I really want an accurate 243. don't care if it's single shot. the twist rate on the H&R ultra is 1-10" and that is good for bullets under 100gr. //does anybody know if this 243 ultra bull brrl is an accurate shooter with 100gr bullets. I own a 223 which shoots 55gr so I want an accurate 100gr 243 next. did not buy yet, just lookin at this 243 ultra and drooling. HELP
