[QUOTE="ZSteinle, post: 908013, member: 10411"] I would like to see bullet manufactures list the maximum RPM rate for their bullets. This would really help choosing a twist rate for those ultra high velocity chamberings. For instance my 22-243 with a 7 twist will shoot the 90gr. VLD's all day long. load up an 80 grain amax and poof. It will explode before it makes it 100 yards. Thinking of building a 7mm-300 norma mag with a 8.5 twist for the new 195 bergers whenever they do come out but worried with an 8.5 twist will the 168's or 162 amax blow apart? Maybe berger will lead the way and list this information. [/QUOTE]
