Thread: tight closing the bolt

what is the new rifle????
I had a BLR that nearly drove me nuts with same issue you desribing....I would load 40 rounds all the same and 15 would chamber fine,15 tightly and 10 not at all....by taking guts out of an older FLS 30/06 die it seemed to work the bottom of case more and then most would chamber OK... have heard of the small base die thing which shouldve fixed issue. powdered graphite in lid of jar with some birdshot in it,dip necks in before sizing and it will be much MUCH smoother...also take the expanding button out,poke stem in power drill and LIGHTLY sandpaper/steelwool polish the edges..... strangely enough the hornady new dimension dies for the .308 are the only ones Ive ever had issues with...loading for the Zastava had zero issues due to stronger camming of action.
