was given 500 bx of nosler varmageddons .224 55g FBHP P/N 17290 for use in my .223 (First time using these). i neck or full size with redding nit bushing dies 2th neck tension - on seating these bullets i have found they are sizing the neck while traveling down the neck to the point you can turn the bullet in the case, checked i had the correct bush in the die even seating a few SMK S SBK S + A COUPLE OF FB Hornadys to check the neck tension which was as expected perfect. is this normal for this bullet as they needed a roll crimp to get any sort of usable grip.
