Okay fellow CGN'ers, one last cartridge comparison......:)
Let say running the Lapua with 130g JLK's or Bergers at 2900FPS Vs the
6XC running 115g Dtacs or JLK's? It seems to be difficult to find the exact
G1 and G7 BC's for all of these bullets?
I am trying to find a balance of ideal ballistics, bore life, lower component cost, and low recoil.(the holy grail!!:D)
Something of a step-up ballistically from the 6BR and lower recoil than a .284winchester....
Any CGN'er with experience with either of these cartridges would be great.
 
I know some folks tend to favour the 6XC out to 1,000 over the 6BR but I don't know much about the 6.5x45L.I think the case is about the same size as the XC so I would imagine both slightly slower speeds and a little more recoil.Probably negligible.Both would have less recoil than a .284.
 
I had the same question and after much consideration decided on a 6mm 1-7.5" twist barrel to shoot 6mm 115gr VLD.

Here is my basic analysis:
Diameter Weight Sectional density (G7 BC with I = 1.0)
.243" 105gr 0.254
.243" 115gr 0.278
.264" 130gr 0.266
.264 140gr 0.287

With 6XC, everyone is getting 3000fps with 115gr VLD and around 2300-2600 rounds of accurate barrel life.
6.5x47 Lapua can also get accurate 3000fps with a 130gr VLD but the 6mm 115gr VLD is a slightly better bullet.

6XC 115gr VLD
  • very accurate
  • long barrel life
  • very low recoil
  • lower bullet cost
  • can be used for small game hunting
  • can be used for medium game hunting
6.5x47 Lapua
  • very accurate
  • long barrel life
  • low recoil
  • slightly higher bullet cost
  • can be used for medium game hunting
  • can be used for large game hunting
My choice is 6mm since recoil is lower, bullets are cheaper, the rifle can be used for long range varminting and 6XC now has a proven track record.
The big advantage that a 6.5mm rifle has over a 6mm rifle is that a Barnes 130gr TSX or a Nolser 130gr Accubond is effective on large game.

I challenge those bore life estimates for the 6XC especially from the context of F class shooting. The 6BR has an ideal bore life of around 2000rds. There is no way a 6XC will do better.

I would suspect ideal bore life is around 1200 rds. Compare bore ratio to the 6.5's. Similar to the 260improved and Swede.

Depending on the powder, pressure used, it could be as erosive as the 6.5-284.

And any combo that uses a 7 twist is going to be fussier to tune then a slower twist and lighter for cal bullet.

Now if the goal is min of boulder, then bore life is much better.

So if the debate is between only these two options, I would suggest the 6.5X47L as the better choice.

If the goal is to compete in F Open with the 6.5X47L, you are leaving alot of change on the table and I would just as well go 6BR. It works

Fellow I shoot f class with uses a 6.5by47 Lapua with 130gr Bergers has a 30"1/8 Tru Flite. To shoot to 7 and 800m and uses a .284win at 900m and when winds are tough.
Man those 6.5 lapuas shoot, at 300m to 600m he does give up nothing to the 6mm br.
watch this video on a 6.5 /47 lapua not to many 6mm shoot much smaller at 400y

Part of the reason I just sold my 6.5x47mm Lapua was component costs. For the casual shooting I do, there's no way in Hell I have an interest in spending $130+ for 100 brass, regardless of how many rounds fired I can get out of it.

I built the rifle on a whim of fancy and never took an interest in shooting it even once. lol

6.5X47 Lapua now dominates 300 metre interntional position shooting and won its' first 600m BR match. It is, as requested ny the OP, a step up from the 6BR ballistically.

Hello Jerry, can you please give us your thoughts/opinions:D, on cartridges for F-Open? My "theory" is that there is two ways to go...the first one is one rifle for all distances, which of course will have obvious compromises,one way or the other. The second way to go is build two rifles, one in a smaller calibre for the "closer" distances and a larger calibre for the longer distances. I know you are using the .223 for FTR, but I would value you ideas for both of the rifle scenarios for F-Open.:)

Just make sure it's a Savage or your balls will fall off...:p
 
@lyle1 you are permitted to shoot pretty near anything in F/Open, and you can have a lot of fun doing it.

If you want to have a rifle capable of winning in F/Open against topnotch shooters, then you must build your rifle in a "no-compromises" manner. You must have the highest level of ballistic performance available to you (in practice this means something like a 6.5-.284 shooting 140-class bullets or a 7mm firing 180s), and your rifle must achieve accuracy as good as what all other other top shooters are getting (which can be scary-good accuracy). You CANNOT choose a mid-performance cartridge and figure you'll make up for it by reading the wind a bit better than the next guy - because the next guy is damned good too and he won't be leaving much if anything on the table to be picked up for "free".

If you want to to shoot F-Open for pure fun or you are willing to make some comfort/cost tradeoffs while shooting competitively, this can of course be loosened up and you can and should shoot whatever you'll find the most fun.

Glad I have been winning with the Savage. Wife would not be too happy otherwise.:stirthepot2:

Being in Canada, we have this wonderful opportunity to shoot F class from 300m to 900m. Most places think of F class as a 800 to 1200yds sport and size their cartridge appropriately.

SO you need to decide how far you want to shoot and the type of conditions you will likely face.

Due to cost and recoil, there are some shooters who are specialising their gear to the distance they compete in. The 6BR is one of the most popular short mid range options, although I have seen 6BR's kick everyones butt in a hurricane at 900m.

Then a larger boomer for the longer distances or when conditions get ugly.

BUT that also costs a lot of money.

When I was shooting in Open, I went with the 6.5 Mystic/260 AI. With 140gr Bergers, I was pretty much the same performance as the 6.5-284 w almost 50% more bore life. Recoil was as high as I could handle.

It shot well enough to help me win at both short and moderate distances. Makes a nice compromise.

In F Open, there really is no one right answer and the winning combo is changing all the time.

See how deep your pockets are and build accordingly.

I agree with Daniel,
6.5x47L will make a good short/midrange F-Open round. For that range the simple 6BR rules. If you want to be competitive at long range consider bigger 6.5's or 7mm. You will get clobbered by many good wind readers who use these calibers. The difference in the agg is usually 1 point or a few V's in Open.

Jerry always has some good points, spend as much money as you think you will need. If two rifles will put you on top of your game then come on out and try, IMHO get or build a 6BR use it till you get sick of it then go crazy, the custom 6BR I built has taken me to the next level of shooting in F-Open and with any luck and guidance from some of the best shooters out there I will one day become one. In so few of words...BEWARE OF THE MAN WITH ONE GUN, FOR HE WILL KNOW HOW TO USE IT.
