6x55 swed?
- Thread starter Josh11
- Start date
Look up the 6mm Vais, it's a 6.5x55 Swede blown out and necked down to 6mm. Very similar to a 6mm-284 and 6mm Arch. If you can't find anything send me a pm I'll forward some articles and builds.
GoNavy,
A 6.5x47 will not come close to a 6.5x55 in a modern action. I have a 6.5x55 and it comes with in a half MOA of my 6.5x284 data at a 1000yds when loaded up with a 139.
The 6.5x47 has a hard time keeping up with a 260. I know, I have heard all the stories too. But in reality most 6.5x47 start blowing or flattening primers keeping up with the 260s.
I either have or have shot all the above mentioned calibers so I am speaking from experience and I am "NOT" trying to start a pie fight over the wonderful 6.5x47 but it is the weak sister of the 6.5 family.

I shoot the 6.5x55 in a Model 70 Win. set up as a tactical rig. A very forgiving cartridge, easily shoots under 1/2 MOA. I use Lapua 139 Scenars pushed by H4831, velocity is 2850 fps, no pressure, very consistent. I compete against .308 Win set ups, not really fair, given the ballistics. By the way, I agree, the 6.5x47 is best with 130gr. projectiles, it doesn't have the case capacity to push the 140's.
How good are the 6.5s on barrels? I know that the 6.5 284 is nasty on them, but what about 6.5x47 or 260 or 6.5 swed? I would most likely be shooting the 123s or so. Dont think ill be going up to the 140s. But who knows. Also on another note, how good are the 6x47s on barrels? Is the 6x47 bigger than 6xc?
The more powder pushed through a tiny hole, the faster the throat wears out. The 6.5x55 is much better on barrels than the 6.5x284. Another issue is high pressure, heavy bullet loads, especially with double based powders. Shoot lower pressure, single based powders and the barrel life will be greater. The 6mm cases are in order 6mmBR, 6mmDasher, 6x47, 6xc, 6mmSuperLR, .243Win., .243 Win.AI, 6mmRem., 6mmRemAI., I am sure there are more. These will burn out their barrels pretty much in that order.
Rhino always did well when the Bodine`s Prone League was still active. He recognized the value of glass with 1/8 min. adjustments (and how to better take advantage of same on the old target) as well as a firmer understanding of the later relay wind that was always a factor in the 1K matches.
You could do worse than the standard 6.5X55 Swede

Raptor,
"in a modern action"
Obviously your a reloader to the extreme.
Per the Lapua reloading manual:
260, N560, 44.1 grains, 139grain lapua, 2586
6.5X55, N560, 47.6 grains, 2746; my load
6.5X47, N540, 37.4, 2744. Note, 10 grains less powder!
The ideal bullet for the 6.5X47 is the 123 grain lapua or the 130 grain vld berger.
I shot the Swede for five years from 300 meters to 1000 yards.
With the 6.5x47, less powder, less recoil
By the way, I used the published reloading info from Lapua with success. After all, the 6.5X47 was their way of improving better scores over the 6BR. Their research is more believable overal.
It be slightly less in the 6.5 caliber for those of you who reload to the extreme, velocity. But, for me, accuracy "group", and shooters skills will come more quicker using 10 grains less powder.
Then again, if your and F'r, extreme is your game. No recoil issue.
Less powder, less recoil, more barrel life. You pay for what ya get.

GoNavy,
I agree with you 100% on the 123s or 130s being the ideal bullet for the 6.5x47 and also the 260s. I don't really feel either case is really large enough to really get the full advantage out of the 139 or 140 class bullets.
I went to the 6.5x55 in order to get better barrel life than either my 260 or 6.5x284. I hoped by using slow burning powder I would be able to still push the 139s to around 2750+ and get better barrel life than my 260 with the same bullet.
I don't push my loads to the "Extreme" either. I am more into the accuracy node. I said what I said because during my load development I had a good shooting load that "Did" shoot damn close to my 6.5x284 data. (Not the load I am using)
Right now I am shooting nearly the identical speed my 260 was with the 140s in my 6.5x55 which is what I wanted to do. The only problem is it loves H4350 and not the slower powders I wanted to shoot so time will tell on how it does for barrel life.
By the way your looking at two different powders for your load data on the 10grs difference so that may make some difference too. (560 vs 540)
The only point I was trying to make is that the 6.5x47 won't run with a 6.5x55 for velocity in a modern action if you want to load them to there full potential.
I just get tired of everyone saying how a 6.5x47 is faster than the 260 or 6.5x55s when thats not the case. (If you are loading all the rounds to there full potential.)

I was getting around 2300 rounds out of my 260s when I was doing tactical matches but they were pretty hard on barrels esp the Wyoming shoot in 100 degree temps and man on man shooting.
I would guess you could go an easy 3000 with no problems if you didn't get them to hot. I had one of mine set back at 1850rds and now have 2800+ through it and its shooting great.

28-30" for a match rifle. 2,900 fps is just on for 139-142gn bullets from most 30" tubes, but may be less depending on bore dimensions, what load groups best etc.
Depends what you mean by "fast enough to shoot 1000 yards". 6.5X47L with 140s (or even 123gn match bullets) will perform at 1,000yd being accurate and still easily supersonic at this range. Will it beat a 6.5-284, .284 Win, or 7mmWSM F-Class or prone rifle? Not unless the 6.5X47L shooter is a world-class judge of wind conditions.
Using Bryan Litz's G7 BCs and the Berger Bullets free PC ballistic program, the 1,000yd numbers are:
6.5X47L 139gn Lapua Scenar 2,850 fps MV .................... 1,436 fps / 76" drift
6.5X47L 140gn Berger VLD 2,850 fps MV ..................... 1,543 fps / 67" drift
6.5-284 Norma 140gn Berger BT L-R 3,050 fps MV .............. 1,652 fps / 62" drift
.284 Win 180gn Berger VLD 2,850 fps MV ...................... 1,623 fps / 60" drift
Wind drift is in a 10 mph 90-degree crosswind. Speed of sound is 1,122 fps at 59 degrees F; trans-sonic speed zone starts around 1,475 fps so 6.5X47L can stay above it at 1,000yd with a good combination.
Against that, the 6.5X47L produces less recoil and gives a much longer barrel life than 6.5-284 or 7mmWSM, don't know about .284W barrel life.
So, as always you pays your money and makes your choice. I suspect 6.5X47L may become THE 600yd F-Class cartridge before long, but it won't compete at 800-1,000 with the barrel-burners used by rich Open-Class shooters. So, it depends on what you plan to shoot in, at what ranges, and at what level of competition.
Oh, there is one other thing to note about this cartridge. Like 6BR, 6SM and 6PPC, the 6.5X47L uses the small rifle primer. This can limit loads and pressures depending on the action used and firing pin diameter usually requiring the Remington 700 pin to be turned down and the bolt face bushed for instance to run maximum loads without piercing primers. It's not a problem with custom single-shot actions from BAT, Lawton, Barnard, RPA etc. .260 Rem, 6.5-284N and 6.5X55mm use large size primers and are much more tolerant about bolt / pin dimensions
