  1. The scope is also advertised elsewhere so first come first served.
  2. I bought this scope about 18 months ago to use on a long range benchrest rifle, I used it for three 1000yd shoots winning two of them before I upgraded to a 10-50x60 S3. I then used it again in a 600yd comp finishing second. I say all this because it confirms the tracking and POA retention is good, Im only selling the scope as I have no use for it. It has the favoured MOA-2 reticule. There are a couple of marks as you can see and there is no sun shade with it. The scope is exactly how I bought it from another forum member and Ive priced it the same as I paid for it which at the time was cheap so Im passing that on to the next man. £675 posted RMSD
  3. Guys, Ive got a Seb Max co-axial front rest for sale, its in very good condition. I bought it brand new from Foxy just over a year ago for £1150, its done one season of benchrest. Will take any forend up to 8" - Im looking for £900
  4. Add to the above new load development for a cartridge you dont know. This will possibly take you longer to get the right load than it would to fine tune what you already know about 6.5x47 and again it just adds to the costs. Consumables used in load development quickly add up and at the end of they day all these shots are just a means to an end, bullets primers and powder aren't cheap. Having said that, if you dont shoot much past 600yds I would prefer a 6BR as they are generally a more pleasant caliber to shoot with noticeably less recoil. Im afraid Im in the American camp though, within reason barrels are consumables.

    New barrel breaking in

    What did the person who built the rifle advise?

    Mausingfield 6.5x47

    I think the article you found will cover pretty much anything I can say. From my own experience its a very well made high quality product. Most of the work I do these days is custom action builds, BAT, Borden, Bighhorn, Mausingfield, RPA and Defiance. BAT and Borden are tighter but in a field action I wouldn't want that, the Mausingfield has some clearance that allows to to run fast and very smoothly, the finish on the Mausingfield is as good as the very best and now with the option of PVD coatings as standard it is a real player in the LR Varminting and PRS type build market. Even that bolt knob which is very Marmite actually plays a good part in the function once you get used to it. I was talking to the chap who I built it for only this week and he was saying its a delight to use.

    I dont have a daughter... As for the target, the name of the maker is printed on it, contact him and ask him yourself.

    Mausingfield 6.5x47

    The target isn't mine, I posted pictures sent to me by the chap that was paid by my customer to do the load development. What I do know is he made the target himself in MS Word

    Which target?

    6.5x47L Dies

    They will be keeping the 6.5x47 dies for when the Creed barrel is finished...

    Brass shrinkage!

    Do the cases that have the shoulder at 1.624 still close nicely with minimal resistance on the bolt? If so I would leave them as is and bump the few longer ones back to match them. Trim length for the .308Win is 2.005 and with max case length being 2.015" you still have plenty of room so I would probably trim only the longest ones to match the average.

    Brass shrinkage!

    The cases have expanded to fit the chamber, the material needed to do this either has to be pulled down from the neck area or pushed up from the web - the brass in the web area is considerably thicker than the neck area, the weakest point moves first hence they have shrunk. You may not notice much if any growth on the second firing but from then onwards they will grow, the rate will depend on the charge weight and pressure you are running.

    Reprofile a barrel?

    As I said earlier, there are lots of myths propagated within the rifle building business by some, I dont really understand why? I much prefer facts rather than myths and this question in particular isn't really a hard one to get to the bottom of by looking at the facts. Once a barrel has been rifled, either cut or buttoned the barrel maker may choose to perform a process they feel will relieve any stresses they feel is now in the blank. From there is is profiled and sent out to the customer. From the same 1.350" diameter blank there will be all types of profiles cut right down to the thinnest sporter. All the profiling is done in a lathe, usually with a travelling support to reduce barrel flex and improve rigidity in the cutting process, after profiling there is no further stress relieving done. The barrel then comes to me as say a heavy profile and I then carry on the profiling to whatever I want - how on earth does this differ from the process finishing in the factory? In fact I know that the cuts I take will be a lot smaller and slower than a factory profiling lathe because my machine isn't as rigid as theirs. Ive visited a UK barrel making plant, seen the size/colour of the chips lying in the profiling lathe and so know this for a fact. The only way profiling would be a problem would be if the person didnt know what they were doing during the re-profiling which I alluded to in my first post. When cutting metal there are basic principles of cutting speeds and feeds as well as the right cutting tool geometry and tool coatings that will ensure the majority of the heat created in the cutting process goes into the chip coming off rather than the workpiece. Add to that the use of flood coolant during the cutting process (be that turning or milling) and the workpiece stays cool throughout the job. We have turning tool and milling cutter technology now that allows us to even cut barrel steel dry without coolant and again the workpiece stays relatively cool, the heat goes into the chips being made not the workpiece. Ive turned barrels dry and they never got close to being as hot as they do when they are fired in a rapid fire benchrest competition on a hot summers day. Profiling or re-profiling a barrel blank is quite frankly a boring and tediously slow job on a manual lathe the kind that most rifle builders have. Turning long accurate tapers with a good surface finish will be beyond the capability of some and so its not a popular job that they will try to avoid at all costs, I think this could be where the myths come from? Lathes with copy attachments and hydraulic followers make the job easier, this is where the CNC machines come into their own, again most small rifle builders dont have this technology, myself included. I know of at least three other reputable UK rifle builders who are happy to profile and re-profile their barrels, one has been doing this for 25yrs. When I started building rifles I realised the permutations of barrel profile, caliber and twist rate would mean I would need a lot of barrels if I wanted to be able to turn around jobs quickly without constantly ordering barrels and waiting for them. The answer was to order my initial batches of barrels as blanks, this way I could profile as required, this cost me in time I couldn't charge for but made it possible to hit the ground running at a lesser initial start-up cost. Even now that Im established with a good stock of barrels I still order a lot of my barrels usually in blank form and then profile them myself, sometimes I also buy heavy benchrest profiles and then re-profile them to the spec I need. I would say in the last 3yrs I have either profiled or re-profiled about half of the approx 140 barrels I have used. There has not been one single barrel that has not lived up to expectation, accuracy has been as good on barrels I have profiled as it has been on barrels I have had supplied ready profiled. I dont do the fluting myself, I send it out to a company I trust and again never has there been a problem with regard to accuracy if you know what your doing. My rifles hold 4 of the 8 UKBRA long range benchrest records with barrels I profiled myself, I have also profiled barrels for customers who shoot at world championship benchrest level, if re-profiling a barrel hurt accuracy I and many others wouldn't do it.

    I have found with the rifle building business is it has its fair share of silly myths and superstitions.
