Loon Master Dan,
This idea of yours and the whole thread are worthy of an Icelandic saga.

We will see what we see on the journey, no?
Up close inspection of dims gives rise to a problem. Case walls are a bit thick and diameter a bit small. Oops. Will get back on the hunt when this is sorted out. Dang it all. Talking only a few thou for each but...
Loon needs a different tune?

Loon needs a different tune? Inside or outside? I'm hazarding a guess at...................outside? Squib load to fit it to your chamber? C.O.W. ? The pellet and primer combo someone mentioned above? I have faith in my fellow denizen of the baser, deplorable thread, that loonyism will triumph...................... for the good of the world. Geno

Oh, we will prevail, let there be no doubt. Neck OD is ~.220-.221, case wall ~.0095-.010. Spec was .224/.007 and the bullet heel is .210. Curious side of this is the mundane nature of the .22 RF belies the narrow scope of dimensional tolerances. Yep, there is some wiggle room, but not to the degree found in more conventional CF brass.

Well, time passes and courses change. RMC can KMA. Day has been saved by Jimy here on the 'Fire and there is a new dawn on the horizon. ![[Linked Image]](https://i.imgur.com/Zfd0Yg1.jpg) This discussion involved a bunch of loonies, but one of my favorite versions was Crossfireoops. I had promised him a supply of the bullets above before he passed and we had a lot of phone time discussing the ins and outs of this endeavor. Whether it flies or not is unknown at present, but in the event it does it will be known as the .22 GTC Semper Swamp, Dan PS: More as this develops. Anyone got any load data for .22 RF rounds?

...it will be known as the .22 GTC... That caused my allergies to act up... Thanks for doing that, Dan. Back to the subject at hand, as Greg would have wanted, what did you wind up doing to solve the problem(s)? When you said that O.D. was too small and brass too thick, first thing I thought of was a swage, much like a Lyman "M" die, to expand the case and still provide sufficient neck tension while filling the chamber. From the pic, it looks as if you neck reamed them? That then begs the questions; Would a Lee-type collet crimp die work and, will they need to be re-sized? Is RMC out as an option if another looney looks to duplicate this round? Ed

Ed, the RMC brass was sufficiently out of spec so as to be unusable. Sent it back and was advised they were shutting down as of 10 Jan, so they have the brass and my cash. Left me with a bad attitude toward the company.
Stuff that just arrived was spot on spec wise and the results are in the picture. There be a few more steps ahead before determining this is a viable endeavor, but on assumption the preliminary tests are successful I will order up some more cases and get to work. Mentioned previously this is an exercise of dimensional details. They aren't all perfectly settled yet but are close enough to advance the project.

I believe that I shall bookmark this and am eagerly awaiting more results.
These are my opinions, feel free to disagree.

Crow, I looked at that earlier, thought it over and raised the bar. When all is said and done if I can't shoot some ragged hole groups with this set up I'll be disappointed.

Never doubted the outcome of your project. Just wanted to see a smoking crater..... Only reason I threw it out was their mention of powder. I never thought of 700X as a potential candidate for reduced loads. After allowing the acetone to evaporate overnight add the propellant; the kit includes load data for several powders, including 700X and Unique as well as for Hogdon’s Pyrodex P black powder substitute. Now crimp a bullet in place and you’re ready to shoot. .

My imagination tells me that WW231, 700X, Bullseye will get a trial. If all else fails I have a supply of 3 fg and 4 fg. Oddly enough I fiddled with some 3fg in the Sneezer awhile back. Numbers were quite good, particularly the ES. Full case of powder mildly compressed ran 950'ish fps. Cleaning the suppressor was a snap in the dishwasher.

I'm thinking your going to need a depriming tool, here some time, we can make one from a 3/16 drill blank., grind it to fit .08 hole. might have to go with 5/32 OD to go thru the sizing die, hell an 1/8 would work as short as it will need be, give it some thought. A simple 7/8-14 bolt cut off with a drilled and reamed hole would work as a holder with a set screw for adjustment.
I got the plague Friday, due to an overactive snot gland, I have snot coming outta my eyes this morning, a rush job due tomorrow, then we can work on something, ideas ?

Left me with a bad attitude toward the company... Interesting, as of this morning, RMC's website shows that the company is for sale, but they are still taking orders... I take it one of our members here stepped up and made the brass for you? Is there anything else we members can do to assist in this endeavor? Other than raise a glass in a toast to you and your perseverance?  Ed

Yes,another member here from the Fire has pitched in. Brass from RMC was spec'd at .224" OD for the case with a .007" wall thickness. The provided .220//010" which is not compatible with a .210" heel on the bullet, that being fairly close to the norm and perfectly consistent with ammo from Europe which was my metric for the endeavor. US manufactured brass has a wall thickness of .008". The RMC rep I spoke with was named Cody and he told me when the order was returned back in December they were shutting down on 10 Jan.
