What case would likely form in a 243 Win dye to make a 243 rimmed cartridge with all the same case as the 243 win to make for a rimmed 243 light double rifle? …………………………………………………………... ....Mac >>>===(x)===> MacD37, ...and DUGABOY1 DRSS Charter member "If I die today, I've had a life well spent, for I've been to see the Elephant, and smelled the smoke of Africa!"~ME 1982 Hands of Old Elmer Keith | ||

400/350Rigby and the 400/360 both have a base of .470" The 9.3X74R is close too so that may be the most available brass to get ahold of. | |||

Couldn't you just run 444 marlin brass in a .243 die and trim? | |||

Why not the 307 Winchester? It's pretty much a rimmed .308 Winchester. | |||

I would think The 307 Win is a simi-rimmed case and doen't have enough rim surface to be dependable in the ejector double rifle. The 9.3/74 may well be a good choice. The 7MM rimmed might be a good choice as well! The 444 marlin may well be a choices as well. …………………………..Thanks guys I'll take a look at all the suggestions! ………………………………………………………….. ....Mac >>>===(x)===> MacD37, ...and DUGABOY1 DRSS Charter member "If I die today, I've had a life well spent, for I've been to see the Elephant, and smelled the smoke of Africa!"~ME 1982 Hands of Old Elmer Keith | |||

Sorry,that was not mine,some glitch on the computer. The 375 Win brass can be resized in one stroke to 32 Win Spl.(FWIW) Never mistake motion for action. | |||

I believer the OP question is what rimmed case can used to form a case dimensionally the same as the 243. Base diameter is the most critical measurement So that is why the 9.3x74 is what I mentioned. Are you thinking along the lines of cartridges such as 333 Jeffery rimmed and rimless, 6.5x53R and 6.5x54 or the 7x65R and 7x64? Each pair of these use the same dies for forming but different shell holders for their rim type. | |||

I'm leaning toward the 9.3X74R case as I own two double rifles so chambered and have about 100 empty cases to use for this project. Some question why I do not want a rimless case. I simply do not like rimless cartridges in a double rifle, but I love the 243 Win cartridge for most North American hunting up to and including Mule deer and Prong horn, with varmint hunting as well. I think I will be looking hard at the 9.3X74R . ....Mac >>>===(x)===> MacD37, ...and DUGABOY1 DRSS Charter member "If I die today, I've had a life well spent, for I've been to see the Elephant, and smelled the smoke of Africa!"~ME 1982 Hands of Old Elmer Keith | |||

lets talk about the 375 a bit more. since it can be reformed into 7.62 X51R it could certainly be formed into 243X51R without too much trouble. the OP wants a rimmed 243 type case, the 375 brass clearly fills the criteria and if done properly will have the same case volume as the 243 only with a rim. and if starting from scratch the 303 Brit, 30-40 Krag,348 win and 8X50R case would be on my list too. | |||

I just looked at the 444 Marlin and the measurements are much closer to the 243 Win case than the 475 Winchester. I may try both and see which is best for this project! I will need a set of forming dies custom cut for this wildcat so I'll look at all the suggestions before I order forming dies. Thanks to all here for the help on this wildcat project! …………………………………………….. ....Mac >>>===(x)===> MacD37, ...and DUGABOY1 DRSS Charter member "If I die today, I've had a life well spent, for I've been to see the Elephant, and smelled the smoke of Africa!"~ME 1982 Hands of Old Elmer Keith | |||

You might want to check out those semi-rimmed case rim OD's...the 444 runs about 0.0507-.08" and so does the 356, 307 etc...before you get too wild. I would also check out the 303 Brit and the 30-40 cases...about the same case volume/performance...cases are plentiful AND CHEAP...rim is ~0.540" plus or minus a bit and the base OD is slightly smaller at 0.456-57", so should work MUCH better for a double's extractors...and there are already reamers/dies available for the 303 Epp's version (also the 30-40/6mm/243 I believe) and you DON'T need pricey case forming dies or the chore of reforming...plus A.I. versions. Just a thought. I've used reformed 444 M cases in several leverguns instead of the OEM rimless version, MIXED, rimmed/rimless and never had a hitch...they ALL worked through the action, fired and ejected...but I'm not a doubles man so it might be something to check closely for that application. I should also think that you could use a standard 243 reamer for the chambering if you went that way, then fire form the cases...then you could use standard 243 reamer/dies. You might need to cut the rim pocket separately prior to chambering to get the headspace right, but if you go with the Epps or 30-40 version it's just a chamber job. I've taken the 444 case down to 25 cal just using cheap Lee sizer/seaters and any other 306 case size die I needed to get the step down job done. The 303 Brit and 30-40 rimmed cases were very popular for wildcatting at one time. Good Hunting | |||

NONAGONAGIN: Thanks for the very well described post on this little project! I think your post is very helpful and I will consider your suggestions, they sound very good. Many of the cases you mention I have on hand, as I have owned almost every firearm for just about all of them at one time or another. Thanks again to all who have offered good advice on this little 6mm cartridge. ……………………………………………………….. ....Mac >>>===(x)===> MacD37, ...and DUGABOY1 DRSS Charter member "If I die today, I've had a life well spent, for I've been to see the Elephant, and smelled the smoke of Africa!"~ME 1982 Hands of Old Elmer Keith | |||

