So I’m just getting back into handling after 30+ years. I got this 6x47 that requires making the brass the correct size and fire forming. I used to do this years ago with a 357 Herrit but like I said, 30 some years ago.
I’m looking for information and advice on the steps involved and equipment needed. I remember cutting the 30-30 cases with a plumbing tubing cutter.
I assume I’ll start with 50 cases and see how that goes?
Again, any advice on starting or problems to watch for would be greatly appreciated.
Thanks in advance.

6x47 is formed from .222 Magnum brass. I had a 6x47 on a Remington 40X action about thirty years ago. I've worked with many wildcats and improved cartridges, but the 6x47 is an easy one. You only need run the .222 Remington Magnum brass through the 6x47 sizing die. You may have to trim the length (I can't recall for sure) and you may have to turn the necks depending on your chamber's dimensions. Many old load manuals have 6x47 data. Be careful of any data you get on the Internet.

That’s some of what I’m trying to figure out if I have to use a mandrel or anything like that or simply use the die and a case trimmer? I seem to remember I had to cut about 1/4” off the 30-30 cases after I had them sized for the TC.

I had a pencil-barreled, 6x47 Kimber in the late '80's. I don't recall trimming, other than for uniformity. You neck it up, load the 6mm bullet, and, upon fireforming, the case actually shortens a hair.

I don't have any of my reloading records, only a couple of targets showing 5-shot groups of .375 and 1.1" at 100 and 200 yds respectively. My load was a Sierra 60HP over H335.

You'd have to work up your own loads of course, but I would have tried a half-dozen powders and shot a lot of 200yd groups to arrive at H335 being best in my rifle.

As stated the 6x47 is pretty easy. It sure ain't a 30 Herrett. You will have to trim the cases somewhat and chamfer the inside neck. 222 mag cases can be a bit hard to find. I happened on a whole bunch of them years ago at an auction. So many I had to find a 222 mag rifle. The 6mm version is a good accurate caliber. Have fun with it

My gun is a Kimber 84. I had to get a glass stock made for it and it weighs 5.5 pounds. Guy I bought it from had broken the original wood stock.
I’ve acquired some Norma 222 mag brass already. Dies are in the way so I’m close to being ready to try to load for it.
I’m assuming the process is run the 222 mag cases through the sister die, trim to length and load with about a 50% charge and fire. Then the classes will be done or do they need trimmed again?

Good comments in the previous posts. I think you'll find this a straightforward task. Like you, I went round and round with a .357 Herrett and and 7mm TCU back in the day. Both required annealing and trimming. The 6 x 47 Remington is nowhere as troublesome.

A year or so ago, I picked up a 40 XBR in 6x47 Rem in Cabela's gun library of all places. It looks like it had been sitting in a safe for the last 40 years. It was a great deal considering the goodies that came with it. Nobody wanted it except a guy like me who had been wanting one for a long, long time. I guess I'm a dinosaur . . . .

A few thoughts: Use a good lube when you reform the cases. I use Imperial Sizing Wax. As noted by others, you simply run the .222 Mag case into a sizing die. Be sure it has a tapered expander.

My rifle came with a set of Hornady dies, and IMHO Hornady should just stick to bullets. Now I only use the die set for case forming. I quickly went to Wilson sizing and seating dies. Their website is a little quirky, but they guided me to the right parts by email. Great folks!

Brass can be hard to find, but it's out there. I see Midway has some in stock at the moment.

And lastly 6 x 47 confuses some people. Often they think 6 x 47 Lapua and have no clue about the 6 x 47 Remington.

I called RCBS and they had a few sets left. Now they have one less. That’s very good news about the trimming not too overwhelming.
Have you used the Hornady spray lube any? I hear it’s good stuff but never used it yet.
As stated earlier, I’m just getting back into reloading and years ago I used some lube that was applied to a card sized pad. Had to clean it all off after the shell was completed.

I haven't used the Hornady spray lube. Be careful, though. Case forming usually benefits from a better lube than simple re-sizing.

I too remember the "old days" of case lubing. RCBS made a sticky lube you applied to a pad and then rolled the cases on. It was a real pain to get off the cases and it just had to wear off your hands. As I recall, no soap or solvent would get rid of the sticky feeling. That lube was definitely not part of the good old days.

Just get Imperial sizing wax and be done with it. I used it when forming .300 BO cases without a hitch.

A very accurate little cartridge, mine's a 40-XB-BR. Cases are easily formed as stated previously. Might make a note that FEDERAL made and sold 6x47 MATCH EMPTY UNPRIMED CASES that were Nickel Plated, and show up at gunshows occasionally.
FWIW, the factory target that came with mine was 26.5 gr. 4895 w/ 60 gr. bullet.
I settled on 28.0 Gr. of Varget with 68 gr. custom/70 gr Sierras for gophers and PDs.
Keep us posted on how that little Kimber shoots!
BTW- It took me a day to make my first 100 .30 Herrett cases for IHMSA!!!

Good shooting.

Mine had a 20 in barrel. Load from custom shop was the same with H 4895 and a 60 grain Sierra. Help me out can’t you use 204 brass as 222 rem mag is hard to find.

I’ve also read that 204 brass can be used, but I’m just getting started. There doesn’t seem to be any 6x47 Fed nickel plated brass available right now.

Yes 204 brass can be used as well. Mine is a Kimber 6x47 HB. I have both old factory 6x47 brass & resized 222 Rem Mag brass which I just resized, loaded & it shot just fine. My RCBS and Hornady manuals have reloading data. You can also search the Accurate Shooters forum for good reloading info.
My 6x47 rarely sees the light off day. Will probably list it soon.

204 brass can indeed be used, but it's more of a stretch to 6mm than 222 Mag. Midway has 222 Mag in stock, so I'd just go with that. The Federal 6 x 47 is out of production. You might find some lurking at gunshows but don't waste any time trying to find current production.

My favorite case reforming lubricant is STP oil additive. Also good for general FL resizing.

Dawn dishwashing soap removes the lube from cases and hands. I never buy hand cleaner anymore, just Dawn.

Supposedly several "case lubes" were simply"repackaged" STP!

Yep, cut it 50-50 with 95% rubbing alcohol for spray lubes. Napa brand is even cheaper.

I have a small bottle of C-H lube..If it isn't STP...It should be. Seriously looks like it

My father started a 6x47 project before he left us. I had it finished up. He had a small Sako L461 action barrel in 6x47, I had it stocked in a very attractive stick of wood with checkered color cased steel butt plate and grip cap. Now I just need to get it to the range. I have a box of ammo made from 222 Mag brass. Looks like it should be a fun rifle.
