6.5x55 vs 6.5-284
 

100 FPS is that all there is to this?

RE: 6.5x55 vs 6.5-284
 

I didnt reallize this either oldelk. After looking at reloadersnest thats about it 100-200 fps. Powder capcity looks to be about the same...


6.5-06 thumps it fps wise...especially with heavier bullets...

RE: 6.5x55 vs 6.5-284
 

That's actually verysuprising to me. The parent case for both (284 win and 30-06) have nearly identical volume- I've measured the difference myself and only found that the 30-06 case only holds about 4grains more water- and that can be attributed to the much longer neck on the 30-06 case not to mention that it hasn't been necked down yet.

RE: 6.5x55 vs 6.5-284
 

This round 6.5x55 has got to be the most overlooked round ever put out at least in this country.

RE: 6.5x55 vs 6.5-284
 

I get a little over 2700 fps using a max load of RL-22 (47gr)and a 140gr bullet out of a 29" barreled swedish mauser, you can load another full grain of the same powder in a stronger action, but the velocity gain isn't much. A 6.5x284 from all accounts pushes the 140 gr bullets around 3000 fps.

RE: 6.5x55 vs 6.5-284
 

I am going by my Nosler manual and comparing a 140 grain bullet and there was 100 fps. 2900vs 3000 ..... I have to look this manual over again when I get home.


Ok I looked at Nosler number 5 at home and the max speed for the 6.5x55 with a 140 was 2785 vs 2925 for the 6.5-284

RE: 6.5x55 vs 6.5-284
 

The only two things that I see 'wrong' with it is:
-A nonstandard rim size
-Too long for a short action, needs a full length action.

I'd still take a 6.5x55 over a .260 rem any day.

RE: 6.5x55 vs 6.5-284
 

Agreed. And yet over the pond it's incredibly popular.

RE: 6.5x55 vs 6.5-284
 

Its probably possible with a Nosler partition- in my experience, they have a very short full diameter bearing surface, while the full diameter bearing surface on the SMKs that I normally shoot arequite long. A different powder might give a bit more velocity in the 6.5x55 as well- I use RL-22 because its known to be one of the best powders for accuracy in the cartrigde, but its a very slow burning powder relative to the case size.

RE: 6.5x55 vs 6.5-284
 

In a modern and high pressure action I think that the 6.5 X 55 is capable of much more than many manuals give it credit for.
I have a stable of Swedes', but am reluctant to load them much more than slightlyover the middle of the road recommendations. Course, they perform so well there is little reason to try to push it and risk injuring my brass or actions.
Does anybody out there have some real life experience handloading a 6.5 X 55 in a high pressure action? I'd really like to see it's top end practical limits.

RE: 6.5x55 vs 6.5-284
 

I agree 8mm, We are comparing apples 2 oranges here.

Oldelkhunter 6.55 is a swedish round by the way not an american round, but I agree, unappreciated.

I am well aware of where it comes from:D put out for sale in this country is what I meant. The one problem I see is MAG is not in the name.

RE: 6.5x55 vs 6.5-284
 

The comparison of the 6.5X55 vs the 6.5/284 is exactly the same as comparing the 6.5X55 OR 6.5X57mm with the 6.5 Remington Magnum or the 6.5/'06. The .284 Win case has the same capacity as the .30/'06 case, but in a shorter, fatter container. It is prized for its accuracy potential, not its' ability to produce high velocities! There is no reason why the 6.5X55 or the 6.5X57 would not be just as good, except for the need to use a longer action for the latter two rounds.

My favorite moose relaxer 6.5X55 with 160gr Hornadys+ 42 gr IMR 4350.Works well with N-204,RE-22 and IMR 4350 as well.........................Harold

RE: 6.5x55 vs 6.5-284
 

To take full advantage of the 6.5x284, you will need to use a long action. If used in a short action, the OAL is going to restrict you when using the longer 140+gr bullets. Bullets will need to be seated deeper, thus reducing case capacity.

RE: 6.5x55 vs 6.5-284
 

is the 6.5x55 commercially available? isn't the 6.5-284 still purely a wildcat? though semi popular? if both were wildcats I'd pick the 6.5-284, but if the other is factory loaded, that would be a big influence, but i know many load the 6.5-284 for 1000yd benchrest......if both are known for accuracy and the x55 is factory loaded again be a big plus IMO. otherwise id take the -284 sine I hear more about it.

RE: 6.5x55 vs 6.5-284
 

6.5X55 is commercially available but I don't think there are many offerings. I've never seen 6.5-284 ammo in any of my catalogs. I think you can get commercially loaded ammunition for it, but only from specialty companies. I know you can buy virgin 6.5-284 brass though.

That's what I took my Moose with in 1995........Ruger M77 6.5mmSwede and 156 gr Norma"Alaska"

RE: 6.5x55 vs 6.5-284
 

Now this is just on cheaperthandirt.com but, lets see they have remington, winchester, federal, hornady, wolf and a few others, yep it's available, but most sporting goods stores aren't going to carry it.

RE: 6.5x55 vs 6.5-284
 

The Gun Store that I bought the Norma carry it, but at $45 a box of 20.:)
