If "The Industry" struggles to see the logic in offering, perhaps even standardizing, fast twist barrel in .223" and .243", how likely are they to embrace change for the 270, when the majority of 270 shooters are probably shooting 130 and 150 grain factory ammo?
"The Industry" is slow to embrace change and seemingly reluctant to alter the status quo. I know a guy who is well connected at Winchester/Olin and they won't even make enough ammo for "seasonal run" cartridges to keep prices for many of those Winchester introduced cartridges below the scalper level.
