True, but woofer is looking at a LW hunting rifle, not a bench gun, thus the hair-splitting.

My 6BR - last 26", 8t, ran 105s at 2850. Figure 8-12fps per 1" cut. BRX - 'ai' runs around 2950 in similar bbl. The 47 should run around 3,000-3050 in a 22-23" hunting rifle w/105s.

Above assumes safe accurate loads, not 'all out primer pocket loosening loads.'

Yea under those parameters I would take the 243AI there is not much much diffference unless your shooting high volume. I just debated im my mind what to chamber a new brux 6mm interrupted fluting sendero contour barrel in. I have reamers for 6x47, 6x284, and 243 and 243AI. I decded that I could not go wrong with 243AI. Now just to decide what action and stock to use. I am thinking just a trued 700 in a HS stock. I have decided to use the defiance action and McMillan HTG I had earmarked for this barrel with a Rock creek ABS that arrived the other day. My stable of 6mms is getting unmanageable. I think I am going 243AI with both but may change my mind and do one in 6x284.

what about mag length restrictions with the bigger 6's? any benefit to running the shorter BR cases or L? no fireforming is fun. i am not afraid to buy brass. just wondering if i am leaving anything on the table by wandering away from the 243...

thanks!

another thought. do these rules apply to the 6.5 also or the larger bullets eat up horsepower to the point that the benfits befall the 08' case?

thanks

I built mine for hunting. It has a ten twist barrel cut at 22". I shoot 85gr Sierra HPBT's and it is a tack driver. One downside is the lack of data. I have not used mine alot, but have killed four hogs with it. None took a step.

Yes, great round. Mine is built on Defiance Deviant action with 26in Bartlien barrel, MTU contour, 8 twist. Built it for long range. PRS. and sniper/tacticaL type matches.
Running 105 hybrids at 3080, shoots great, haven't tried to push them faster.
Pluses about it in my opinion:
1. Low rcoil
2 Redding makes the dies.
3. Simple to neck 6.5x47 brass down, just run thru 6x47 die and ready to load.
4. Short action,uses standard .473 bolt face.

I just chambered up one in a Savage action for OWL. I am waiting for Defiance to send me two actions to do two more. Suggestions on loads?

I'm using 39.6gr H4350. The guys that helped me with this told me to max at 40. The guy who's reamer was used to cut my chamber uses same load with a 107smk. I did my original load up when temps were in the 20's, waiting for some hot weather, 80's, before tweaking load.

I ended up with an almost identical 39.7 grains of H4350, which pushes an uncoated Berger 105 Hunting VLD to 3,020-3,040 out of a 23" barrel, on a 70 degree day in Tucson.

Through cartridge or build it's been a bit of fickle mistress. Partly because I had that "It's Lapua brass, it won't need any work" attitude I simply swaged the necks down in a 6BR die with about a .268 bushing. After disappointing trips to range I mic'd the necks and found them pretty significantly egg-shaped. I ended up setting the neck turner to skim about 2/3rds of the neck and my .270" loaded rounds in a .272" chamber now seem to offer less "WTF" shots in a group. This coupled with cutting down the originally 24" barrel to 23" seems to have it shooting more consistently, but nothing spectacular. I've tried hotter charges, different primers--nothing seems to be a magic combo for it.

Will spend more time with it, but for me it's been sort of a "shrug" chambering.

Took the 6x47L and a couple other rifles out for a run this afternoon. First decent day in what seems like forever to do some shooting/load testing - mid-60's, light 5-10mph wind at 90* to my shooting lane.

Had about 35 rounds with me loaded with H4350, 87gr VMax, and CCI-450s, with a 2.665 COAL. (Note: Berger manual shows 2.800" COAL with their 87/88gr bullet. The 87gr VMax, in my rifle at 2.665", was .010 off the lands.) Loads started at 39.0gr and went up in .3gr increments - 3 rounds of each load. All loads groups at 1" or less at 100yds, but the final load of 41.4gr/H4350 grouped at .368" with no signs of pressure. Of the remaining loads, the load of 39.6gr/H4350 grouped .524".

Oehler 35P clocked the 41.4gr load at an average 3124fps, 10ft from the muzzle. Got a PD trip coming up, and need to load a bunch, so I'm gonna stand pat with the 41.4gr load. I might possibly bump up the powder charge a little, and play with seating depth when I get back.

Shot the first 6x47L that I chambered this weekend. Shot 55s, 65s and 100s- 9 1/4 twist so no need to try the VLDs. I used Varget for the light bullets and 4451 & 100V for the 100s. This is a 24" featherweight barrel on a Savage so I didn't expect much for accuracy but it DEFINITELY is not up to 243 Winchester velocities. I went until I had definite pressure for each bullet and powder so I would have a baseline to work off of since there is almost no PUBLISHED data on this cartridge.

Wind was horrible so groups were not always great-even with the good rifles. If you guys are getting 243 velocities, you are also getting stratospheric pressures!

With that twist you might try the 95 SMK's, or TMK's. I had some promising groups with those, and a case stuffed with N160. Didn't chrony them, and they printed a bit lower on the page than other loads with 4350, but they did group---.3'ish

THis was just an experiment with a $30 ER Shaw barrel. I am still waitingfor actions to chamber with match grade barrels. Just noticed that velocities are not magical- about what you might expect with that much powder.

This rifle is going to be a coyote killer. ANy bullet will work

6.5x47L brass has been typically, wonderful; coupled with a small rifle primer has great potential for and efficient, accurate round. I have read several places where folks claim 243 Winchester velocities. Powder capacity is 6 or 7 grains less. Just not going to happen. I am still waiting to see what the accuracy side of it is. I shot a total of ONE group that all cases had the same powder charge. The rest were half grain increments to see the VELOCITY potential and try two new powders (to me). The rifle had a very well used, cheap-ass Simmons scope on it. Conditions were very blustery. I can't even begin to judge how well this particular rifle will shoot.

I am optimistic that the cartridge will be good to me. Not as much confidence in a $30 Shaw close-out barrel on an old Savage with a $30 scope.

Blue- there is lots of good data for the 6.5x47L, not so much for the version necked down to 6mm.

Dennis, the 6x47 I recently sold averaged 2956, 105 Amax over RL26, 22.75" barrel.

I checked my notes and my 243AI that I recently sold, averaged 3018, 105 Amax over RL22, 22.5" barrel.

My 243 donor for the AI above averaged 3005, 105 Amax over RL26, 24" barrel.

Out of a 22" barrel I believe it's a tie.

Rio,
I'm getting 3005 with 105's out of my 6mm Remington. I could push it more, but it shoots great as is.....
