The rifle that goes to the field with me the most is my .223 CZ527 sporter with the VX-III 4.5-14x40AO on it. It just seems to jump out of the safe into my hand every time I head out for ground hogs, coyotes, or any other varmint. I shoot mostly 40g NBT and it shoots bugholes at 100 yards.
My second favorite rifle is this Savage that started life as a M10 package rifle chambered in .243Win 4 years ago. It didn't shoot worth pooh. I discovered the problem was the barrel after owning it for a year. I bought a used 1:10 twist A&B stainless barrel chambered in 6mmBR for $40.00 thinking it would be a good "practice" barrel while I learned to chamber rifle barrels. I sawed the chamber off, rechambered it in .243Win, trued the action, bedded it, replaced the scope with a 6-24x40AO Bushnell Banner and it turned into a tackdriver with 55g NBT, 75g V-Max, and 95g NBT. I love it when that happens!
I am keeping my eyes open for an irresistable deal on another one of these low end shor action wood stocked rifles to turn into a .338 Federal.
