the 243 is the culprit, although the swift was never very popular. grew up in sw va where groundhogs were the primary use. first cf 22 was a 219 wasp. you'd see more wasps than anything else. knew one guy whose father had a m-70 in hornet, cut down so it would fit in his truck. just messing with the collectors. but i got a pre war swift in a model 70 for a good price in the 60s. the 22-250 put the last nails in the coffin. all of mine were accurate, used 4064 mostly. got two 77s when they came out, one hb and one sporter. both shoot good.
when brass was not available, i found 6 boxes of win in the yellow boxes. shot more accurately than any of my handloads, best in the m-70.
as for twist, i'm waiting for a 1 in 4 twist shooting 125 gr 22s! maybe in a couple of years.