As a quick aside...I think the 246 Purdey Flanged and a double rifle go hand in hand...and it just sounds right. You might also take a close look at the 7x57R Mauser case(Rim is ~0.521" or thereabouts) as it is as close to a 246 as you can get...a 246 Purdey Flanged very slightly smaller little brother...and SOOOOOO EASY to do and you could use 243 W dies to form the neck, beside the rimless 6mm x 57 version has already been done, dies are available and probably one of the reamer makers has a reamer available...no need for forming dies. I think you could forgive the 0.004" difference in base diameter given the variations in case dimensions. Besides you could have a Purdey shaped reamer made to x57 specs and still call it a Purdey and have that nice relatively long tapered shoulder for quick loading. If I were a doubles man and a lot fewer projects going on I might be all over this. Hey...LOTS of ways to go here and get your perddy Purdey. Yeah me too...if I didn't already have "TOO MANY STRANGE WILDCATS" hiding in every corner, and too many 6mm Somethings under the table and behind the refrigerator, your project would merit a VERY close look.

there should be a reform die set to make a 7mm round on the 444. it might be helpful in the process of going to 6mm. | |||

This really a pretty easy question (in my opinion). That is pending the performance you are targeting. Just expand the neck on a 225 winchester to .243 A 225 winchester is about the same performance as a 22-250 in a rimmed case. Not sure the availability of brass? EZ | |||

I'm out of here on this thread. I send an email and notify the feller on this post and no response. I think he must be a keyboard wildcatter. I have quite a bit of 250 brass and 225. They are Federal without headstamp. | |||

One of Us |
While the 250 and 225 cases can be wildcatted to 6mm and have already been done in the past, the 225 base OD is ~0.424", rim 0.473" and case volume is ~40 gr H20...MUCH smaller and less volume than the 246 Flanged that Mac was asking about for. Nothing wrong with going that route...ref 6mm-223 and 6mm FB...but again, there are several already-been-done RIMMED cases available that you DON'T have to muck about with costly case forming dies, messing about with case forming or fire-forming or hair pulling....like the x57 case...that are for all intents and purposes ALMOST identical to the 246 Flanged in case dimensions AND case volume...UNLESS YOU WANT a 246 Flanged and can find stamped 246 Flanged cases or have then made. WHY even think about any other cases?????????? If I had a 246 Flanged double made, went to the trouble of having cases made and stamped correctly and some phool started waving a micrometer at a case, he/she might just find reading the spool very difficult with it stuck up some smelly orifice. And...YES...the world is ffffFULL of keyboard wildcatters...you only have to read AR or any other gun related forum for a few days to find many...so whats the big deal? NO ONE really knows what happens to those once the question has been asked and answered unless they post results or pictures. It whizzes me off also, posting my knowledge and information with no thank you, kiss my a** or ph**all...EXCEPT for a few gentlemen out there. This IS a forum where you are supposed to be able to ask questions and get good answers without being pilloried...or shot in the arse. Good Hunting PS: I have a question...[I]EXCEPT FOR DG [/] game where I would want a rimmed case for more positive extraction/ejection...WHY NOT go with a rimless case???? I've seen doubles chambered for rimless calibers and I have built several NEF swap barrel shooter for BOTH RIMMED AND RIMLESS calibers that work properly...ejecting or extracting with little or no problems. Always wondered about this. | |||

Mike Bellm, bellmtcs.com, came up with a program for the T/C line. .444 Marlin cases/shelll holder and the .308 famuly dies. Dupes the .308 with a rim or 7/08 or .358... No reason you could not do this with a .243 but his interest seemed more in hunting rifle calibers than varmint rifle calibers. Costs nothing to ask. Happy Holidays. Happy trials. | |||

I have some other cartridges based on the .444 M case used in Thompson contender hunting handguns. The largest being .411 JDJ, however I do not consider a 243 Win rifle to be a varmint rifle. I have taken a boat load of big mule deer with one shot kills DRT, from 50 yds to 300 yds and never had to shoot one twice!

Does it have to be 243 dimensions? If not, what about the 303/243. Used to be plenty used in Australia although nowhere near like the 303/25. I suppose you being American I should say 243/303 and 25/303. As a side note, the 303/270 was used with 100 grain bullet with the 174 grain Mark VII ammo having the bullet pulled, necked down to 270 and the 100 grain bullet seated over the cordite load. Oh, for the good old days. | |||

Thanks for the link! That may be the best way to go. I don't care if the cartridge is a "WILDCAT" or simply a 243 win "rimmed duplicate" so I can build a rimmed 243, side by side double rifle!

Still wondering WHAT you want..a 243 volume case with a rim or a RIMMED case to neck to 243???...it's been done and all the pieces and parts are available...it's called the 243 Epps/Epps Imp...NICE, wide, fat rim almost ≈0.080"x 0.064 thick or 0.35" per side...MUCH larger than the ≈0.044"/0.022" than the 444 M case...and almost the same case volume in the Imp version...WHATS to think about. You want an easily accomplished 234 sum'n-sum'n for a double...there is is. And there is always all the other LARGE rimmed cases that have ALREADY have been wildcatted and all the components being readily available...38, 40, 44 and 45 cal black powder cases.

NONAGONAGIN, I'm not a wildcatter, and have no desire to become one! As I said at the outset, all I wanted was some information from folks who do these thing just to prove to them selves that it can be done. What I have found is that unknown to me what I want has already been done with the 6mmX62R. That was the answer to my question and if the components are available then that is all I need! …………………………………………………………. ....Mac >>>===(x)===> MacD37, ...and DUGABOY1 DRSS Charter member "If I die today, I've had a life well spent, for I've been to see the Elephant, and smelled the smoke of Africa!"~ME 1982 Hands of Old Elmer Keith | |||

There ya' go...20% more volume makes it a rimmed 6mm-06 basically. PT&G has a reamer...RCBS or CH-4D has the dies...so your set. If you're satisfied that's all that matters...but your getting VERY close to that ....... line....hahahahahah Keep your progress posted, I keep trying to come up with a double I might pop for.
