Well Maverick I'll have to give you this one just on me being to lazy to research further. It had always been my under standing that the 270 and 280 were both necked down 30-06 derivatives.
No worries, it is a common misbelief, and most other cartridges in the .30-03 family are based on the '06 case length. FWIW the reasoning behind the longer case length is solely to prevent folks from chambering those cartridges in a .30-06Springfield (which is by far the most common derivative of the .30-03Govt.).Well Maverick I'll have to give you this one just on me being to lazy to research further.
It is hard to tell if you are serious or not, but they use the same case as one another (of course with a different sized neck), but different from most others. Most (if not all) other cartridges in the .30-03/.30-06 family are based upon the .30-06 case length (2.484in. vs 2.530in.). These include, but are not limited to, the 6.5mm-06A-Square, .30-06Springfield, 8mm-06, .338-06A-Square, .35Whelen, and .375Whelen.so then, are we saying, that if you were to go to the store, and open a box of 270's, and of 280's, that these both use different sized cartridges?
Both are based on the '03, but others are based on the '06. Therefore, it would be very easy to interchange the two, which could turn out bad (especially if using .280Rem. in a .270Win.) due to overpressure. OTOH inserting a .270Win. or .280Rem. in a .30-06 (et al) is all but impossible because of the case length (really the shoulder location).No , I was serious; it sounded like one was based on the .03, while the other was based on the .06
I'm writing that down.Some day I hope to be as helpful and informed as Maveric.
First, welcome to THR!Keepa said:I've shot deer and/or moose with 30-30 Win.,303 British, 30-06, 308 Win. ,270, 32-40, 44-40 25-20 etc.....but nothing seems to kill like my 280.
Some day I hope to be as helpful and informed as Maveric. I have learned a ton from this thread.
Right you are, just looked up the SAAMI specs. and I was incorrect about the .270Win. having a shoulder pushed forward (though it is based upon the .30-03Govt. cartridge), the .280Rem. OTOH does have the shoulder (and is also based upon the .30-03Govt./.270Win.). It is possible to chamber a .280Rem. in a .270Win. or .30-06Spfd, but doing so requires you to "crush" the shoulder (it is best to never underestimate folks).You might want to be a little careful there because Maveric has some of his facts backward. There is no way to chamber a .280 in either a .30-06 nor .270 chamber because the shoulder is too far forward.
