Does anyone know the difference ?
Are the case dimensions the same? (chamber)
My buddy has a 6mm PPC being built, its been a while and he hasn't been in a hurry so we,re unsure how far production has gone on.
Now were thinging that 6mmBR is the way to go as he wants to use it for longer range. He already has a short range tack driver.

any help would be great here.

Thanks

Mike.
 
If you want to compete in short range Benchrest the 6mmPPC is King of the hill... and along with that is a lot of brass prep and special dies and a considerable amount of work...

The 6mm BR (Lapua) when chambered with a no neck turn reamer will be so much easier to use and higher velocity and better at long range...

The cases are completely different, including the bolt face... the PPC case is a bastard size.... the 6mmBR is a standard .308 bolt face... both use small rifle primers..
 
6PPC is the undisputed most accurate catridge going out to 200. As stated, it is a cartidge and bolt face all its own, usually from 220 Russian or the 7.62X39 brass. PPC BR shooters use lighter bullets with loose twists.

6BR is designed for use with bullets out to 107 or even 115 grains and is a tack driver out to 1000 metres. It can be highly accurate using Lapua brass right out of the box.

If you already have something for short range, forget the 6PPC. It gives superb results, but takes lots and lots of work.
 
"...or the 7.62X39 brass..." Nope. .220 Russian only.
"...Now were thinging..." What? If your buddy decides to change his mind about what chambering he wants, in mid-build, his smithy will likely have to put the whole project on a back burner. If he's already purchased the barrel, reamers etc, your buddy will be paying for those twice.
 
I am not

the expert here but I can tell you that the PPC versus the BR is not comparing apples to apples. They are both probably the most sccurate cartridges out there but the PPC out to 200 and the BR beyond that out to 1000. The BR will suffer in the wind to the larger 6.5's or 30 cals. When I say larger I would say the 6.5x284 and the 30 cals in the 300 Win Mag case capacity and higher. There are those that will tell you the PPC is good out to 600 but from what I have read and heard it is just slightly lacking. Less powder than can be stuffed into the case.

The 6BR has really been shining in the 600 yard circles. There is a man by the name of Terry Brady down south who has been shooting some AMAZING groups with his 6BR's at 600 yards. There have been great groups shot out to 1000 along with records being set.

I would say decide how far your shooting will done 90% of the time.

If shortrange and you have the equipment the PPC is not that bad. A little more work in brass prep but not bad. Basically just neck turning to fit the tight chambers and go to town. The tolerences for the PPC to work best are very tight so it is not very good for field work. Pressures are very extreme in the 65-70,000 range. Best left to the bench only.

I do see the difference in performance between the 2 cartridges and I have only had my PPC for 2 weeks. They are not built off of the same platforms but the PPC is definately more consistent.

If your going to shoot further go with a 6BR with a .271 or .272 no turn neck. Lapua brass, 8 twist barrel and shoot the 105- 107 bullets on top of VV135 or 140, Varget, CCI 450 primers and go to town.

You will have years of enjoyment out of the 6BR with light recoil shooting out to 1000 yards. None of this bone crunching recoil from the larger calibers. Yes there are brakes out there for that purpose but if you ever decide you wanted to shoot a real match, sorry no brakes.
 
While you can make 6PPC from 7.62x39, the resulting cartridge would not use the small rifle primer which was considered to be important when the PPC was designed.
The 6BR was designed as Remington's answer to the 6PPC. Original brass was provided as 308 brass with a small primer pocket and the shooter got to reform this to 6 or 22 BR. The brass was headstamped "22 BR". The chamber dimensions were changed slightly at some point and the cartridge neck was lengthened by .050". Jim Stekl won the super shoot grand agg using a 22 BR 40x and a 6 BR built by Fred Sinclair, if I remember right. This was around 1980.
The difficulty in forming brass for the BR practically guaranteed the success of the PPC. If Lapua brass had been available in 1980, the BR might well have been much more common at short range matches today.
The 6BR capacity is a bit greater than that of the PPC which means it (a) does not work quite as well at short range and (b) handles heavy bullets and long range a bit better. I presently have 6BR's set up for both disciplines and they both work well. Nonetheless, I would never recommend anything but the PPC for a serious short range rifle. Regards, Bill.
 
Just as a matter of interest the 6BR was designed by a Canadian not Remington. I worked with Alan King, (the designer) on the 6X39 in 1977 & 1978, (The Handloaders Manual of Cartridge Conversions, by John J. Donnelly) page 742. Alan won Super Shoot 1976, ( The only Canadian to do so) using a .308 in Unlimited and HV. In those years SS use to change every year. 1977 was to be HV and LV. Alan built a .308 LV to compete in 1977 and shot it in 1 match in Stittsville for 2 days and that was the end of that. He then, along with a gunsmith named Ferguson designed the 6X39. The idea was to have a 6mm cartridge that would have .308 ballistics and of course, 6mm recoil. To skip a couple of years Jim Stelke of Remington aquired the rights to the 6X39 which we all know now as the 6BR. I could go a lot more in depth but you would find it boring.
 
Thanks guys

Thanks guys for your advice here and info.
Last night we got a call back from our gunsmith/barrell maker. If you,ve ever owned one of this guys barrells or shot against someone with one you,ll probably remember the name Rob Mc Lellan. Rob called and we asked if Andy's 6 PPC was done or still in progress, did we still have time to change it to a 6 BR ? Andy already owns two other of Robs rifles a Remington XR 100 in .223 that rob re barrelled clened up the bolt and helped mount a 6oz. trigger to, this thing shoots absolutely fantastic at shorter ranges. Andy has a Remington .308 Rob built again with the 6oz trigger, and the 6mm has been in progress for a while now.
Anyways Rob said it wasn't going to be a prob. as he had other PPC rifles on order that were in line behind Andy so he,d give the next guy andy's barrell and he'd have a new one ready in about two weeks for Andy. He's gonna make it a 1-8 twist and 30 " Long, says it,ll throw 107gr. sierras quite nice he says it,ll be set up for Lapua's.

Can't wait to see it.

BTW, Andy had bought another Rem. to have Rob build a 6.5X284 before we asked about the 6 br. He's decided to wait a bit but still plans to make that one too.

Hey Bill

Please continue on. I enjoy hearing how Canadians have impacted the firearms community. It is nice to know that something as popular and accurate as the 6mmbr was influnced or designed by a Canuck.
I recently read an article in PS comparing the Rem Ultra Mag to a former Canadian design "Imperial Magnum" series produced by the NSSA.
