6mm ppc

[wvlongshot]

Only having started tinkering with 6ppc about 5 years ago I'm still in the learning curve. But to answer Frankm's question it's all about burn rates, how the bullets react to volumes and vibration of barrels. For some reason n133 loves lots of neck tension and lots of pressure. The more the merrier in most of the set ups. When things are right it makes your day. These guys have spent millions of dollars figuring out what works best for the game they play. Travel to a match, hotel rooms, lost wages from missing work, and assorted other costs make what is spent on brass very minor. Everyone is so competitive couple of thousandths knocks ya way down the list.
Other powders will work to shoot small aggs, but when you want to be on top don't be scared to feed that ppc.

wvlongshot, thanks for being a little more specific. Pressure and neck tension must go along well with N133 and 6 PPC.

Friend brought out his 22 PPC Cooper a couple months ago and was shooting a hot load of N133 with 55 grain Berger and it put 5 into a 3/8” continuous hole. He’s like me, not a competitor just a gun guy. That was an accurate rifle with nothing special, no custom rest just shooting off bulls bag and a slight tremor in his hands…! I d imagine the 6 PPC is even more forgiving/accurate.

Thx for response.

You obviously don’t shoot the 6ppc in competition. If you want to win, you must go where others are afraid! Nothing more needs to be said….
Your bullets will show you what they like.
It’s not always true, but most of the time, that’s the formula.

Remember, in competition, no one is shooting factory stuff. Everything is custom actions, hand swagged bullets and high end scopes. Brass, powder and primers are just expendables.

If you just want to punch holes in targets at your local range, don’t worry about loads that are used in competition.

What he said, but I'd throw Barrels in there also as expendables

Also, always remember that the 6PPC is a wildcat. Custom reamers, actions, ect.

There is no book for it.

I learned that the hard way~!

Over pressure according to who ?
The only thing I've had is the pockets wearing out. A good action will handle it, no problem.
I have 3 thou neck clearance on a loaded round.

The ppc was developed for competition. Some really shoot good. Some are a pita. Ive gotten lucky i guess with the 3 ive had.

A mtm funnel, its not pink it's mauve color !
With their 4" extension and a bunch of tapping i get 30.1 and I'm sure powder is crushed by the bullet. If i don't get it settled correct seating will be a pain.

I'll let the cat out of the bag on some with this. Their reamers make the case body a tad longer so it'll hold more powder.

My ppc is right at 2k rounds. The lands have moved 12 thou. I never changed the bto and it shoots great. It woke up & went from good to really good around 800 rounds. If i would have visited going from touch to jump myself at it's beginning I'd had a fantastic shooting rifle sooner.

My mind still wanders to the “why” …

I know I ve always had better accuracy loading belted magnums near max book loads but going beyond that with the competition shooters in PPC s , etc stirs my curiosity …

Some particular calibers - as you noted with the belted mags - have likes and dislikes - for whatever reason. The 6PPC likes to run hot. That is where the best performance typically thrives with that powder. I haven't competed in a long time now - but it used to be the majority of the guys shot that powder. (Post "T" powder and "pre" LT32, etc.)

Jackieschmit, not being a wise Azz but why is it that competition guys run such high pressure loads?? They could run an improved case, etc if it was velocity related but assuming that’s not reason. Is the ES, SD, etc more consistent when running 60-70K psi loads or what?? Do higher pressures just group better? Trying to broaden my knowledge; better understand the why??

We could care less about SD or ES. The only thing that counts in Short Range Benchrest, where the 6PPC excels, is how small of aggregates the Rifle is capable of shooting under match conditions.

There seems to be something magical about the capacity of the 6PPC case volume when coupled with a 65/68 grn match bullet. It’s not about velocity, it’s about a great tune, and keeping the Rifle in that great tune throughout the agg.

Messing with that case volume is going the wrong way. That case volume combined with elevated pressure just seems to work when looking for that magic sub .200 agging capability.

I do know shooters who shoot in a lower node. For myself, it just shoots more consistent at the elevated pressures.

Speedy mentioned in a couple videos with Erik Cortina, he loads 6ppc hot enough that the cases only last 1 shot. He's a pretty good shooter.

I've found the best way to save barrel wear is to leave it in the gun safe.

Just another consumable.

Yep! Very consumable! Accurate life of a 6PPC barrel is probably somewhere between 1-2 seconds….
How’s that new shoulder?

Custom actions, custom barrels, custom triggers, custom stocks, custom cases, custom bullets and more. Factory guns are not made to do this even though we have some "modified" guns doing this.

Speedy has a link to several documents that are from the creators of the 6PPC and destructive testing with a 40X Remington, to the point it was destroyed.

I am going to call BS on this. Link me to the video and tell me the time within it where he said that.

He said it and more than once. He was talking about having cases of Lapua brass and a large quantity of old Thunderbird powder. Now if you don’t believe it, then you must be delusional thinking I care what you think.

Even in the video above, he mentions he stayed at a mild charge and didn’t take it to destructive levels like he usually does.

Get your answer from the man himself @speedygonzalez

Great thanks. No pain.

I didn't believe it either. Until you said T powder. That would do it I'd imagine.

Don't think ruining cases with 1 shot would happen with N133.

The lot of N-133 I have, at around 30.9 grains on a 100 degree day..........the cases might not be ruined, if you like to hold the primers in the case with your fingers.

Speedy mentioned that he had 56-8lb jugs of IMR-8208S but he shoots N-133 because it's what his customers use. In another video he commented the brass was a consumable and tossed after some hot loads, didn't say the load but it had to be North of 30.6 grains.

He chooses to toss it.
I love 3rd party arguments.
My cousin's wife's husband said, did, told a friend....

Boyd , myself & many others have shot millions of rounds but yet the great speedy Trump's us all.
He's got a platform that's all.

I don't mean to knock the fellow, it's just he isn't a freakin god on every caliber out there.

Id personally like to see 30.8, n133 put in a6 ppc case and the bullet be seated to touch.

I have personally seen shooters at Phoenix, where 133 is very difficult to shoot unless you really pack it in there, use a fitted wooden dowel to tamp the powder down so the bullet would seat.

I’m not sure you can get enough 133 in a typical 6PPC case to blow anything up, but you can sure wreck the brass in two firings.

The old “T” was a lot faster. It basically had an entire different tuning approach than N133.

I know what Speedy shoots now because I loaded near him at The Bluebonnet. He and Mike Conry were working in the 30.0 to 30.3 grain range with 133.

I just got back from the WWCCA range a few minutes ago. I was playing around with seating depth on my Railgun. The load that worked the best for my bullets was greater than 30 grs. That’s hot, but not necessarily extreme for a custom everything, LOL!

At 200 yards my 4-shot groups were around .25-.35”
It was raining and temperature was around 78 degrees and humidity at 76%.

The point is, you shoot with whatever works the best.

Was that recently with the new Alpha brass, that's taking about 1 grain less for same velocity?
