Thanks for the bullet tip SamO. I don't reload now but can see it in my near future. Also to clarify another post - i have not even tried 180s. Only 150s and 165s.
On the 11 twist concern, the gunsmith rebarrelling a 300 rsaum for me right now doesn't think 10, 11, 12 or 13 twist is a problem for 150 to 180s. He is a 1000yd benchrest guy and very highly regarded on this forum and others so I trust his advice. In fact he recommended a 12 twist for my 300 rsaum when he could have recommended anything since he was ordering the barrel from hart.
