Twist too Slow For .222 Remington

Q: I recently bought a JGA rifle which had been converted and rechambered from .22 Hornet to .222 Remington. The rifle, including the bore, is in excellent condition. I've tried three different .222 factory loads, and handloads, with various 50gn and 55gn bullets in it and it seldom keeps five shots closer than six inches on a paper target at 100yds. What can I do to make it more accurate?

A: The problem with your rifle is that the .22 Hornet has a slow rifling twist of 1:16" whereas the Triple Deuce has a 1:14" twist which is a tad too slow to stabilize the heavier, longer bullets even at .222 velocities. The only way to get around this is to load 45gn bullets for it. If you can safely work up to 21.5gn of RE-7 you'll get about 3425fps or, if that Alliant powder is not available, try to reach 23.5 of AR2219 for 3340fps. That should make those pesky varmints sit up and take notice.
