I'm a 270win guy at heart, My father used one, and all the articles by O'Connor did sink in as a kid. But later in life I ended up behind a badge. Then later made Chief. In that capacity I found myself at a trade show with ammo and bullet makers trying to peddle there product to LEO's. I ended up in a conversation with an engineer who made bullets for a well known company. I was more interested in hunting bullets than duty ammo, and so was he. I told him of my hunting with the 270, and he told me something I always remembered.
" We make bullets for a window of velocity", he stated, "we want that window to be a big as possible with a test standard for minimum terminal performance, but you can only go so far. One of the reasons the .270 is so good is we don't make .277 bullets for any other cartridge, the only other is the 270 Weatherby and its running exact same bullets. There is just not enough market to invest in a different jacket die. In a .308 caliber that is tougher, if we make a run of 308win and a run of 300 Win Mags we can use the same bullet jacket and just tweak the formula of the lead hardness with mixture or temp control. or switch dies to make changes to the jacket. However when we just sell boxed bullets its normally middle of the road hardness and jacket design. Because we don't know what velocity it will be used." (The same way know one will know how far away an animal may be, rh) "The .270 shines" he said because every .277 bullet is made to fit the velocity window of that cartridge as exactly, because its the biggest seller by 99% in that diameter."
That always stuck with me if I'm choosing a caliber look for a stand out best seller in that diameter, as the chances of the bullets being made to match it's velocity window are much higher, at least in bulk bullets. Now granted that conversation was close to 20 years ago. all this may have changed a bit, but I still notice that you have to call and aske a bullet maker about the velocity window the bullet was designed for. They don't seem to want to put that on the box so to speak. Technology has changed too, and I bet those windows are much bigger now. And there are a lot more bullets, and calibers so that has probably different like everything else around me, but thought I would share...
Interesting info that I never even considered. I don’t know why I never thought about it seeing as how I load for .44 magnum as well as .44 special and there is certainly a gap in velocity between those two. Of course you still wind up with a big hole no matter the bullet so there’s that.
