Since this has turned into somewhat of a show off your rifle thread....
I started out calling with this; A CZ527 Varmint Kevlar in .223. I rapidly decided I needed a shorter tube than the 26" OEM...so I had it cut to 18, and threaded. While I was there, my smith talked me into chambering it in .223 Ackley. A DIP extended rail, with a Leupold Mark AR 3-9 , and a dipped HS Precision stock round it out.
I inherited the gun from my father, who sort of neglected his guns toward the end. The barrel in this one is a sewer pipe...there is a inch long portion of tube where the rifling is completely gone on one side. The rifle is a 12 twist gun, and shoots 50gr VMax at 3510fps a bit under an inch, and thats as good as she will do. Thats been plenty good enough for a LOT of dead critters....but time and experience made me want more...more speed, more bullet, more range
That rifle led to this....a trued 700 action wearing a 22" CM 8 twist Shilen tube in .22 Creedmoor. Stocky's Poly stock, Magpul DBM, Sightron Stac 3-16 in PRW rings on a set of XTR bases. This gun is currently shooting 69gr TMKs at 3550fps with boring sub half MOA accuracy. This will be the guns first full season....but everything indicates this wil be a winner....until the next thing
Everything is a progression....but starting out with decent gear allows one to focus on what you like and dont like, what you want to change, and what you want the same. Even with that sewer pipe barreled CZ, I know exactly what it will do, and what it wont...Accuracy is awesome, but consistency is even more awesomer.
