7mm TCU subsonic?

Recommended Posts

Anybody ever try and run 7mm subsonic? Was thinking about a 300 Blackout but I'm not stocked on any ammo or components and after seeing 20 rnds for $30 at the LGS I think that boat has sailed for now.

I've got an old Contender in 7mm TCU that I haven't shot in eons. Wondered if anyone had tried running something like that suppressed? I do have some makins' to get that going.

Thanks, I used to shoot 120gr and 145gr. I'll see if I can look up the twist and how heavy 7mm bullets come these days.

I found that Sierra makes a 197 gr bullet.

I can’t imagine that would be too far off from the 300 BLK subsonic load with a 208 AMAX. Bet it performs much the same.

Ill admit I’d never heard of the TCU family of cartridges, I find them interesting...

In standard loadings it's really a great cartridge. Accurate, flat shooting and packs a good punch. I use reformed 223 brass so it's about as cheap to load as anything.

      I might have made a huge mistake, boys. Could lead to a divorce. I stopped in my LGS (Crossroads Guns, in Fountain City), for some HV .22LR for my Stoeger Luger. I walked out with the .22 rounds and after putting a Walther PPK/s in lay-a-way.  It’s a beaut, a Interarms Stainless steel pistol,  with both mags, box, manuals cleaning rod... all for 5 bills plus tax and BCG. Lay-a-way for 12 months!
      Oh Lord, what have I done???  😆😆😆
      Looks like this!

      Ordered a Shadow Systems MR920 optics-ready Combat model tonight.  I should have it within the next 21 days according to the terms of the sale.  Everyone is so damned backlogged due to the volume of sales lately. 🤪

       
      This will bring me almost full circle back to a Glock 19 sized gun.  I've got a few G45 models still that I won't part with, so that covers my 17rd Glock platform needs, but I have rediscovered the desire for the G19 size during some recent training.  Oh well... it's not like you can take money with you when you go, and my kids would just spend it on something other than guns.  🙂
       
       
      Now I need to decide what I am thinning out of the herd.  I've got an idea in mind but I need to take some current photos so I can go ahead and list it on TGO tomorrow.

      Went to an estate sale yesterday and picked up this Stoeger Luger .22, with an aluminum frame. I think it’s one of the best examples of one that I’ve seen.  Really a bit surprised by the size and heft. It’s very close to the only Luger P08 that I’ve ever fired! Hopefully I’ll get to shot it tomorrow.
