6PPC VS 6mmBR Opinions on Accuracy

Bill Norris

Bill Norris

Back in the Day
I've read and also been told by a couple of shooters that the 6PPC will produce better accuracy at 100 - 200 yds. than the 6mmBR, but the 6mmBR will produce better accuracy at 300 yds. and beyond than the 6PPC. Is this pretty much the rule of thumb by most or is it a matter of personal opinion ? I know twist rate and bullet weight will play it's part.
 
Explain it to me like I'm 8yrs old


How can you be more accurate at long range than short range?



Seems counter intuitive.



Dont you have to start right, to stay right?
 
Man, you have an inquiring mind and are in for a lot of reading? I am sure you are wondering if 6ppc is more accurate at 100 than 6br, then why would a smaller ppc (or something other cartridge) not be more accurate than the 6ppc?

Neat thing is these questions have all been answered. (Ask me how I know:confused:). When you get bored reading from the search function on this site, got to benchrest.com.

Great questions though. I could have save days in my life by asking or the way you did. Dusty’s answer is direct and to the point.

Yea I figured as much Ccrider. It's just fantastic that there is so much knowledge from so many of these dyed in the wool and seasoned shooters. Nice to read the different answers and compare the notes. I'll never be a B R shooter but I sure love learning about accuracy and what it takes to get there.

After carefully studying some writings I found and to me makes total sense there is at least one answer or one set of circumstances that will state "NO" to the above question (Don't you have to start right, to stay right?) A very long heavy bullet such as a VLD type shot from a barrel with (not enough twist) may not be as stable at 100 yds. as it would be at 200 yds. Therefore the “apparent” group size may be larger at 100 yds. than 200 yds.
 
It depends on your discipline. PPC's win the most but then again, virtually every gun in a short range group match is a 6ppc. Very little chance of anything else winning if that's all that's there.

Nothing wrong with a ppc...very excellent cartridge!

If you research UBR, which is short range caliber neutral score shooting, you'll actually find a good and pretty even mix of what wins. It speaks volumes about how well other cartridges, such as a 6BR can do against ppc's side by side with the best shooters in the world shooting both.

Realistically, there's very little if any difference, all else being equal. The PPC and 30BR have their places, no doubt and both are excellent! Both also have a cult like following to support their position and the winningest cartridges in their respective disciplines.

I shoot a 6 Grendel(right between a ppc and br) in UBR score and won a National Championship with it against PPC's and BR's, both 6mm and 30's. But don't overlook the 22's either, like a 220 beggs or 22ppc derivative. They are very competitive as well.

You're asking an age old question where each has a following that truly believe theirs is best. As long as you realize that responses are heavily biased in large part due to what everyone is using in their respective game and their respective successes, you'll likely find that good bullets, barrels and shooters are what wins head to head.
 
For this kind of wondering, it's best to move past anomalies and look at the aggregates.
Overall, the underbores 6PPC and 30br dominate at point blank ranges.

Is there a dominant underbore at longer ranges? Or, will there be?
I don't think so, because the attribute likely squares in difficulty with growing cartridge area and longer distances.
For instance, a mid range equivalent underbore might be something like a 7x47L, running mid-weight custom bullets with ~85Kpsi loads. Cases abused so would only last ~5 loadings (like PPC), which is fine for some I guess, but viable & reliable extractions would take build adjustments that currently don't exist. And there would need to be a magic powder for this as well.
I don't see anyone cutting a path for it yet.

For long range, where BC seriously matters, it isn't ever going to happen.

Very well stated Mike! Especially your last paragraph. WD
 
There are several reasons why most agree the 6PPC will, on average, outdo the 6Br at 100. The biggest would probably be because of the bullet weight and the ability of the lighter 6ppc bullet to fully stabilize before target. The heavier bullets often don't go to sleep till beyond 100. That said, I know of a guy who set a world record shooting a 6PPC at 600 on a dead-calm day. The PPC is just as accurate at 600 - but the exterior ballistics put it at a big disadvantage when it comes to wind drift.

If you subscribe to the sleeping bullet theory theres a friend of mine over on benchrest central named “alinwa” that will pay you a lot of money to show him. It would be a good payday for you and very much worth your time- all expenses plus $10k i think now. Its a simple challenge nobody has took him up on for like 15yrs now. All you gotta do is show him a load that shoots a smaller moa at a farther distance than the larger moa at a closer distance. Pretty simple really if you believe it happens.
 
Thoughts and questions for no one in particular.

If a 6BR is as good or better than a PPC, why don’t we see more of them on the line in 100 and 200 yard BR competitions? You can get any twist rate you desire in a barrel so that opens up endless bullet style and weight possibilities to find the perfect sweet spot. Is it recoil? Something else? Or for that matter, why not more 22’s like a 220 Beggs? Recoil can’t possibly be an issue with a 22. How about a 20 Vartarg? I know that’s been tried. Maybe better bullets would push that to the top. I’d like nothing more if it advanced the game where in 5 or 10 years guys end up shooting high zero and low 1 aggs to win.

With all the testing and tweaking that has occurred and still occurs over many years in an effort for men to scratch their way to the top of the accuracy hill, the only conclusion I can reach is that the PPC is still the better choice as of this moment. If it wasn’t, that game would be dominated by a different caliber.

I get that there is a lot copycat and follow the leader stuff that goes on, but the counterpoint is that almost every guy out there is trying to beat everyone else on the line. It’s very competitive and the desire to win is great, so there is more to this than simply copycat. If a guy could win week in and week out with a slingshot that’s what he’d use.

Myself, I’ve considered campaigning a LV 30BR because that cartridge shoots really small and has been easier for me to tune than a PPC. It’s been done before, so it’s not ground breaking. The cited downside is always recoil over the course of a two gun agg.

I’m long on thought processes but short on experience, so think of this what you will. It’s thought provoking stuff for my little brain on a cold Saturday morning.
