I have a savage model 10 in 308 win. I have been have some real good groups with 180 gn sst's. I have started to get heavy bolt lift and I had to replace the ejector spring. I am now getting some failure to fire looks to be light strikes on the primer. The load I am using is 44.5 gn of varget. could this load be putting excessive wear on my bolt. I would not think so maybe the parts just need replacing. thanks.
