if you can't get a 140g burger VLD to a grand at 1400fps with a good working load it's time to give the game away

That rail wouldn't be cheap . Idd put a 200 moa bend upwards in the end of the barrel .Yup !

Was this the CheyTac you were meaning?

Has anyone mentioned 300Win Mag?

Not if you AI it

Just out of curiosity, what does AI'ing do other than increasing the powder capacity? Does it reduce pressure some how?

First the minimum body taper. Less taper= less case stretch. Also a better gas seal and it grips the chamber walls tighter which meant less thrust transmitted on the locking mechanism. Also a straight walled case ejects easier than a tapered case

The steep shoulder slows down brass flow so that= longer brass life. Also confined burning gasses in the case longer and that helped powder consumption

Longer necks, projectile doesn't take up powder space, also doesn't look like hell

That's pretty much how I read it, I would copy and paste it but I can't. I can screen shot it though if you want or send you the pdf file @Gibo

I found the tapered case bit interesting, I would have thought the tapered case would extract easier

Creates a whole lot of heart ache sometimes

So longer brass life and easier extraction......must be more to it?

Its alot of reading I didn't get far

More speed for same pressure.

Fire forming brass has been the only reason I haven't bothered having a crack at one over the years.

The tapered case part makes no sense....

that's its only downfall.It cant be to long before you can buy 260AI cases if you can already get 280Ai.
