I wouldn't think there would be any problems. I only mentioned velocity/performance in passing. Go ahead and load some 170s up in your 308, check/load for accuracy, keep velocities on the low side and you'll be find...

Important Reloading Data
DeepCurl's unique construction process joins the jacket to the core at the molecular level for excellent performance and consistency. For this reason, conventional reloading data developed for standard jacketed bullets should not be used to load DeepCurl® rifle bullets. Only DeepCurl specific reloading data should be used. It can be found here at reloading data pages in the reloading data pages or by contacting Speer Technical Services at 866-286-7436. DeepCurl handgun bullets can use data from the Speer Reloading Manual #14.
