I just wonder how many more wildcats can be made that really fill a niche. Most of the new wildcats I see are just renamed, slightly different versions of someones idea from the past. | ||
|
one of us |
Question is "is it really a niche?" Or just a desire to be different. Second question how much difference is needed to be a new wildcat? When you start talking about a change for 35deg to 40 as the only change I get bored. Problem also as to finding a data base that lists everything that has been done before. As usual just my $.02 Paul K | |||

That's what I wonder about. Let's get this out of the way. I have never felt the need for a wildcat cartridge in my life. I'm just asking a question. | |||

 As it stands today I would have to agree that the NEED for wild cats does not exist. In the past ,however, they did play a role. Just to mention a few : .22 Varminter ( 22-250 ), 22 and 6mm PPC, 35 Wehlen, Huntington and Pages wildcat contributions to the .244 (6mm) and .243,6.5 X .284, .25-06,22 BR. Now if we talk absolute need the 30-06 was not necessary as the 8mm X 57 could do just as well in the field and in the military.  rogerOld age is a high price to pay for maturity!!! Some never pay and some pay and never reap the reward. Wisdom comes with age! Sometimes age comes alone.. | |||

I agree with Paul, are you making it just because you can and want to be different, or because there really is a gap? The other aspect is that it really doesn't matter if it fills a gap if Remington, Winchester, or Ruger don't decide to promote the idea and often even if they do it might never be successful in the marketplace. | |||

The day of the dyed in the wool wildcatter is about over, just no place to go, and that may change with all the new factory cartridges coming out at least it gives the boys something to play with and make great claims of lookie what I done done!! but in reality I doubt that much is to be gained with wildcatting other than intertainment..I used to be a wildcatter back in the good old days, but I got in a little late also.. I still play around on rare ocasions, like my 6x45 and my 375x62 but both have been copied or were already there when I did it...Not many 6x45s when I built mine and the 375x62 is a first as far as I can find out looking for load information that does not exist, but the 375 Hawk and Hawk Scoville are real close, but I still have about 4% more powder capacity than either of them for some reason, and that means nada in trajectory or killing power..It is easier to load however, just run a 9.3x62 case in a 375x62 die and bingo..I only opted for the 375x62 because the 9.3 wouldn't clean the bore on a rebore. I felt in the 50s that the factory had about all we would ever need so mostly gave up wildcatting as it was damn expensive and resale then, as today, was limited. I don't feel like we ever filled a "gap", it took a lot to fill a real gap with a caliber even in wildcatters heyday...Just my approach and opinnion on the subject.

I have a collection of cartridge drawings that is 1600+ strong. Some of them are old cartridges, some are new or still common, and many are wildcats. Every day I read of another wildcat(s) that I’ve never heard of and have no idea what they look like. I find it interesting and just wanted to know what you guys thought. | |||

Mich, I think many wildcats were built to fill a niche as you say. As Ray siad those are getting numbered. I built my first I designed in about 1980. It wasn't about niche but efficiency. If you plot up the smaller 7mm case using capacity and velocity you get a pretty straight line (assuming equal pressure) then take the cases 7mag and larger you get another straight line. I designed my 280PDK try to hit that intersection. Feeling that was the point that efficiency dropped off. That is about 75grs. So minimum taper, .284(1 caliber) neck 40 deg shoulder was born. Would it do anything a 7mag wouldn't. Nope. Just did it with less powder and allowed 5 down. Could I beat factory 7mag yep, handloads not without about 2" of barrel advantage. Most of the other wildcats used the same case designed necked up or down. The other keeper besides the 400 was the 6.5. I could match 264wmag handloads with no barrel difference. Again didn't fill a niche at all but really pi$$ed off my buddy with is 264.  I would wager that a lot of wildcats are just playing around like I was. Most of the niches have been filled. As usual just my $.02 Paul K | |||

550 express and flanged. Never anything even close to them. My 416,458,470 accrels - same capacity (slightly larger actually) than a full length improved hh case In a standard length action. A holy grail if there ever was. 500 accrel. The 500 Jeffery perfected, at Least to my specs. Don't listen to ray on wildcats. In fact He contradicts himself mentioning new factory rounds The 340 accrel. A 375 ruger necked to 338, running at win mag Vels and about 15,000 lower pressure than the Winmag. In a standard length action. 257 accrel. 257 weatherby results at 52k psi not 62. Wow. Holy grail stuff again.

