The PLINKER idea is interesting! I've been working on one although using a different cartridge case. About what charge of Unique did you try in the 22RE? I figured a plinker would be a perfect candidate for cast bullets.

I've been running cast boolits from 1750 to 2450 fps already. The Plinker? About 1.8 gr of Unique pop pop pop pop pop...... ;D

About 1.8 gr of Unique pop pop pop pop pop...... ;D Tim, That velocity range is perfect -- what powder, powder charge and bullet weight or weights did you use. Also, do you have any idea as to the velocity when using 1.8gr of Unique and what was the bullet weight? I wanted a plinker with a velocity actually in the 1800fps range but up to 2450 would be really nice. I've been playing with .223 cases with 6.0gr of Unique and 55gr bullets but I would rather use a smaller case so I'd need less powder -- an economy version.

The 22 RE w 6.3 gr of H110 and the Armscor 40 gr JFN does 2500 all day long and it is about 90% case capacity. The 1.8 gr of Unique with custom 62gr JHP does 1000 fps. The cast boolits I have are 37gr FNGC and 57gr RNGC. Might look at shortening the Reed Express to the .843" 30 Luger length but will have to look and see how it looks in the Uzi mags, the feed lips have a bend right at the RE shoulder.

I thought you might get a kick out this picture. The cartridge outside of the Uzi mag is a 22X21 and might fit in the Uzi mag with a 40gr bullet. the bullet in there now is a 35gr V-max. the 2 in the magazine are joke rounds -- basically a 25 Luger. I used 25acp (0.251") 50gr bullets. I think I measured the water volume of the 22 Luger and found the volume was small. Turns out I was screwing around and made the 22 using a 9mm winchester magnum case down to the size of the luger for some reason. The volume is probably a bit more since the web is probably thinner. The smaller case should help keep the powder charge down for use in a blowback.

Sweet~ Interesting post I found related to the 224 Boz, a modified 10mm case: These trials most favourably compared the .224 BOZ against the 5.7 FN P90 and the HK MP7. .224 BOZ was shown at the Shot Shows 1999 and 2000 generating tremendous interest, however, the inventor's policy of preventing sales to civilians restricted income and funds dried up. The concept was solely to be made available for anti-terrorist and special forces use. In 2010 work restarted on re-working .224 BOZ into a 9x19mm necked case to .223 and with a partnership with a leading ballistics engineer a new range of projectiles have been created. Despite decreasing the cartridge case volume velocities in excess of 2,200 ft/s (670 m/s) have been achieved. New handgun conversions are being developed that allow simple drop-in conversion of any in-service 9mm platform which gives a substantial increase in performance enabling a user to retain weapons already in use. This conversion is a simple recoil spring and barrel swap. Initially, this is being restricted to service handguns with SMG conversions planned for early 2012. Projectile options now give the user a wide selection of terminal effects and anti-armour properties. The .224 BOZ is developed by Civil Defence Supply, Lincoln, United Kingdom. From original work on lightweight 5.56mm projectiles a new study to improve the NATO SS109 5.56mm began under the title of the SWIFT Project which is on-going, as of 2011. Similar work is taking place, as of 2011, in the US with the improved 5.56mm M855 A1 and SOST M318 Mod0 and M319 Mod 0 recently adopted by the US Marine Corps being cartridges developed specifically in response to combat lessons learnt in Iraq and Afghanistan. Looks like they are trying to out spend us on the Uzi mag concept! Fired the 22 RE and 9mm yesterday with the modified Uzi mag adapter. 100% feed from both rounds. The sub sonic 22 RE is crazy quiet. I didn't have my camera to take a movie so I'll try that tonight if I get a chance. Converted a bunch more brass last night and will see what the sub loads do in the DI upper with the faster twist, as soon as I can..... Reloads: Testing the "full power" loads in the blow back, this brass is beat to crap. Attrition is high, but some of these cases have over 10 reloads on them. I didn't anneal the cases at all before forming so I might look into that. I also have about 3 cases that don't have tight primer pockets anymore. It is 95% S&B brass and I haven't taken any of my original Starline Tok brass and tried this yet. Like I said way earlier in posts, I size the brass with Tok dies first and if the case mouth isn't perfect, I don't use it because it will be junk if I do. Fun fun fun.... $$$$$$

