Re: Small bore varminters
For an off the shelf varminter I would opt for the 243Win over any of the 224 bore offerings simply because the rate of twist on the 243 is more conducive to shooting the heavier varmint bullets, which by the way is what one needs for the longer shots. Most over-the-counter 22 cal varmint rifles sport barrels with either a 1/12" or 1/14" twist and that just isn't fast enough to stabilize the 70 or 80 grain bullets where needed, and the 243s have barrel twist of 1/10" that will handle cup-and-core bullets up to and including 100 grain weight. I believe some of the AR rifles are being built in 223Rem and 5.56 Nato that have 1/9" twist but they aren't my idea of a varmint rifle. Just my 2c on this subject.
