6BR vs 6/6.5x47 L ?

[65BR]

Have a Stiller Predator action. Use expected, a sporter/perhaps heavy bbl-varmint taper, for paper- varmints- and deer, MOSTLY under 400yd, possible up to 500-600 on a rare shot in the field, but try setting up to not shoot that far, often under 250yd. ,killed one deer w/6BR at 400-double lung/exit with 105 amax so I am comfortable w/the BR that far).

Looking at doing a 22-24" bbl.

IS it worth losing bbl life to gain 200 fps for my ranges?

What about the 'donut' on 6/6.5x47 L brass? Is it there?

I do have 300 BR cases now, dies, and plenty 6mm bullets.....

And lastly, Can a BR chamber later be reamed to 6x47?

What would you do? Thanks guys.

Yes, you can ream a 6BR chamber out to 6x47 afterwards.

I would say that since you are only shooting short range, and in reality, even if you can push the bullet 200 fps faster with the 6x47, the varmint/deer will not know the difference. Plus from what I have seen,,I shot a 6-250 - like a 6BR run in deep - which is .044" longer than a 6XC in the body and thus more engine area than even the 6x47) the 105's like it around 2950 to 3060 in my barrel and the little 6BR can make the 2950 mark and will last slightly long, using less powder, 31g vs 39g.

Kodiak, I think I made my decision, the latest report I read, a 6x47 was doing 2850 for mild accurate load with 105s. Looks like another 6BR and the option for later to ream to 6x47 if I want to......

My 6x47L reamer did not clean up a 6br chamber as good as it should have so I set the barrel back to clean it up like it should be......
A different reamer may have cleaned it up better, I used a Kiff reamer on mine..

Good to know for the future, thanks. Might stretch bbl life.

Don't rule out a 6BR Improved,ie;Dasher/BRX etc).Have xlnt barrel life and are very accurate, plus you can push the velocity 3050-3100fps if you need to.

6x47 will do 3150 easy with a 30" tube...

For your case, the 6x47 Lap is not worth the hassle over the 6BR,to 600yds). Also, you wont see the advantage is much with the short barrel.

I'm guessing you'll have to knock a thread off the BR chamber to ream to 6x47 right?,6BR shoulder diameter) but I have not actually mic'd them yet...
