6.5BPC aka 6.5 Grendel!

Well guys, my smithy finally came clean on his 6.5BPC chambering, it seems he is tightening up the chamber spec's on the Grendel reamer used for gas guns and to save confusion, is calling it the 6.5BPC. Don't know about how much confusion he is saving, cuz I was plenty confused,Just a "Mountain William" from the coal mining area of PA, Cameron County). Hope I didn't have many of you good folks scratching your heads along with me.

Good question! I have it mounted in a select grade factory 700BDL stock, and will also have .260AI and 308 switch barrels for it. Would like to see how it does on chucks and deer, also see if it will be accurate enough to go to 1000 yds. I have neck and back problems so I'm not sure if I can shoot F class or not, will give it a go and see what happens.

Well I'm not sure on the FPS achievable with the 6.5x47 versus powder charge compared to the Grendel using the same bullets. Do you have some load data for the 6.5x47, and say a 142gr. bullet?
 
Congrats on your choice of the 6.5 Borden-Palmisano Cartridge otherwise known as the 6.5 BPC. It was developed to use 80 to 85 grains bullets which we are in dire need of.

Jim,

You mean like the 81s and 87s that I am currently buying from Mr. Cauterucio to shoot in my Grendel BR rig?? :D,BTW - it has a 14 twist Krieger) I would agree, however, that another supplier would sure make me feel a bit better about the whole deal. Dont get me wrong, Bob is great and his bullets really shoot well. My concern is just about what would happen if he retired, or this thing takes off and he gets too backed up for orders.

I sure am excited to hear of others interested in shooting a similar cartridge. I have been basically going it alone for the past year with this idea. Feel free to contact me if you have any questions about what I have been doing.

OK guys, I'll bite. Can someone post a photo of the 6.5 BPC? I'd like to see what exactly can be done to that tiny Grendl case that would result in something that revolutionary.:confused:

Ray,

I am shooting a match version of the Grendel case, but it is still just that. I would be happy to post pics, but if you have seen a Grendel case, you have basically seen what I am shooting...

Thanks for the clarification. So the BPC is really a custom chamber, not a cartridge, and is nothing more than a tight neck, tight butt, Grendl?

So why the fancy name?

More appropriately--why the fancy name 6.5 Grendel for a 6 PPC,Pindell Palmisano cartridge) necked up to 6.5 and blown forward a little--nothing revolutionary for sure......

I think it's appropriate when a case is substantially changed from one shape to another, to give it a new name. For example, the 22PPC is really a 220 Russian with a small change to the shoulder and body taper but I don't think anyone would argue that it should continue to be called a 220 Russian. On the other hand, if I chamber a rifle with a tight neck and butt, but still for a 22 PPC, should I call the cartridge a 224 RTM? It wouldn't be long before we run out of monikers. Being a certifiable wildcatter myself I certainly will not begrudge anyone giving his pet cartridge any name he wants but if it is really nothing more nor less than an existing commercially produced case, it may bolster his vanity but does nothing for the poor soul newbies trying to sort everything out. JMHO

Here is a picture - plane Jane 6.5 Grendel in the middle.

While the 6.5 GRENDL may be a new cartridge, the design and shape certainly aren't. Here's a photo of 3 cartridges almost identical in shape. On the left is a 6 FIREWALKER, a Benchrest cartridge that I shot in the last Century. It's a PPC 40 degree improved, if you will. There are still a shooter or two who use it albeit with their own name for it. Center is the 6.5 GRENDL. On the right is a wildcat that I played with more than 10 years ago. It's a FIRWALKER expanded to 6.5mm with a 60 degree shoulder. I don't have a name for it but I suppose it could be called a 6.5/60 FW.

So, there's really never anything new except for the monikers.

OK Guys! Gee, I started out trying to get some clarification/substantive advice on the 6.5 BPC, and ended up starting a donnybrook. Does it really matter "who shot Jane", in the end aren't we all here to exchange information and assist other shooters so that we can expand the base of the sport we all enjoy so much? I would like to thank Mark Walker and Jim Borden for their help, and all the rest who took the time to help educate a novice distance shooter. I have never shot at ranges exceeding 300 yds., but am most interested in paper punching, dropping some steel & an occasional Groundhog at extended range. I'm hoping that this cartridge will fill the bill and fit in between my powder hog 260AI, and my barrel burning 22-250.
May you all shoot record groups, and enjoy the smell of burnt powder more than a t-bone on the grill!

Best of the best to all,
Jim Berry
