[QUOTE="db2989, post: 3084584, member: 129570"] Thank for your input, so this project is also somewhat of an experiment. Cartridge is 308win. The experiment is going to be what variety of bullets can I shoot and their accuracy. Most of my bolt action 308's are 10 twist and my best accuracy comes from 175gr shooting a little over a half inch at 100yds. Now i have tried lighter rounds in them and obviously got fairly poor accuracy. Going off of Bergers calculators and other charts it seems that 12twist barrels seem to provide the proper stability for rounds as low as 147 and up to 175, so the experiment is going to be what groups I can get with a lighter twisted barrel and also if cheaper 147gr rounds can shoot just as accurately if, according to charts, as the heavier bullets in a tighter twisted barrel...