With the heavy bullets we got the DI upper out and fired off a few of the 1.8gr loads. It wasn't enough to unlock the action so we bumped things up to 3.0 gr of Unique. That loads calcs out to around 1500 fps, but still not enough to cycle the DI upper. The DI definitely needs the slower powders to help it out. I'll think about an adjustable gas block as we move forward. Feeding from a Tok mag seems to give the most versatility on bullet selection however the M1 Carbine mag would be even better. As we found out earlier, the follower doesn't play well with the RE round and really likes to tilt. I'll see if I can make up a different one when I get a chance and go from there. Running the SS109 pulled bullets seated out too far caused chambering issues because of hitting the rifling so we'll have to look at throating the fast twist barrels if we need to. Running the DI vs BB, the DI needs some tuning to be as versatile as the BB, but, 90% of our Reed Express experience has been with the blow back so far. Running the BB with the Uzi mags pretty much locks you into a small number of bullet selections. The DI running the Tok mag opens that up, but it is still limited. I don't know if having to have a couple different adapters around to run different loads would be practical, but, what's practical have to do with anything AR? Stock mags don't work very good because of the short length of the RE so that's not much of an option either. But, hitting 3000 fps with the micro round is pretty fun!

Hey All, Been jammed lately like a lot of us and trying to get some R&R in this weekend... Funny how life works out sometimes and we have spent a lot of time with the Blow Back Reed Express, especially since we stuffed it in the Uzi mags. To put some icing on the cake for us, I got a note from Ron Reed asking us to work with some of his Reed Express customers! Talk about an honor. As we move forward with our relocation, I hope that we will exceed his and the customers expectations with this awesome round!

I will say I now understand you preference for the 22RE. I think I need to reevaluate my thoughts about the 22TCM. I have the 22RE and it works really great. I guess my only problem is that Ron Reed doesn't make large quantities of already formed 22RE brass. Years ago people made 7.62X25 cartridges using .223 brass -- I wonder if I ran some of the 22TCM brass, that's made from .223 brass, through the 22RE FL die and trimmed to the correct length it would work. I've got to use all that 22TCM brass I bought for something.

Yes, I am kinda partial to the Reed Express and am working on the brass issue...

Saw an ad on gunbroker for Glock TCM convsions. They basically take bullets and invert them or cut the tops off and make hollow points until they fit in a 9mm magazine. Then of course they have to have a barrel for the Glock On the Reed Express front, have contacted Starline and S&B about brass runs. Ouch, gets kinda pricey. Going to try some Tok brass conversions and see how they compare with the S&B we have already done, as soon as we get a decent bench set up down here.....

I really like the S&B brass for reforming into the 22RE and I guess you can say there is a plus that comes with it since it's all from loaded 7.62 Tok ammo. You get to shoot the Tok ammo first!
I had some problems with the Starline 7.62 Tok brass getting wrinkles in the shoulder but for some reason the Starline 30 Mauser brass would reform nice. I know I'm not the best brass reformer but the difference between the Starline 7.62 Tok brass and the 30 Mauser brass almost makes me think the brass alloy was different.
Too bad all the milsurp Tok ammo is Berdan primed. Just for the heck of it I reformed some fired cases and they came out as good as the S&B brass. It's a shame that the fired Tok milsurp brass is useless.

I've heard of people "converting" the surplus brass but seems like a lot of work. I've got some Starline Tok brass coming to test reforming and attrition rate.

I've read stories about what people did to make Berdan primed brass work but it's just not worth it unless you have something that requires rare brass and you have no other choice -- but that milsurp brass reformed to 22RE like it was meant for it. Too bad it wasn't usable.
For a while I had problems getting Starline Tok brass so I went to 30 Mauser which worked really great and then when the supply of that ran out I went to 9mm Winchester Magnum brass. I'll be honest, I don't remember if the 9mm WM brass was a pain to work or not. Funny thing is, all that brass -- the 7.62 Tok, the 30 Mauser and the 9mm WM brass -- all costs the same and usually at least one is always available.
