Ok all. I am trying to decide which 6mm wildcat I want to build on my mauser action. I have read all I have available but still can't decide which way to go. I am really interested in the 6mm-284 and see it is close to the 240 Wby in the performance. I have also heard of a 6mm-06 but can't seem to find much info on it. So I am asking you guru's out there to point me in the right direction. 6mm-284..6mm-06 or what else is out there? I have read alot on this forum on the 6.5-06 but I have a 270 which will do anything a 6.5 will do only better.
For speed, I like my .240 Incinerator (6mm on a .264 Mag case....built around the same time Ross Seyfried did the 6mm Mach IV). I have an article on the round at my website.
I have a 270 which will do anything a 6.5 will do only better.
Funny thing is I haven't noticed one 270 in the 600 or 1000 yd competitions.....I better hurry up and build one so I can get the jump on the competition.

Lofter I guess I was not clear enough for you. I am purely a hunting type..I punch paper only for load development. Everything I own is geared up for hunting use. I do own a very accurate 300WinMag which is a 1000yd contender but once again that is not my thing. To each their own. So I have no use for a 6.5, not to say that it may be a great cartridge for game. I am very happy with my 270 and it's performance on game...as well as a few hundred thousand other 270 toters. So to clarify for the confrontationalist, I am asking about the best 6mm wildcat for hunting purpose..and maybe some load data as well as proven game performance.
The 6/284 is a great cartridge, Had one for years and really liked it. The 90 grain HPBT was a very good preformer. Your will like it and it is easy to load. Good Luck
how bout a 6mm ackley 40'....should be right there with most of the hot 6's.....ez...to fire form.....and should be tons of data out there somewhere. shouldn't be as tuff to get to feed as a 6-284. I have (2) 6.5-284's in sporting platforms btw. Look at the bc's on a 6.5 nosler BT. versus the 130 for the 277. I also own 2 fine 270's....and they are no better than my 6.5's.....killing power accuracy or whatever.

A lot of people used to do 6mm's on 6.5 Rem Mag brass....the problem is that case capacity isn't much different than a 6-284 or .240 Weatherby (6.5 Rem Mag is also sometimes hard to find).
You might want to look at the 6 mm Remington. Its not a wildcat but you can do some pretty neat stuff with it. Because of its inherent accuracy, it would be my choice if I were going to build a rifle to shoot NRA highpower.

I have looked long and hard at the 6mm but wanted something a bit different. I own a 243 now but feel it lacks long range punch on antelope and the likes. I would love to see some more information on the 6mm Ackley, I had a 257 Ackley a few years back but it was built on the wrong lightweight platform. Inaccurate piece of junk..but a fun round. lofter is feeding a problem with the 6-284? do you have much trouble with your 6.5-284's? This is the kind of information I wanted. Oh and by the way...I yeild on the 6.5's..good B.C.'s better S.D.'s..just never really paid much attention to them in the factory offerings. Wildcats show alot of promise. Have you done much varmit hunting back in PA. with them?
Kag358--ok here goes--I am a big time dedicate of the 6/06. A couple of quick thoughts.
#1--it feeds and it feeds flawlessly--with the 6/284 I have not been able to say that. They will feed, but not like the 6/06.
#2--you will have more round capacity in the 6/06 compared to the 6/284. One to two rounds for the most part. Generally two from what I have seen. When hunting predators this is awefully nice.
#3-quick and easy to find and make brass (25/06 necked down.
#4-when comparing apples to apples when it comes to tube length and speed. I've yet to of found a 240 Wby or a 6/284 that will run with a 6/06. Some are close but for the most part the 6/06 beats them to the tape.
Here are some quick speeds that have been attainable in the 7 tubes that I have worked with. All are Nozler Bt bullets and all in Rem Nickle cases with Br2's.
This is using a 10 twist or twelves-I prefer the 10's. And they are cut at 25".
Questions--just ask...

One last thing as to this 6.5/06 vs the 270. First off I haven't heard of any 100 yard guns put together in a 6.5/06-6.5/284 yes but not the other. Secondly the 1000 yard game is one that is played by darn few. Thirdly, I'd be glad to play it with my 270's if I had the chance. Would I be the winner-nope don't think so-but I would compete and the winners would beat me because of their ability and not because of BC's.
And lastly the 6.5/06 is a neat round-fun if you want something different. However I've hunted with them both and... in the realy world they are the same. Oh yeah you could micro manage differences to each.
Usually to me when people start to micro manage guns rounds like that they are just letting their predudices show.
Just my thoughts have a awesome weekend.
If you need help with asmith with a 6/06 reamer let me know-Dan Dowling of Colorado does my work. And it has always been superb!

