1:10 there are gyroscopic stability calculators online that will let you compute this. I handload a 220gr maker projectile at the same fps that barely stabilizes in a 1:16. Maker bullets offers a 250gr projectile on their site that states 1:10 twist only. Winchester should put this in the description.