We designed and built a number of wildcats based on the 404 case. We started off with a 375/404, as I wanted to have a bit more velocity than the 375H&H was capable of, and at the same time get rid of the belt. 270/404 270/404 Short 30/404 338/404 375/404 | |||

There are some really small niches out there which wildcats filled quite well. One was for the niche that was/is competitive cast bullet benchrest shooting for score or group. In the early to mid 90's I wanted an easy to make cartridge which would have minimal recoil, use a high quality case full of a medium burning rate powder (but not compressed) and would be capable of delivering 2,200 fps MV with a 215 grain high BC bullet for bucking the wind. So, I put together a ".30BR Long Throat" cartridge which I had not seen or read of in CB benchrest competiton before that. It was made by simply necking up the 7m/m BR, dumping in about 30 grains of either IMR4895 or VV-N135, and using a Don Eagan 200 grain bore-riding bullet. Pretty soon that rifle won a national championship and was/is in common use all over that niche. Then two years later, wanting something just as easy to make and with even less recoil, I necked up and long-throated the 6PPC to make a ".30 PPC Long Throat". Within 4 months of making it, it set a national record for 10-shot groups using the same Don Eagan mould and VV-N133 powder, again from Lapua cartridge cases. For some reason it never became virally popular like the .30-BR did. Not the be-all and end-all, but it was fun and it worked. (Of course every one else did their own versions of both cartridges, all of which work just as well. But four different national Champions did use my original .JGS-ground .30 BR reamer and throater for their winning barrels, loaned to them at no charge.) My country gal's just a moonshiner's daughter, but I love her still. | |||

Jeffe, Your remark "Don't listen the Ray" doesn';t make since to me, even if you were right, then you have already invented those wonder calibers, your calibers are not new anymore so than an Ackley.  C'mon, you have nothing really new nor have you set the world on fire, you just reinvented the wheel.

I think there's a nich for a "stretched" 284 Winchester case. When choosing a cartridge for rebarreling, It would fit any bolt face of the 30-06/8mm family. Yes - A 284W case stretched from 2.17" to say 2.54" would be useful. And it wouldn't even matter if none of the big rifle manufacturers picked it up cause all could be rebarreled to it! ________ Ray | |||

What case are you using for the .284 Long | |||
|
| one of us |
Now wildcat it to a .30 cal and compare it to a 30/06. AND a .375 cal and compare it to a 375 HH. ________ Ray | |||

I used the CIP drawing (with all the case data) of the 284 Win and stretched it. It's just a computer generated concept cartridge. | |||

Comparing one cartridge against another takes a little time. I have already compared for myself (yesterday) the 375 version against the 375 H&H. It's not in the same league. | |||

Anddd we're back to the first post. You just designed the 376 Steyr, ha (rimshot)! Try the veal and don't forget to tip your waiters folks. Just goofing... | |||
|
| One of Us |
Although the Steyr is very similar, it doesn't have a rim face to fit a 30-06/308/284 bolt face. Steyr is .496. the 30-06/284 is .473 | |||
|

I know, I just thought it was funny how we circled back around. That would really be a tough one, without a lathe, as there's no readily available donor I can think of. Unless it's really obscure, I think Winchester dreamed the 284 up out of whole cloth. I can kind of see it as a 30-06 rim grafted on the 45-70 family. I guess you could turn the rim down on a 9.3x64? Man, the 375Ruger is just too good, it's really made this a moot point, ha! | |||

There is very little that is truly new in the reloading world. | |||
|
| one of us |
No - Not mute! The whole idea went whoooosh right over your head as you can't rebarrel a 0.473" bolt face rifle to the 375 Ruger without the expense and lower integraty of changing the bolt face. However you could easily rebarrel any of the milions of 0.473"s rifles to a __-284WL. Guess you never had to put a new engine into a hotrod. Well... when/if you ever do - You put in the biggest one that fits. ________ Ray | |||

A number of years ago an extended .284 case seemed to be a good Idea. Wound up going with the .425 WR case. ergo the 8mm X .425WR X 2.500" IMP. Mistake! The two brands of brass available were soft. It now is a 8mm X .404 X 2.500" IMP. ROGEROld age is a high price to pay for maturity!!! Some never pay and some pay and never reap the reward. Wisdom comes with age! Sometimes age comes alone.. | |||

Mick, That 1.438" Bullet is taking up to much case capacity. Try loading it out to 3.36" to see how much more UCC we can get. ________ Ray | |||

When all the smoke has cleared,it's just hard to beat a .375 H+H. As to wc developments,over the years I have come up with some gems,then look in Parker's book + damned if he had not done that same thing 30 years before. Never mistake motion for action. | |||

Yep Norman. That conceptional 375-284WL is still only 92% at best of a 375HH case capacity. But, it still way ahead of a 375 Whelen. ________ Ray | |||
