I bought a AR in 22 TCM with a 30 M1 magazine conversion. It doesn't feed well so going to get a magazine conversion from the ARguy that uses PPS-43 magazines.
Anyone use this conversion? A customer at my gunshow setup has the conversion and he says he's functions 100%.

i have a Diamondback DB9RB carbine en route, uses Glock 9mm mags.

my hope is to possibly have a 22TCM9R barrel made for it ... for those out of the loop 22TCM is too long OAL for the Glock mag,

22TCM9R uses a shorter Round bullet, less OAL and fits in Glock 9mm mags

I have an ar in 22tcm. I have had a few "working" modified 223 mags, but haven't been completely satisfied so far. I should have my follower next week and hope it's a winner.

I don't like the idea of having to use an adapter and way less common mags to feed a 223 based cartridge just because it is way shorter.

Can you explain the modified AR 223 magazine to 22 TCM? My 30 M1 carbine magazine conversion has been a nightmare on functioning. Going to order a thearguy.com PPS-43 magazine conversion but can't get a hold of them to place the order. I have a gun show customer that has the PPS-43 conversion and he says it functions 100%.
ASAP
When I get the PPS-43 conversion I'll offer my 30 M1 carbine conversion for sale.

It's basically a spacer in the mag, smaller spring, and a shortened follower. I had a 10 round metal mag working pretty good but it still wasnt 100%.

I'm in process right now on a pmag. If it functions to my liking it will be in an unbutchered pmag, so it could easily convert back to 223 with the original guts.

For a plug and play i would go adapter and pps mags. I've heard they run well. THEARGUY is hard to get ahold of on the phone sometimes. I would just email him.

I'm following this as I would be interested in helping develop a working 22TCM AR15 system. I think it would have very practical applications, for small game hunting, plinking, and economical target shooting for youth.
I like the idea of making the brass from 223/5.56 cases, surplus .22 bullets, and a pound of powder would load a large amount of ammo!

I love my tcm ar. It's my favorite build so far. It's been seriously deadly out to 150 yards on small game.
Now I'm working with a light weight bcg/buffer setup and lower power 33 gr HP loads for a bit quieter close range shots.

My tcm and first load development ladder.

Pretty impressive and i think there's more to be had from it. Just haven't had time to tinker lately.

I did some fitting and adjusting tonight on my new pmag setup. Functioned fine running it by hand and hope to shoot it tomorrow. I still may modify my spacer/ramp design to make it cleaner looking but initial design seems to work...

They look pretty good. Mine is a 1:14 twist it would probably love those. Although it seems to shoot everything I've thrown at it well even up to 45 gr soft points.

My mag setup allows for much longer oal than factory rounds so tips would be no problem.

But at over $1 each I'll pass on these bullets.

Wow didn't even pay attention to how many. That's pricey, will stick to my speer hp's.

Got my new ramps in and shot 5 rounds in a row with no issue. Hope to do some more testing tomorrow but I'm happy so far. I really hope this proves a viable option for 22 tcm and possibly other short oal rounds in a standard ar15 magwell.

I have looked at the tcm powder but never jumped into trying it. Im having great luck with lil gun and imr 4227.

If that is the actual powder armscor is using it might be good to get speed up. Although either factory ammo is very hot and/or primers are soft because i always get flattened primers on factory tcm ammo in my ar.

Arsenal molds got back to me and the nose of their 22 caliber flat sided 35 gr bullet is .135 long. That should be just right for loading the 22 TCM and the 22 TCM 9R rounds. I ordered a 5 cavity mold. I already have the powder coating materials.
Will ASAP on results.

Tried 40gr varmegeddons last night. 5 shots at 50 yards. I think I pulled the last one.

Not sure, i was kinda hurried and my rest wasn't as steady as i would have liked. It might like another couple tenths of a grain to bring it in tighter. Not bad for a starting load.

Going to start at this load and do a ladder. Next time will get a more solid spot for rest and take my time. Most bullets I've tried in tcm are moa or better and this one starting out is or at least very close already.
