What wildcat cartridge would you create?

[feedr]

One for fun

If you could have any wildcat cartridge cooked up for you, what would you create?

500RUM

..if no shoulder possible then I'd have to go the 500-378...

[yoshie]

9.3x284

[Chronos]

No point, every time I think I've got a good idea I google search and find its already been done.

I'm a fan of the 7mm's so a .222 rem mag case (.204r)necked up to 7mm launching a 120gr balistic tip at around 2500fps (around 200fps faster than a 7tcu in a rifle) would be an easy to shoot mid range cartridge for a light weight rifle. Problem is there's the 6.5x47 and 7BR which would probably out perform it and reamers are already available making it cost prohibitive

Then again the same case (.222 magnum) in .224 with a long, say 28-30" fast twist barrel shooting 90gr bullets could make an effective F open gun, but probably out performed by the 6BR so there's no point reinventing the wheel

i think the new 17 wsm wouldve worked better in 20 cal rather than having it in 17, but besides that everything ive ever thought of has already been done.

As we agreed, most of its been done.

Your 20wsm idea? How about 5mm rem rim mag

The trick is change change one of the case dimensions by a 'thou and give it a jazzy name.... everythings been done before, I think they ran out of case and calibre combinations around the mid 60's...
Now its just marketing; release something new so you can sell it in a new rifle. Solutions t problems no-one new they had until the new chambering came out

Lol. I agree, problem is unless you can convince a rifle company or two to make 50,000 rifles chambered in your cartridge it's doomed to fail. Look at the many chamberings that have all but disappeared because either another similar cartridge was more popular because of the rifles chambered for it.

Things like the .284w, developed for the winchester 88 lever gun. The gun was not a great seller so the cartridge all but died out. Saved only by the 6.5-284 wildcat. It's now more popular than ever because of its position between the 7-08 and the 7 rem mag. Now people are looking at a 30-284 wildcat (strange considering the 7mm's better recoil and ballistic characteristics )

Failure from a marketing perspective of course.... example the 8mmRemMag, failed (if you call it a failure) probably due to the metric name, of course the mericans need an a number like 300, 338 358 458 else they dont capish..... the 8mm chambering though if accepted as a great hunting round in Euro, adding 500fps to the 8x57?? Whats not to like about that, even hotter than the 325WSM

[Lorgar]

For some reason a "7mm AAC Blackout" popped into my head for this.

Except I think the 300 AAC is pretty pointless for me so no idea why I thought of that

[Aster]

You're turning into a 7mm "fanboy"

[RDobber]

Hey, hey!

What's wrong with being a fanboy, huh?!

Go the 300 win mag!

[Aster]

Just the company he'll keep I guess

[Norton]

Oh snap!

Google 7mmTCU, .233 cad expanded to 7mm. A popular metallic silhouette pistol cartridge

Like I said, almost everything you think if has been done

I suppose they've already had a few hundreds years to come with everything.

It's going to be tough to be original

[Lorgar]

The 7mm TCU is basically what I was picturing.

Whether I'd actually 'create' one like the post asks or ever have the need of one? Nah.

Just popped into my head for some reason.

Recoil is soft enough with 120gr loads in my 7mm-08 anyway

[feedr]

Googleing a bunch of info an looking on posters etc.

This is harder to come up with something new than I thought

[bunnybuster]

How about a 7mm/70 based on the 45/70----- why I don't know,7mm good BC,45/70 case- big boiler room,rimmed case for single shot actions,

Be Safe, BB.

I think most 7mm are pointless IMHO but a 6,5-06 now that would be some fun!!!!!!


















Now watch the 7mm guys come out swinging???

The 6.5-06 A-Square uses a .264" diameter bullet loaded into a modified .30-06 Springfield cartridge. The neck is reduced to accept the smaller bullet, the shoulder is longer than that of the parent cartridge, and it has a 17.5 degree angle leading to the mouth of the case where the bullet is seated

lol, i'm yet to read something that is original here. it's pretty hard but easy when you use common cases like the 30-06

6.8 SPC necked down to 264 cal. Would be great in a true compact rifle for shooting the 123g SST or 123g Amax for medium game including pigs and fallow.

this is an interesting one,

for those that don't know the 6.8SPC uses the .30 rem case, shooting 110-120gr bullets at moderate velocities, around 2500fps, and keeps CAOL around the same length as a .223 for the purpose of being used in the AR15 platform
from Wiki:

"In tests, it was determined that a 6.5 mm barrel had the best accuracy, but a 7 mm barrel had the best terminal performance. Further tests showed that a 6.8 mm barrel was the best compromise between the two, providing accuracy, reliability and terminal performance up to 500 meters. The combination of the cartridge case, powder load, and projectile easily outperformed the 7.62x39mm Soviet cartridge, with the new cartridge proving to be about 61 m/s (200 ft/s) faster.[9] The resulting cartridge was named the 6.8 Remington Special Purpose Cartridge due to the size of its barrels and the fact that it was based on the .30 Remington case. However, in the ten years of it's existence, it appears to be more of a General Purpose Cartridge in hunting, military/police & self/home defense."

there are similarly performing 6.5's around, the 22BR case has long been necked up to 6mm, 6.5, 7mm and .30cal, a 6BR will launch a 105gr bullet over 3000fps and a .30BR launches 115's at close to 3000fps, i've thought about a fast twist 7BR for a while as a metallic silhouette cartridge shooting heavier 150gr bullets. might make a good mid range hunting cartridge too as would a 25 cal, 6.5mm or .270mm.

one thing we don't have to worry about in australia is feeding these cartridges through a semi auto platform like a the AR15, but feeding out of a magazine is a consideration so this would have to be taken into account

then there's the 6.5MPC, a .223 case shortened and necked up to 6.5. another one to consider is the 6.5 grendel, a .220 russian case (7.62X39 russian) necked up to 6.5 and built to provide more hitting powder out of a semi auto than a 5.56 (.223) at close range in military/law enforcement CQB (close quarters battle) situations where they don't really want stray bullets busting through walls (or the enemy) and injuring bystanders

Chronos

[bobnob]

Yes Chronos, a good roundup there. The 6.5 Grendel would do all my wildcat offers and a little more. I still like the idea of my 6.5SPC however, or maybe even a "257SPC".

Just warming the arms up now.

.30/.303

Just to get away from expensive .303 projectiles.

I am already using .30 cal projectiles in one of my .303's with great success(just use a .30 cal expanding ball in the die) and the next step is to fit a .30 cal barrel chambered in .303.

It is on the list.

Not getting this, not familiar with and expanding ball in the die?

You seat the .30 cal ball and it expands to .303 in the barrel when shot? Is that right?

[Warrigul]

To get sufficient neck tension so the projectile doesn't fall out of a loaded round you need a smaller expanding ball in the full length sizing die (the bit that opens out the neck after it is squashed down during the upstroke). (I use a factory crimp on the rounds after I am finished anyway for extra start pressure).
