me too.

From NRA General Range Orders: c. Cartridges which, when normally loaded, would exceed the ME/MV limits of any specific range, may not be used, on that range, even if downloaded. How do we interpret that for a wildcat especially a calibre designed to shoot flat and fast? Short of chrono'ing or running QL to model the MV to check it's below 1000m/s (all ranges at Bisley) it's a difficult call. Some popular calibers stoked up and shot through long barrels will exceed 1000m/s. So is it reasonable to assume necked down cases will have significant increased MV than the parent and therefore certainly possible to breach limits ?

That'll put a cat amongst the pigeons ! I wonder if this will be taken up by others - like DIO ?

On a military range (which many of us use in the UK) the NRA rule is "law". Wildcats could be used but it's up to the RCO to decide if they can trust that the necessary tests have been done to ensure it's within range limits and that no risk to the shooter and others will reasonably occur. If it's HME the appropriate rules apply. If it's a stranger to me as RCO, presenting wildcat loads for use, I'd want to reasonably satisfy myself that the person is competent and truthful about what they have. If in any doubt it's a firm no from me.

😊 I have contemplated just making a 15mm spacer to put under the threaded bush, I would prefer more thread engagement to ensure maximum stiffness. I may resort to making a new bush, £10 for steel and some time in the shed with my lathe, seems like a plan !

Hi I have an RCBS Rockchucker which is a great press except it's a bit short for .338 cases. Various dies are only a few threads screwed in. I'm aware that the new model is longer in the body because of this problem. My question is does anyone make/know of an extending top bushing (1.1/4 x 12 ext - 7/8 x 14 internal) that will space the standard die further out with a decent thread engagement? I guess I can make one but if there's a simple solution I'd consider it.

I have a spare Sako 85 bolt stripping tool surplus to needs. It's the black plastic knob with a cut-out for the bolt end. As new, never used. The rough edges around the cut out is just moulding flash, not damage. £28 at Brownells - I'll do this one for £15 plus £3.50 p&p

I'm not arguing "more accurate" I'm just saying CNC does not automatically equal magic accuracy. For example, if you need to turn many components the same, a copy lathe will do the job. A jig borer can be set up to gnats pubic hair accuracy, a match grinder (many made by the Swiss) will turn out near perfect components. As you say, in-cycle gauging is valuable but not limited to CNC.

CNC works to tolerances just like any other process machine. For sure a well set up, top quality and properly maintained CNC is pretty accurate and repeatable (tool wear compensation accepted) however CNC machining isn't inherently more accurate or repeatable than alternatives if jigging/fixturing etc is sorted. Most CNC turning and milling use ball-screw driven by encoded axis motors - the point being is that the position feedback is indirect and subject to lost motion errors unlike a linear feedback digital readout directly coupled to the machine axis. CNC is not the same as "super accurate".

I have just taken delivery of an S&B PM2, Vortex's loss: I wasn't willing to wait four months even for a very good (but not exceptional) scope.

Isn't it a problem getting the fox to stand still while you straddle him with fire ? Not very sporting 🤣

did he do that? Did he say he'd discovered this relationship himself?

Can you "steal info" surely the transfer of knowledge is the foundation of all learning? Why not 21.8 or 21.7 ? or something else entirely. Possibly a rule of thumb but not science. An interesting article but I think it's unreasonable to suggest a barrel length without reference to cross sectional area, the profile, Young's modulus of the steel and other factors such as the action interface stiffness. What about the varying impulse from differing loads? The fact their shooting results were superb doesn't necessarily back into their assumptions on barrel length. If you have an article where they test barrels in differing lengths, differing profiles, differing cross sections etc etc I'd be very interested to read it.

Can't help you there, I'm not familiar with that set up. By the way, you seem to be quoting your own original messages - try putting text below the quote box

SOLD! PM me with your address and I'll send you my bank details for a BACS transfer £22.50p

I have no idea, check out the website

Hi I have Vortex objective cap = Size 0-50 fits 50mm objective. and Eyepiece cap E-10 (where on a Vortex Viper PST) £20 plus £2.50p p&p UK mainland The objective cap has a superficial scratch

Good scope, ballistic turret is a waste of time but it will work if you make notes

Bit of a moot point now as new Razor 4.5-27 x 56 are unavailable for about four months (according to the importers). I have looked through both the PST and Razor - the razor is better for sure.

It's vice not vise, we're not American 😁 If you need a recommendation on such a simple bit of kit: Get a big one, Irwin or Record. Have a look at Axminster Tools, their Chinese vices are pretty good and good value (I have one). You need a solid bench to mount to or you're wasting your time. Also Screwfix.

K624i and K525i. Nowhere to be found in the UK - plenty of ads but no actual stock

Yes James, £185 and I'll pay the p&p (mainland uk)

Also unavailable at the moment

OK, I have feedback from Cody at Vortex: "Thanks for your interest in Vortex Optics! That is true and you will get more adjustment out of the MRAD version of that optic and it will be the 28.5 MRAD we have advertised on our website. I hope this helps and finds you well. If you have any more questions or concerns just let me know, I would be happy to help anytime!" No explanation why but confirmation that the mrad scope has more elevation than the moa scope. Ho-hum, doesn't matter anyway to me as the Vortex 4.5-27x56 is now unavailable in the UK and on up to four months back-order according to the importer. Their loss is S&B's gain (and my wallet needs an extra squeeze).
