Anyone know of a source for CFE 223 load data for 6mm Remington? (Hodgdon does not publish any. They do publish CFE 223 data for both 243 Win and 243 WSSM.) Brian

Mad? What, me worry? ;-)

Huh? !@#&$%

Ok, I have some enlightening figures for you: Rifle: Rem 700 VS, 223 Rem Chamber length: 1.780" (i.e. 0.020" longer than SAAMI Max Case Length) Brass: W.W. factory loaded ammo Brass length: 1.755" Bullet: Nosler 40-gr BT Bullet length: 0.693" Bullet boattail length: 0.045" Bullet protrusion...

PS Another bullet I shoot in 223 is 50-gr TNT, which has a very thin snout and, even with a flat base, leaves little for the neck to grab if seated out near the lands. Brian

Not much. With 40-gr BT the boat tail leaves very little actual engagement. They're barely hanging in there, you'd shake your head to examine one. But, they shoot fantastic, and I mostly single load them, not out of the magazine, so they don't need to be very robust. While conventional wisdom...

Of course. I use Sinclair chamber length gauges, and make a permanent dummy gauge for every rifle I load for. There's no reason to trim back cases, except for batch uniformity, if they are demonstrably well short of jamming the ends. Brian

The Winchester brass I have been using in 223 are from factory ammo. They started out about 1.755" as I recall, and after ten or so loadings they are out to 1.760" or "max case length" but my stock R700 VS chamber is cut .010" longer than that, so I leave them be, as I need all the neck I can...

and ... Are your case displacements in grains H2O to overflowing?

Thanks, Scott, excellent presentation. Are the case displacements in grains H2O to overflowing? Back to 375 Ruger (not pictured): Where would it fall down as a 26 Nosler case forming parent? Brian

Interestingly, Wikipedia articles for 375 Ruger and 8mm Rem Mag (parent for 7mm STW) say both cases hold 99 grains H2O. (Different neck capacities needs to be accounted for.) So the question becomes: What existing beltless case can be reasonably used to form 26 Nosler? Brian

Cool, thanks!

The author of the Shooting Times article opined 800 rounds barrel life. The S.T. article shows a simplified cartridge diagram, with some key dimension missing, but it appears to be essentially a necked-down 375 Ruger. Can anyone provide some of the missing notation, such as: * Length from base...

I shoot 87-grain TNT in my 250-3000 Ackley Improved at around 3400 fps. Never had a coyote run off yet, they tend to just plow a small furrow with their chins. :wink: These TNTs are very accurate, as are the 100-gr BTs which I launch at antelope from distance, but which would make fine coyote...

The guy who gave me the Nosler 223 brass took them back, and gave me a box of Lapua. :grin: Brian

Vihtavuori uses the same two-dimensional format as Western Powders, but they do not list TAC on the same row (~speed) with H-335 as Western does, rather they line it up with H-4895. So as always you cannot trust burn rate charts for making any useful decisions, even to tell which of two...

FWIW, I just found an old thread on a the "longrangehunting.com" forum where a chap said he had over 2000 rounds of 22-250 A.I. through a BlackStar barrel, all moly bullets, claimed accuracy "in the .3s" and had never seen a drop-off in accuracy.

Last night I got out my R-700 custom in 250 A.I. which has only ever seen moly bullets. It has a BlackStar 17-4 stainless (i.e. tough!) barrel with the bore electro-chemically polished using their proprietary process. So this particular barrel is probably an outlier when discussing moly build-up...

PS and FWIW: Here's what Brownell's publishes. In essence, they say removing the moly (and everything else) periodically is routine maintenance: http://www.brownells.com/.aspx/lid=1069 ... aintenance Brian

Cole, Since you have been so generous with your advice, may I request a bit more? Suppose I want to revert to plain copper bullets. What is the bes and safest method for removing the moly and cleaning the bore back to "nekkid"? Brian
