    i got a 300 win mag with a 1 and 9 twist. Will it shoot the 230 berger? I'm trying to get to 1000 yards. Is this ok or is there something better? 24in barrel? Thanks

    It should be fine. I'm not a fan of the 24" bbl on that magnum. I like 26 as a minimum but the 24 will certainly work. I have a 7mag with a 24" barrel and I did that on purpose to make it a carry rifle.

    Is your rifle factory?

    My 1 in 10 gets the job done with the 230gr OTM's in my 300WM as per Berger/Litz's recommendation.

    Your 1 in 9" twist will be more than adequate.

    Even with a 24" barrel, you will easily be supersonic past 1000 yds.

    You just need to work up a decent load and you'll be all set.

    "Decent load" and "getting to 1000 yards" are subjective. Assuming you're trying to hit a 10" target (about 1 MOA), you'll need to be grouping under an inch at 100yds for starters (half inch would be better).

    A chrony and some ballistics software will help cut down on guess work.

    That's excellent.

    If you know your MV, then dialing in at 1000 yds won't be much trouble at all.

    Just got a chro. graph right now having a brake put on the gun. Then it will be time to dial it in. just making sure the 230grainers are ok before I order some.
