Thread: Sub 20 inch .223 barrels. Who's running them?

16 inch barrelled Brno Fox, rechambered to .223 - handiest, lightest gun I own.

T3 Tikka 223 1:12" twist.

Measured by closing the bolt and dropping a cleaning rod down the muzzle. Length = 16".

Fitted ASE Jet-Z CQT can.

I measured the velocity at 3250fps when the barrel was 22". After its operation it was 3050fps. So I am happy with that. Ties in with what this web site had to say about shortening a 223 barrel.
Effects of reducing barrel length on velocity

I fired of some rounds when I put the scope on it. Nothing fancy, just got the scope aligned and put 4 shots down range at 100yards one after the other, no resting in between.

I must admit I was surprised at the accuracy of this little rifle.



Dont get too hung up on where I had the calipers etc. I was in a rush. But it pretty darn good. That is 1/3" MOA. Four shot group too not 5, I will do something serious when I get time.



The load was 25 grains of 2208 under a Hornady flat base SP 55gn pill.
