'Dedicated' to the GTC since I have 3 CZs and a couple of 10-22s, and don't really need another 22LR shooter...... that, and the T/C makes it a bunch easier to hit a center fire primer!! smile

1st up was some CCI-SV TARGET just to get sighted in, all shots were at the 25yd bench, 10 shots..

Next was just a 10 shot group with no scope adjustments..

Went on to try SK Standard Plus, again 10 shots

Finally got to the 22 Center-Fire stuff, shot all that would fit in the chamber, a few were too snug to push in, most were too fast, will dis-assemble and regroup.. 15 shots +/-

The 22-GTC, basically a dimensional copy of the 22LR with a Center Fire primer...

The never fired T/C Bbl will likely improve a bit as it is shot and cleaned..

Then went on to the 10-22, had acquired a fast twist Bbl, Bentz chamber, and wanted to see how it did with the Aguila Super Sniper Sub-Sonic stuff, 60grain bullets.

1st, shot the CCI-SV Target, 10 shots. Maybe not quite as good as the T/C.

Then the Aguila 60 grainers. Again 10 shots.

All in all, a good day..

Pretty cool stuff. Did you try anything at 50 yards?

I have not gone to 50yds yet, I think DD has.... and this is really his brainchild! Looniness can and does run deep, occasionally.

But if it were'nt for 'some looney' think of things we would be missing. I mean if some body had not woke up one morning and said '...I think I'll make a barrel .007" smaller than the good old, long lived, main stream, workhorse...' we wouldn't have the 270!

I had tinkered with this off and on a bit, actually modified a 10-22 so that the CF 22 would function..... it did, but the 10-22 chamber was a little large for continued use of the brass...... the normal one shot and in the trash works well with larger chambers.

This day I was just shooting up some stuff I had left over, different powders and such. Not going to, or even try to, reinvent anything, DD has already done that, and set the bar pretty high. He's posted some targets showing accuracy that a lot of the RF ammo makers fail to meet.

But I'll get to the 50 line eventually...

Maybe one day CZ, or others, will offer the 'Looney Option' with their bolt action line of 22RFs, a Center Fire bolt for the reloaders!

For now the T/C Contender works very well.

Anyone have a CF bolt for 452,455,457??????
