What am I wanting here -- 6PPC Wildcat?

[Sniper338]

Left to right: 20 Vartarg, 6.5 Grendel, 6PPC, 6BR, 6BRXD, 30 BR...

I have an itch for something that's a 200 to 300 yard laser beam, stupid accurate, no recoil... smaller than a 6BR case capacity, but more than a fireball case. This leaves me with 220 Russian variants of Grendel cases, PPC etc... I like the neck length of the 6PPC, I dont want much more capacity than a 6 PPC, or the shoulder blown forward as much as the grendel....

Next I want a steeper shoulder than the 6PPC.. Ackley Improved, not much body taper... (like the 6 BRXD pictured)...

I'm dang near wanting a 6PPC Ackley Improved... steeper shoulder angle and straight body... but then shortening the case with the shoulder back .1000 or so... would be ideal.... basically take away the added case capacity of AI-ing the case... maybe shortening it is going too far...

What wildcats am I toying with here besides a 6PPCAI?

Why I want this? No big reason... I just want a stupid accurate little sharp shoulder straight wall case to shoot deer in the head with that looks cool and is fun to shoot with not much felt recoil at all...

If you would have read the post you would have known thats not an option for whats wanted. I have one.

No 22’s on there so why not a 22brai. Just an idea. I don’t have one but I think it would be cool.

Choot'em in the head ?

If you're good enough and disciplined enough for head shots,
just about anything you have there will do the job.

Kill the head and the body soon dies------think about all the
good pork that's the result of a 22 RF between the eyes.

You have a pleasant problem here, choose what you like
and knock some noggins.

I'm not set on caliber, just trying to find a cartridge case at this point. I'm 6mm or 25 cal probably. I dont have a quarter bore gun. But I dont want to hinder velocity too much either... a 25PPCAI sounds interesting though.


I looked into the grinch... its off the Grendel case though so I assume it still has the shoulder forward more than a PPC which I dont want.. trying to stay smaller than a Grendel case capacity.

Why not go with a 22 PPC, it is super accurate and plenty fast for your wants, and will kill anything you hit in the head, as you say.

The majority of thing I shoot in the head. Unless its going to the taxidermist. Shot a doe in the head with my 284 last weekend. Everything I got has done it easily... im just after a no recoil caliber more and more. Id 20 vartarg it, but I dont have a 20vt set up for hunting, its a bench only PD gun.

I'm not against a 22 caliber, but I'd still want the shoulder angle at 40 degrees and straight body taper...

6mm Brat. BR around .100 short, choose your neck length and shoulder angle. I'm not sure if there is a "standard" dimension here. You can do most anything your heart desires.
I personally give credence to the "turbulence point" theory so therefore like long necks and sharper shoulders. The .473 case will give you a greater selection of parent cases in case this all gets to be even worser than it is now for our components.
The PPC is a sexy little starting place, true, then massage the bejeebers outta the 7.62x39.
Nice to have choices, eh?

Do you want off-the-shelf dies, or are you prepared to dive into the custom world? I don't think there is an existing cartridge that meets your list. A call to JGS and Whidden is all it takes to make your dream a reality!

If you didn't mind all the work making brass, I've read nothing but amazing things about the 22 Waldog and have always been tempted to build one.

I absolutely love my 22BR for shooting at 300yards with 80 and 90gn bullets. It has been the easiest, most consistent shooting rifle I've ever worked with and has completely changed my perspective on what shooting small means. It has regularly popped off 0.5" groups at 300 yards and 5" at 1000, although I think that's more a reflection of my skill than the cartridge, because the ballistics are better than the 6BRA and I suspect a better shooter would get more from it at 1000. I've got a new barrel coming for it because at 1800 rounds it's started shooting more in the 1" range at 300.

I've only had to trim the brass once in 18 reloads, at maybe 10 reloads or so. If trimming is why you want a 40deg shoulder, it may not be worth the cost of custom everything to get it when 30deg shoulders grow so little in this size of case.

22 match bullets are also about 10 cents less each across the board compared to the 6mm match bullets. That adds up and means a 6mm shooter will always spend more, even if they get a lot more barrel life, which they don't.

If you AI a ppc case you take away the magic attributes it has. Go with a grinch or a plain grendel. Both great cases

So im looking at basically a 6-40 tyger here... thats pretty much nails what I'm thinking about...

Seems like it would be cool to mess around with for sure

With powders like LT30 and N130 a slightly less capacity than a standard ppc those faster powders might work really well

Howdy !

While the shoulder blow out to larger diam of AI cartridges adds capacity over the stock version of a case; the sharper shoulder angle of the AI version serves to decrease case capacity a bit.

Consider a wildcat chamber cut by running a 22-6mm Remington or a 6mm Remington reamer in "short ",
for a nominal .453" base diam . Parent brass would be .35 Remington. These wildcats would have both have base diam between that of a PPC-based case; and that of a .308Win-derivative case ( BR ).
Shoulder angle would be 26*, and neck lg longer than that of either a .22PPC or 6PPC. The shoulder angle and long neck of these wildcats would keep the powder combustion " turbulence point " ( that TAJ45 mentioned ) within the case' neck.

Case capacity of the above wildcat(s) would be a tad more than a .22PPC or a 6PPC, by nature of the generous powder space afforded by the wildcat's 26* shoulder area. The case would be LR primed, but ..... that is not a death sentence on attainable accuracy. I had trial formed a small batch of the 6mm-.35 Remington shortened wildcat mentioned above; in the past.

The .35 Rem based wildcat as mentioned above would not have the minimal case taper you elude to.
However, if the shoulder diam were blown out too; case capacity would eclipse that of a PPC by an even wider margin ..... perhaps w/o any increase in obtainable accuracy ?
