I recently acquired a brand new Remington 700 Classic in .223. Already had the 2001 Classic in 7mm-08 which has been very accurate and my favorite deer caliber. Yesterday I mounted a Zeiss Conquest MC 3-9x40mm scope and hit my range for initial sighting in with Hornady 55g soft points. For a new barrel I'm not disappointed in the groups right out of the box. Especially on a windy day. But hoping to get this rifle to sub MOA groups. I've read Remington made the 700's in varmint calibers with 1:12 twist. Can anyone confirm? And if so, do rifles with that slower twist rate compared to most MSR's with 1:8 or 1:9 twist prefer heavier bullets? I have several boxes of Federal Fusion in 62 grain and a couple boxes of Hornady Match bullets with 75 gr BTHP to play with.
Your rifle is twisted all wrong to play with heavies. A 1 in 12 223 rem is only good for about 62gr max. I wouldn't try heavier bullets in it, because you will just be wasting expensive hard to find components. You may want to try to find a different rifle with a 1 in 8 twist barrel, or re-barrel your remington, that way you'll be good for just about any bullet weight you can put in your 223 rem.
