Even though "science" and the shooting public is putting a premium on the 6-7mm sweet spot, the twist rate of factory offerings for the 270 Win market is stalling it's advance, which kills other 277 bore offerings.The new 165ablr would be a good fit in the new cartridge. But it's not enough to make me go to a 270. Nothing wrong with the good old 270. Yep. Nothing wrong with the good old 308 and 3006 either. Except they are boring. In building custom rifles for 30 yrs and I've built one 308 and one 3006 and I don't even own a 270 reamer because not one person asked for one yet. The guy that bought the 308 already called me and said he should of listened to me and did a 6.5creed. But he already had a 30 dollar die set. And some used brass. So he stayed with 308 for those reasons.
