically the owner could be in possession of a section one firearm without knowing it .The example on BBS , I've not read it to be honest , but there's always chrono results that differ . One may read one thing , and another something else . In engineering , you will know that things need calibration. This way we can check that all vernier and micrometers read the same , and any variation can be accounted for . Ultimately to be certain there are no differences don't all RFD's need to work to a standard ?
