Just wondering if the 6.5x284 was a potential candidate for the military's sniper rifle change from .308? Reading up, the norma will do everything the .300WM will do with very similar barrel life. Long actions ready to go! What say you?

I can not say for the 6.5x284 being even considered but from all I have read the 6.5 has a very short life. I have read that most people who use it get 750 to 1,000 shots Some get as high as 1,500. I have a 300WM and still looks good at almost 1k rds.

how do you figure the 6.5-284 will do everything a 300 win mag will? i highly doubt trajectory and distance to transonic are the only considerations for a cartridge that will be used against live targets.

Agreed. I'd bet the ability to not be effected by wind would hold much more weight than drop.

Just a question thrown out there. My current stick is a .300WM. I just picked up a 6.5x284 and have been reading opinions of the round. Just like to read what others have to say, as we all do here on the hide.
 
Re: why the .300....why not the 6.5x284

The 6.5x284 will equal and even surpass the 300WM *ballistically*... so shooting paper or steel it will perform similarly with less recoil and expense (in reloading) but perhaps made up in barrel life. One downside is smaller dust signature and movement on a plate to the point that it *might* be difficult to spot misses at extreme distances. Available 6.5mm pills may or may not perform well in the transonic region when compared to their heavier .30 cal. cousins.

The needs on a two-way range are more complicated. Not only must a round be able to get there with a reasonable amount of elevation, and buck wind well, it has to do a job once it arrives and the heavier 30 cal. projectile does that much better than the 33% lighter 6.5mm pills. 300 gr. .338 even more so.

I am sure you are all right about the kinetic energy playing a role. I guess that slipped my mind. I was more focused on the extra hole in the target making for a bad day for him and the two others having to carry him out, possibly removing them from the fight as well.
 
Re: why the .300....why not the 6.5x284

I think there are a couple of answers:
1) The larger diameter of the 30 caliber bullet leads to better terminal ballistic performance. The difference is notable, but on the counter side, the 6.5X55 Swede is used to take down moose today. Mortality can certainly be accomplished with a 6.5mm pill.
2) 30 caliber is a standard. Like it or not, for not only the US, but for her allies as well, 30 cal is a standard. We have a lot of 30 caliber barrels and 30 caliber bullets stockpiled. We can take existing barrels and simply rechamber them. For 6.5X284, the US would stand alone with 6.5mm. Others might convert, but 6.5 just isn't the standard.
3) Barrel life is not that great for the 6.5X284. As a matter of a fact, I would argue for terminal ballistics purposes and barrel life purposes, the original 284 WIN is superior to 6.5X284.

This is not to knock 6.5X284 at all. It will buck wind and punch paper or ring steel better than most. Barrel life is a huge concern because, as mentioned above. The folks who are getting >1,000 rounds out of them are setting back the barrel at 500 - 600 rounds.
