Don't throw the Collet die in the bin ! Buy a Redding Body Die to FL resize every time and use the Collet Die for the neck. Excellent set up for a fraction of the cost. and avoids those damn expander balls

No you don't, but you can if it makes you feel better. People do lots of stuff with a theory backing it up but with no data driven evidence to demonstrate any benefit. Its more superstition really than science.

None. They are all as bad as each other 😂. 6.5 CM "you can get factory ammo" yes loaded by Hornady. The same people who don't seem to be able to make two bullets the same length or decent brass. Feel free... 260 mag length, heavy bullets and loading depth issues. Swede is just an oddball that doesn't do anything the others can't but is longer and takes more powder. So the CM fanboys tell me. Lapua can't get ammo. Really. The "benefits" is an exercise in hair splitting of the finest dimensions...

Keep shooting lead until it is banned (if ever) better than the toxic heavy metal alloys ....

Who won the rifle ?

The effects of Coriolis and Spin Drift look an order of magnitude high ? Your data not mine, but a quick look at my 6mm load it seems 2x my values? Odd. Litz quotes powder sensitivity rates as : Good Double Base 1 fps/ ºF Average Single 0.5 ºF Best Single 0.2 ºF So part of the answer is you don't run a powder @1000 that you think is 2 fps/ºF ?

Heard Avery on the radio at sparrow fart this am. Said he was surprised NE did this as they were arguing the licences should not be renewed next year as is, not that they should be withdrawn immediately. Said they understood the pigeon issues and didn't have a problem with that, kind of implied crows as well maybe, never mentioned anything else. Not sure who put him in charge though. Really this is a precursor to them arguing that natural fuana should not be "annihilated" to keep a " few more pheasants running about in January". His words not mine. So listen up BASC this is coming your way shortly..... Came across as a bit of a weirdo academic to be honest. You wouldn't have him to the house 😁

Previous action was bedded in ?

Ok so ... 1. It is a small effect. The errors inherent in the numerical models are likely to vary and on such a small effect may well produce different results depending on their exact initial configuration. How about that? 2. Confucius say "Man with two watches never knows the time". Who says he is wrong, maybe he has a better model. Plenty other software has spin drift and coriolis options, as you point out. So why the cynicism? 3. They have other things to worry about for now that generate bigger errors? As the game progresses that may not always be the case. There are heaps of scientific advances that are don't have practical usage for decades. The AI algorithms were written tens of years ago but until we got big data, cheap compute, and the ability to load large databases across multiple processors they weren't much use. You can't just advance science when it suits you. Just wait until you can profile the wind with a laser. As for the rest of it, you are being obtuse and I will leave you to it.

They are all better than mine ! 😀

Quite right too. Nothing more boring that looking at someone else's shooting scores. Well that's not really true, its listening to them tell you how they ended up with that score. 🙉

See thread elsewhere on this site for debate on validity (or otherwise) of said methodology.

Easier if everyone shoots the same thing right enough.

Which is exactly what I do with my MOA/MOA system, using the reticle as a ruler. Why MOA? That was what was for sale at an attractive price. The only benefit I can see are that remembering the 10mph wind numbers are really easy for my hunting load as they correlate directly to the 100 yard multiple. Not the biggest reason, eh. I look at the equivalent MIL model and think the turret is a lot less noisy and would be easier to read, with my worsening eyesight. Maybe not, out of focus is out of focus. Not paying £2k+ to find out. An angle is an angle is an angle.

The sport makes it too hard to play. Everyone has the probation before you can join no matter what other memberships/qualifications/authorisations you have. Well fine, but they expect me to drive x hundred miles to shoot in their comp (for which I miraculously am qualified) but I can't shoot at the club on other days without jumping through loads of hoops/ additional expense/ on some poxy 100 yard range before I am allowed onto the range that I can shoot the comp on? How does anyone expect to grow a sport with a crap attitude like that? I don't get any of that sh*t with the shotgun so I shoot in competition all over Europe and I can turn up to any ground with my cert and shoot whatever I feel like. I know where my $ will be spent...

except a wife....

Not really. If you have definite features/performance in mind it is easy. The majority of production rifles have features which are more about cost than function and if you don't want to accept that then there is a bit of a hunt for a rifle that does not compromise in areas that you deem important. Combine that with calibre choice and off you go.

What is it that the PRC gives us that we can't already get ?

Not sure I really want to ask this, but can't resist... Do they really do this ? I don't think they do it up here ? Waste of time, how is ground safe for 222 but not 308 ??

Good man that's excellent. I made a set by hand last year and it was a revelation. Bit fiddly to do though so the website is a great help

Got some 208 Amax to 2650 on a non SAAMI coal. Bit stiffer but nothing to write home about. Rode the wind well but was hardly flat. Seemed to defeat the point to me, would be better off with another cartridge 6.5 or 6 if you want the windage but with flatter trajectory or 3006/300WM if you really want to throw a bullet that weight. Fun trying though. Not as much fun as 200 gr Subsonic I digress...

I can see the stalker inviting the esteemed overseas guest to carry his own rifle. Now I lug a heavy thing up the hill but I don't fancy that one. There may be some estates that would let someone shoot at extended ranges but I would be very surprised? Its some wind call required on a shitty day up the hill to drop a stag at a mile. Or alternatively give the deer a miles head start when you wing it. Good luck on keeping up with the stalked... It's just not gong to happen is it - I suspect the OP would find that estates are 'fully booked'.

Well yes and no. Clearly at the extremes yes, the firing solution becomes more sensitive to a range of variables and needs more precise calculation particularly for small targets. That's why you have the MOA/Mil sub tensions on the tape. Nothing stopping you using it in that mode. However it is also a no. Atmospherics are not a key fundamental at all ranges; it is possible to just use an 'offset' for the atmospherics in many circumstances (for me at least); for larger targets where speed is required then the drop calcs are done offline giving a faster but still pretty accurate shot. So for short and medium ranges I can dial in a faster elevation correction while still retaining the flexibility of the original scope sub tensions. All very clever. In reality I can see that damn numbers in the field without my glasses...

Excellent. Thanks for this. Worked perfectly. Except my eyesight ! Rolled a hunting version for my 624i - i.e. big letters. Very neat, I can just whip it off and put on a range version.

I think you are doing yourself to describe that as DIY !
