Does any one have any luck shooting the 55 grain soft point bullet in the 223 caliber AR? I have tried these on several occasions and have found them to be a poor choice. These are not very accurate in the Savage 22-250 that I have and they are not very accurate in my Rock River varminter. I realize the twist of the AR is 1/8. The twist on my Savage is 1/12. Neither shoots the 55 grain soft point very well. Any one else have different results?
