[QUOTE="MontanaRifleman, post: 773545, member: 11717"] A 10 twist should be fine. That's what Berger recommends and bullet makers are usually conservative. Putting the numbers in Bergers twist calc. length 1.602: conservative vel, 3100 fps, 0 elevation... the calculated SF is 1.59 [url=http://www.bergerbullets.com/products/target-bullets/]Target Bullets | Berger Bullets[/url] If you have a question, Berger would be the best ones to ask. I'm having a Broughton 5C with 10 twist chambered in 300 RUM as I type this. I plan on shooting the 230's through it along with some other bullets. [/QUOTE]
