Berusis,
I only had single shot 40x's so this was not a problem, the 70gr pills, were the norm for BR shooters giving the best accuracy, either the Sierra or custom ( I made mine in Deitch dies). the different rifles had slightly different oal and as they aged 3000-4000 rounds opened up but only slightly.

After multiple weekends spend running in the barrel and doing load development, I finally got to shoot my first field rifle comp with it yesterday.
Got a first place and am super happy with it.
I found myself holding just off the 10 ring for wind, and hitting just off the 10 ring where I aimed.
Fantastic caliber, fantastic rifle......... very happy

Sounds like your gun is living up to it's heritage. Mine is still in the gathering stage. What is your current load?
I have found 300+ 222 rem mag cases to go with the 200 bought from two other sources, so I have enough brass. Having a little delay in getting a reamer but this will happen. For dies i' m going to send a reamer print to Whidden Gun works and they make a custom fl bushing and seating die and the price is very reasonable. Keep us posted on the how tos.

one of my gunsmiths suggested using RWS 5.6x50M brass to form 6x47 cases. they are german made and he says the quality approaches lapua. they are not cheap if you can find them. anybody tried them? i have accumulated some rem 222 mag cases but there is quite a variation in weight and neck thickness, so i'm sorting and turning. my biggest holdup is getting the reamer.

While what you say is certainly true, 204 brass is almost as difficult to find as 222 RM. Also, when you expand the neck to .243 it makes the brass thin. If you are fitting to a custom, tight necked chamber, it is too thin to use and splits easily. There really isn't any easy solution.
On an earlier post RWS brass was mentioned. I use 5.6x50 RWS brass is a 5.6x50AI and it is very good, although hard to find and expensive. Several years ago I was able to do a trade with a friend in the Netherlands and got several hundred pieces of once fired which I was very glad to get.

I put a wanted add on an online second hand firearms website asking for 222 mag brass.
I now have about 850 cases and turned down about the same amount again as I had plenty.
All the rasa is sako and most of it was 20 year old unfired unprimed brass.
You would be surprised what people have lying around when you ask

Now i am no bench shooter. I can actually shoot almost as good leaning on a post as I can off a bench and sight my rifles on off a post.
I have found 8208 and benchmark to work really well, and settled on a load of 28gns of 8208 under the 70gn TNT. I have played with seating depth but found no significant difference between jump or jam with my rifle. The Jammed loads shot a tad better when I got my shit together, but I don't trust my bench skills...... I freely admit I suck at it which makes load development fun.
My load that is about 15 thou jammed worked well. I managed to put 7 out of 10 rounds into a group of a bit over an inch at 200 yards while resting the rifle on my arm leaning on a pole and sitting down.
I still have small issues with what I call steering where I lean into the rifle as I fire the shot which pushes the shot high left. I managed to mentally manage it years ago, but 15 years off shooting, and I need to re-train my brain! but that's off topic.
Some preliminary results from playing with Benchmark (ADI BM2 here in Australia) also showed fantastic groups around the same load volume.
I had a play with ADI 2207 which is the Aus equivalent of H4198 or Reloader 7.
I just couldn't get it to work well in the longer 25 inch barrel I have. The cartridge seems to prefer slower powders that fill the case the the base of the projectile half way up the neck.
I'm using match prepped sako brass and CCI BR4 primers.
Another note......... I can not speak highly enough of the Krieger barrel. It cleans up so easy its ridiculous. I love it!
Cheers
i can hardly contain myself! i spent almost 3 weeks trying to get a reamer print for my build using reamer maker A, they are now ancient history. asked who else should i consider and JGS was mentioned so many times i had to call. i called on monday, got a reamer print in 2 hours, called tue and requested a few changes(30 degree shoulder and tighter neck), got that print wed am, called wed pm and confirmed and it is being made, hopefully arriving in mid to late april! this is service beyond belief! i will be a repeat customer! i am mailing the reamer print to whidden gunworks and they will make custom fl/bushing die and seater and they were prompt and everybody i spoke with knew their products, unlike my experience with reamer maker A. i will be shooting bullets weighing 55-66 as my twist is 13.5 and my 6x45 shoots these nicely. i appreciate any suggestions re powder and loads...i actually have 2#of the original T32. also LT32, 4198(hodgdon and imr), benchmark, h322, rel 10x, n133, tubal 3000(made in france and shoots fantastic in my 20 tactical with 35 gr bergers). this will be a switch barrel so i got a bald eagle barrel vise. i am ready!
I have been using my 6x47 Rem a bit lately, and on its competition debut we got a first place 8)
It shoots like stink and I have complete confidence that if a shot wanders into the 9 ring, it was me!
I am using 28.6gn's of ADI BM8208 (I'm Australian) under a Speer 70gn TNT jammed 0.010" lit by CCI BM4 primer in fully prepped Sako brass.
It shoots 0.25" no problems with the rifle in a stock that's not the most bench friendly for tiny groups. I am no bench shooter either and I recon in a better stock, better projectiles and more experienced benchrest hands it would crack into the .1's with ease, but for the shooting I built it for, its accurate enough to hit the 10.1 dot every time at all distances.
I have experienced problems with feeding with my modified magazine. I have removed the 223 spacer to give my full 308 mag length in the standard Remington magazine. I modified a 308 magazine spring to hold a 223 follower at the rear of the magazine, but I am having problems with bullets jumping out of the magazine before the projectile hits the ramp designed to lift the front of the bullet up.
I am in the process of making a half thickness spacer and will go back to the 223 length spring to try and give better forward support to the bullet as it slides forward in the magazine.
I want to get the standard magazine working as a detachable mag setup would get in the way of my hand placement during offhand shooting.
Hell... I like it soooo much, I even sold my .222
Edit.... next step is to get the 80gn Berger's I have shooting with some slow burning powder, ADI 2206H which is the equivalent of 4895. I foresee compressed loads

Today I got the spacer made and installed. I used a piece of aluminum for the job.
I cut a piece the same size as the original spacer only its about half the thickness. This gives me more magazine length but I can go back to the 223 size magazine spring for more forward support in the magazine.
I drilled 2 holes in the back of the mag box and drilled and tapped the new spacer. There is plenty of clearance for the 4mm screw heads inside the stock.
My loads fit in with about 2mm clearance so its perfect.
Also, going back to the 223 spring allowed me to go back to using one of the old school Remington cast magazine followers which is curved and shaped to the case, and IMO, just better than the nasty stamped modern one I was using.
I made 3 dummy rounds and cycled them through several times with zero feeding issues. It was definitely more reliable than before when cycled fast and slow.
Will see how it goes next time I shoot it in a comp and the adrenalin is pumping

Got mine (6.5TCU) to feed great finally, with 223 follower and stock 308 Follower spring.
So far so good, stock spring and block in rear of mag would not feed more than a single round in my case
Whats your OAL Brewz? I am loading 140Amax seated to base of neck. I have about 2mm to spare (no spacer in mine)
Was built to be a general purpose shooter to save the barrel on my 6.5SAUM as I like to shoot a lot.
But I wanted to be able to use the same suppressor etc, etc

Hi mate
When it comes to standard Remington magazines, it is fairly well know that they don't like a diet of cartridges with steep shoulder angles.
The 6x47 Rem has a 28 deg shoulder, while your 6.5 TCU has a 40 deg shoulder.
The usual rout to getting these steep shouldered cases like ackley improved etc etc is a good single stack detachable magazine. Your cartridge was designed to be used in a single shot pistol and no feeding issues would have been considered in its design.
Good luck with it.
