30 BR rim to 6 PPC rim

John you just about have to grind one which isn't easy without a toold grinder.

Depending on the action, all you might have to do is cut the rim diameter down. Nick Marino did this with a PPC bolt faced Farley and it works fine. ......jackie
 
I've been doing it for several years. Go to a tool grinding shop. Take a ppc case and a br case and tell them what you want. They can grind a tool for you.

John,
Jackie Schmidt is right. Mine works fine with about a .010 cut off the rim & nothing in the groove. It makes me think that enlarging the bolt face that much might even be the better solution.

I ground this thing myself. For a Remington style extractor you need to cut about .028" off the rim. The groove on my cases measures app .385". I cut the rim in three passes with the cut going towards the chuck. Then I plunge the groove. Once you do a few cases you find out the number on the dial that you need to go to and it goes pretty quick. I have to watch out that the case doesn't back out of the Wilson case holder when doing the plunge cut. I also have to pay attention to not reduce the thickness of the rim.

The last process is to take a file and make sure there is no burr on the front face of the rim while still leaving it square edged and then use the file to add the chamfer on the backside of the rim to help the extractor pop over easily.

Part of the requirement for the groove diameter is making sure the cases fit your reloading press's shellholder.

I use a long brass rod through the spindle to knock the case out of the case holder. On the left I center the rod with the spider. After knocking the case loose I use a dial caliper to verify groove dia, rim dia and rim thickness.

You could use a cartridge that fits your boltface. The 30 Major and 30 ppc have proven themselves able to win against the BR case and will fit your ppc bolt.FWIW---Mike Ezell

Mike, just curious. What type of 30BR is that. The case face to shoulder is about .060 short, as well as the overall length........jackie

I noticed that too, and I don't know how it's that way, but part of it is that the tape is on it's end. That makes up for most of it and it looks like an unfired piece of brass too. Someone else did the picture. The OAL should be basically the same with all three and the base to shoulder length for the BR and PPC should be the same with the 30 Major base to shoulder being .070" longer than either of the other two. Good eye.--Mike Ezell
 
I had a cutter ground and the guy clipped me $50. for doing it. He said he had an hour into it and I believe he did.
 
Something wrong with that picture of the 3 cases. Either the 30BR is too short or the 30ppc is too long. Base to shoulder length is the same on both cases. At least as per the cartridge diagrams I looked at.

Tapes are designed to be used measuring from their ends just like in the pic.
 
For tools like this, starting with a 1/8" bit makes grinding easier - less steel to remove. Just put an angle on the left side of the bit.

Is this better? I don't have a camera that I can make take good closeups with the detail that is shown in the other pic. That's why I had a friend take that one. As I said, I noticed the BR case looked short but I don't know why. The PPC and BR shoulder starts at the same height. The 30 Major is .070 higher. Trim length is about the same for all three depending on reamer design.

Tape measures are carpentry tools and I'm not a carpenter, but the one I have beside me measures about .040"-.050" longer on end than line to line. I guess that's why they are carpentry tools and not used for precision work.---Mike

Mike,
The rivets attaching the chrome piece to the end of the tape ride in slots so that the chrome piece slides back and forth for accuracy in both inside and outside measurements. Usually they are pretty loose, but yours might be stuck in one position. Good to "thirty twoths," as my Grandpa used to say.:)

Cheers,
Keith
 
There is nothing wrong with the tape, that 30BR case is simply (about) .060 too short. Maybe it's a 30BR Tall Dog. I am real curious as to what someone had up their sleeve. What is the origion of that originol photo. ..........jackie
 
Kinda off the subject but will a 30x47L have the inherit accuracy the 30br does? Just something i always wondered. I know why guys use them in there hunter rig and i have seen some really impressive scores shot with that chambering but will they shoot groups like a 30br will? Lee
 
Skeet, there is no doubt that the chamberings that are used in the HBR Class are capable of phenominol accuracy. Probably for the same reason that the 30BR is. That being, great bullets, great barrels, and great components.

Of course, the recoil is more substantial, heck, we complain about a 30BR that loads 34.5 grns of powder at 10.5 pounds being a handfull. Those HBR Guys shoot 44 grns of powder in a 10 pound Rifle, usually with a bullet that weighs 15 grns more.

But, you know how accurate a 30BR can be. There are, realistically, just a few chamberings that will shoot at that level. The 6PPC, 22PPC Short, 222 Rem. Maybe a 25 BR. The only way to see if a 30x47 will stand toe to toe is build a good HV on one, and see.........jackie

I took that picture. The 30BR case in the picture was given to me by Joe Jarrell. It's made from a Remington 7BR case. Beyond that, I haven't a clue.
