Optimal barrel twist rate depends on what type of bullet you are using. Generally, fast twist barrels are used for longer bullets while slower twist barrels are used for shorter bullets. Berger optimal twist rates are based on achieving optimal stability and performance, you can use slower twist rates and achieve good accuracy, although you may not be getting all the BC out of them. Check the Quick Reference Sheets for our recommended minimum twist rates.
