IMO the telling points are the ones like Jay makes above:
"Almost all (maybe all) of the records were set with 6mm Dashers and many were smithed by John King of Kila, MT."
The thing I see is.....
obviously Mr King has the bugs worked out of his DAsher system!
By the same token, if you have a PPC built by any of twenty real BR gunsmiths AND YOU STICK WITH THEIR SYSTEM you can win..... but start mixing and matching and years of work go out the window. A perfectly matched SYSTEM will allow for fine accuracy. And if you want to just buy a winning rifle today it's 'stremely hoovis to just call one of the pros and buy the whole gosh-darn setup. And it'll most'en likely be a .262nk 6PPC....... ((((of course I'm referring here to 100-200yd stuff. REFERENCE only lest someone leap in and howl "ooohhhh, so now you're saying the PPC can win 1000yd matches????"
))))
Now, does this mean that Gene Beggs' work with bone-stock 220 Russ cases and ones popped out to 6MM is useless? Can we "look at match reports and see that Beggs is blowing smoke???"
Absolutely NOT! Gene is carving a new path, kinda'
..... he's applying proven techniques to his Beggs cartridges and they're shooting lights out,
as they should. Gene's a careful craftsman and the potential is there.
Now, regarding Begg's RIFLE DESIGN ...... THAT is a departure from the norm! I gotta' give Geno some really big pats on the back for his daring use of unconventional methods..... but there's really no reason for Begg's cartridges not to shoot.
Just like the 6.5X47L case...... whether you leave it alone, squish it down to .22 or .243 or blow it up to something bigger, IT WILL SHOOT, because it has to. Provided it's handled correctly.
Like anything else still in design phase, there are a thousand ways to pus it all up..... The 6BR is a perfect case in point. For YEARS it had the reputation of an also-ran. For YEARS people jimmy-jacked it six ways from Sunday but very few folks realized that the KEY was (is) in fit and fireform. Make it like a PPC and it'll shoot like one. This may even mean shortening it a little, but it WILL include proper fit-and-fireform.....
So if it doesn't shoot, be it a 6BR, a DAsher or a X47L, something's wrong with the build. Not the case.
And yes, a winning 600-1000yd setup today WILL shoot dots at 100yds. Whatever it is, if it ain't shooting dots you'd better pray for wind...... and luck.
LOL
Now if I can just locate some of those darn new .308 cases German's raving about!
