Have been shooting a PSL from a kit purchased when the first batches were imported years ago. Running Czech light ball I couldn't get much of a group out of it. Tried a few rounds of Winchester 180 gr. FMJ and was able to start seeing some 1 1/2" groups at 100. Will have to verify those and then start load work up. Anyone else have suggestions for loads that are accurate? I'm running a Russian PSO scope, 4X.
