Re: 6.5x284 Throat Burner
Once you get past 3K fps, barrel life will show a sharper decline...Regardless of what caliber it is. Which is partially why the .308 Win lasts damn-near forever. That, and it has large bore with a small case capacity.
The smaller the bore, with the larger the case, the faster the bullet...Usually tends to burn out barrels faster than a big bore with a large case.
For example 2 calibers with the same case... 7mm RUM and .338 RUM. The .338 RUM will get significantly better barrel life over the 7mm RUM because it is #1 slower, and #2 has a larger bore diameter for the gasses to pressurize in and push the bullet down, so they're not quite as concentrated.
Yes, the 6.5-284 is a throat burner. You're talking about necking down a .284 WinMag to a smaller diameter bullet, that is faster and a smaller diameter bore for more powder to burn in... Which will equal a longer and more concentrated flame (hotter) coming out of the case onto the throat, propelling the bullet at higher speeds. No matter what caliber, if this is the scenario, it's gonna burn throats.
If you want a 6.5 caliber that's not such a bad throat burner, but gets good velocity, look into the .260 Rem Ackley Improved.