I built my 6mm/284 in 1964 on an FN Browning Mauser action, Douglas premium medium-heavy 26" 1/10" twist barrel. It is the most consistently accurate rifle I have ever owned, despite having a Myrtlewood stock. The chamber is throated for the Speer 105-grain spitzer seated to the base of the neck.
This is one rifle I'd never part with. It is every bit the ballistic equal of the .240 Weatherby, and has the advantages of having NO BELT and a short, fat case which promotes ballistic consistency. The 6mm/'06 or a 6.5 Remington magnum necked to 6mm would provide essentially the same performance. The only drawback I can see to the 6mm/284 is the fact that this case is harder to get to feed well from some magazines. Mine feeds great, but I just can't recall if any modifications were made to the action by the 'smith who installed the barrel and did the chambering (Shebal's Gun Shop, Fairbanks AK). I use mine mainly for hunting deer, and have shot a woodchuck or two with it; however, it has had less than 500 rounds through it, so the barrel is still pristine!! I like the 6mm/284!!
Mark D thanks alot for the info. I live in Colorado so the information on your smith would be welcome. I would prefer to stay with a 6mm, I feel there is a better selection of bullets to choose from. The idea of easy forming and brass availability really appeals to me. As for the feeding issue I can't say because I do not know.. I do know I have never had feeding problems with any chambering based on the /06 case. And for me the less headaches the better. By the description of your obtainable velocities this is the range I would like to be in. I know I can find dies for this chambering easily at midway.com. Is there any need for neck thinning when you size down a 25/06 to 6mm ?

Select a bullet first. If it's a 100 gr SBT then the big cartridges will push it out at 3250 or maybe 3300 fps. A 243 Win with the same length barrel would do 3150. That's not much difference at all. Now a big capacity cartridge is worth doing to get the most out of the gun but it's never going to be a 7mm Mag at long range on game in my opinion. Another thing is that once you start necking up or down it just complicates selecting good cases for neck wall thickness and tension. When it comes to that and runout I like factory cartridges.
Your question is a valid one and the answer is that there is not really a good, big 6mm case. The jury is out on the 243 WSSM also.
Sierra #5 has data on the 6mm/284 and the 6mm Improved.
I went with the 6mm Remington for varmints and I start at the 270 for game. Bigger is better.
Kag, I have a 240 Gibbs built on a Win 70 action, gain twist fluted stainless Ron smith barrel, HS Precision stock. A great setup. Cases are easy to form from 30-06 or 25-06, it's faster then a 240 Wby by at least 100 fps with any bullet weight (I'm concentrating on 107 MKs right now). Just my two cents worth. - Dan

If i was gonna put together another 6mm for coyotes, it would be strictly a spot and stalk long-range rig, and i think i'd go with either the 240 Weatherby, or maybe even the 6mm-.350 Rem Mag. They'd both be a 9 or 10 twist, and although you wouldn't get a lot of barrel life out of either one, with a VLD Sierra, Hornady, JLK, or Berger, man could you reach out and touch 'em.

I have a 6mm-284, built from heavy-barrel 700 in 243. It is a short action and I had it short-throated so the rounds would fit in the magazine when seated out to the lands. It feeds decently from the magazine. Nice accurate gun. I got 220 rounds of unprimed brass and necked them first with a collet on a South Bend lathe before sizing them in the reloading die.
If I were doing it again, I'd think long and hard about 243 AI.

The only worthwhile 6mm wildcat I know of is the 6x45 (6mm/223), and thats debatable....The rest are surrounded by calibers that will do anything the wildcats will do and they come in factory configuration....
The glory days of the Wildcatter are over boys, all thats left is fun and games and a repeat performance, nothing left to show, prove or invent......

Ray in what part of the original post did you see the part where someone was asking if wildcatting was a good idea or not? I did not see it so am sort of puzzled by your response--well not really I am beginning to know how you think.....

I built a 6X45 on a Sako Vixen for my Dad. Very light Shilen 20" barrel with Exhibition walnut. Sako action was a little short for longer bullets but was a fine deer rifle.
I think you are wrong about wildcats, Ray. May make no sense but we are bound to keep trying for the ultimate chambering

I'd like a Remington 600 in 6x45mm, think it would be a very nice gun. Also wish Savage would make a .243/20gauge, but they aren't interested.

Maybe, but slower powders and fatter cases have provided us with newish entertainment for 20 years after the last time it looked like that. Who knows what's next?
