    1 in 10 should work for the most of but most people are using like 1 in 9 for the 300gr bullets. Myself I have a 1 in 10 shilen on mine and im using 300 gr bullets.

    So with a 9.3 twist can you still shoot the 210,240.250, to with no problems.Or only with the slower twist 1-10.

    Thanks alot for the help guys

    My rifle has a 1 in 10 twist and it shoots all bullet weights well.
