Shoots1000: All of my 204 Ruger Varmint & predator Rifles have barrels 26" in length - and if I could I would add a couple of inches to them!
Especially afield, I find the added weight adds stability to the sight picture and reduces their modest recoil allowing for me to often spot my own hits (and misses).Where I Hunt LONG shots (400 yards-ish) are the norm.
I vote to leave that barrel of yours at 24".
Best of luck to you what ever you decide on.
