I would guess 26 plus as well..If I had a battery for my chrony I could tell you....

I found out something that everyone told me was not possible.....I tried the 168 gr SMK in my 20 inch 1/10 remington
barrel with very poor accuracy...I use the same loading in my 30 inch 1/10 barre[ and it shoots very accurate....
Explain this...it has got to be the longer barrel is producing more MV and better stableliztion....
