    Will a 111 in 3006 barrel twist rate support a 220 gr bullet?


    Does the twist rate in a Savage 111 in 30-06 support 220 gr bullets? Anyone have good accuracy shooting 220 gr bullets from their 111?

    What bullet range will it support?

    What is the twist rate?

    Thanks.

    At 500' ASL & 59F, a 220gr Matchking through a 1:10 barrel at 2300fps has a stability factor of 1.73.

    1:12 twist barrel has a stability factor of 1.20.

    I do not mean to sound like an idiot, but I do not know what that means. Is a higher number better or worse? What would be considered a good rating number?

    Sorry, I should have mentioned that anything over 1.00 is considered stable, although that is very marginal stability.

    Typically a stability factor 1.4 or higher gives plenty of margin to ensure stability even in very cold, sea level conditions.

    Basically, if your rifle is a 10 twist you're good.

    By the way you twist is 1-10 and yes it should stabilize then but I think you be better of with 168s ;-) or 178s

    Because 2500 fps is kinda slow ;-)
