I have a .260 in a Bolt gun and trying to decide between the 264lbc and 6.8. They both have their merits...........My local gun shop stocks 6.8 by several mfg and only one batch of 264 (6.5) If choosing long distance, wouldnt the 264LBC be the better choice over 6.8SPC? If I read the ballistics charts correctly, 264LBC looks like it will stay supersonic longer than 6.8SPC.

4-500 yards isn't really long range in my mind, but if you are looking at staying with the AR15 platform I don't think you can beat the .264LBC. It'll reach out a lot farther than 4-500 yards with amazing accuracy with the right barrel.
If you are looking at the AR10 type platform, there are a whole lot of options, but you still can't beat the performance of the good ole .308 and you can find ammo if (I've done it, I know) you forget yours and you're a long way from home!

Hey Guys, I am very interested in Carl's new uppers (the ones you guys were talking about) I have only been to your Home page 3 times' Can I go there and see the new Upper that Carl has design? As anyone looked at the 6.5x47 Laupa?? One of my friend stuck that in my ear about a year ago but I didn't what to go with the AR 10 platform. I also have a OLy 243WSSM AR15 upper that I bought new and trying to get it tuned. Now that I have read this post, maybe my Grendel will be a shoot and sell? ?? If I could get a upper that was 6.5x47 L that will fit the AR 15 lower, I believe I would buy a single shot lower, in a long range rifle I shoot single shot only any way. Let me know, where to look at the web page to see Carl's new Upper. Thanks Greg

I had been looking at a 6mmAR from Alexander but I am now disabled and on a limited budget so I have decided on a 6x45 that I am going to build myself for about half the cost.

I want a 6mm. Period! Yeah, I've looked at the 6 x 45 but want just a bit more without going too extreme. Common (read inexpensive brass) components and readily available bullets.
I liked the idea of the 6 mm WOA and the 6 DTI but barrels of this nature seem to be out of sight. Like the 6.8 based cartridge idea. the 6mm LBc looks interesting but seems to be only available through BHW. This is okay but I don't appreciate the protracted wait for product.

Kind of like the Devil and the Deep Blue Sea!! My understanding is there aren't any WOA out there period and the DTI's are DTECH's world and MM up there is a busy man. I suspect that the 6.8X6 will be available before you could get one of the other two. The 243 LBC is a shooting machine. Easy to make brass for and every one that has been made recently has been shooting lights out. Consider that in your thoughts. The brass is a bit more expensive but with 300 pieces you should be GTG for a long time. That's only about $160.00 on sale and the dies are just good old 6 PPC's. Greg

Have you called Black Hole to inquire when they will have some 243 LBC barrels ready? I know they had a 20" on the shelf this morning. The 243 LBC IS only available through Black Hole because we are the ones who have done all the development with it. We don't own the exclusive rights to it.

The 243 LBC is a better choice. You have more options with longer bullets due to case length/neck. Also good 6.8 brass ain't cheap, is it. Think of it this way, you might pay only a tad more for the lapua but if you do not go too hot it will reload many more times making this cheaper and it is very consistent so this translates into accuracy that brings the big smile factor. I shoot 6x45 and 6.5BR but I had to shoot 6mm I would got with the grendel/LBC case. It is a no brainer. It is perfect for that, even better than 6.5. It is almost like the LBC doesn't want to be a 6.5 and does better in 6mm with longer barrels and 7mm in 18" barrels. Mike from DTI has a huge backlog. you are for a long wait there too.

Just what I needed. A little more nudge toward the 243 LBC. I know this is the way to go, as it is an awesome cartridge.

Good choice. Ask others that have experience with it here in this forum but for me a good cartrige option must have the capability to properly seat the best bullets and enough powder to do the job. Get a nice 22-24 incher and my take is that you will love that for long range. Bob Whitley has many things already figured out, just follow from there. Lots of knowledgeable people in this forum too. Cheers, E.
