Picked up some 30 cal 220gr sierra MK HPBT (#21662) to possibly use for 300 black out loads. Got to thinking about using it in 308 Winchester 1-10 twist 24" barrel.
My research seems to point to this as being a bad idea. Sounds like not enough case volume or fast enough twist to stabilize this weight. Any one ever tried a 220 HPBT in 308 win? Besides the slower twist rate (1-7 VS 1-10) why would it not work? Hornady book shows a 220 ELDX load for 308 Win.
I have no particular need to use this bullet in a 308, thought just crossed my mind and figured I would ask you good people Thanks in advance for any constructive input.
