Range Report Will .243 105g stabilize in 1/10" twist in Kansas?

[DarinR]

Has anyone experimented with the 105 AMAX or similiar bullet in a 1/10" twist .243 Win barrel at an elevation similar to Wichita, KS? Wichita, KS is right around 1300 feet above sea level.

I am trading for an AI AW .243 barrel with a "regular" twist so I assume it is 1/10".

What is the heaviest, highest BC bullets I can stabilize at this elevation?

Thanks,
Darin

I'm at 361ft with a 9 1/8 twist and cannot shoot 105 scenars. I would think you need at least 9:1 for the Amax. I shoot the 90 scenar .420 BC.(if I remember right) and it works well for me past 600. I started a post over this not to long ago, got some great answers, check it out.

Thanks H5N1. I will search for that information.

I think you are going to have a hard time stabilizing it with the 1:10 twist. My Remy with a 1:9 1/8 is just barely doing that.

My .243 10 twist stabilizes the 105 Berger VLD....but I live @5100' ASL.

They stabilized in my 6mm Ackley at tame velocities here in MO and it has a 1-10" twist.

Thanks Guys! I will try some without much expectations. Maybe it will work. Maybe at Cheyenne Wells, CO this coming weekend.

Thanks,
