Rear lug lock up. They have what I call a 22 bolt on steroids. I have an 06 and 250. I’d keep within specs with reloading, which for the 06 during the years these guns were made was likely 2700 fps, or military spec. The 40/45 was set to a lower price point than the 99 and, though I never heard anyone mention it, because of that it may have helped keep Savage solvent through the lean years of the Great Depression. I think they’re honest rifles worthy of attention.
