Cases aren't difficult to find, you just have to look a bit.Good, but not best….where are cases for sale??? Typical twist rates are slow too, so ammo follows that trend.
The diameter of .277 is 7.0mm. I was simply trying to make the point that nomenclature and actual numbers are very different. .284=7.2mm.no! 270= .277, 7mm= .284
but 270 caliber does not equal 7mm caluber designation. your pt is valid, but you did not elaborate at first. and tgen if you bore or lands, it can of course get more complicated. lol.The diameter of .277 is 7.0mm. I was simply trying to make the point that nomenclature and actual numbers are very different. .284=7.2mm.
actually, .27559 is 7mm.The diameter of .277 is 7.0mm. I was simply trying to make the point that nomenclature and actual numbers are very different. .284=7.2mm.
Lol.actually, .27559 is 7mm.
True but 7mm is closer to .277 than .284.We should probably add here that you will never mic a 7mm projectile that does not measure 0.284 inches.
Might have some neck tension troubles seating the .277's in a 7mm case.True but 7mm is closer to .277 than .284.
A .270 takes .277 bullets, not .284 bullets.I'm well aware of that and have been for a long time. The measurement of .284 equals 7.2mm, the measurement of .277 equals 7.0mm. Get it?
The bore isn't.True but 7mm is closer to .277 than .284.
Without a doubt that was their all time best seller.I think when it comes to the 7mm & 270 WBY cartridges, Weatherby doesn't really appear to give much support to those 2. You don't find either cartridge chambered in their Vanguard line, like you do with the 240, 257 & 300 WBY, and only a few Mark V rifles chambered in them. Grant it I believe their 300WBY is their flagship cartridge, which gets a lot of support from other ammunition companies as well, which helps a lot.
