rustybayonet Posted March 10, 2016 Share Posted March 10, 2016 I read on a bolt action, you do not need to size the brass if it will go in the same rifle. Is this true? Link to comment Share on other sites More sharing options...
darkvibe Posted March 10, 2016 Share Posted March 10, 2016 You need to neck size it if it will go into the same rifle. Most people will tell you that you don't have to full length size. Link to comment Share on other sites More sharing options...
shooterready Posted March 10, 2016 Share Posted March 10, 2016 Neck size and bump the shoulder back about .002". Link to comment Share on other sites More sharing options...
Boxerglocker Posted March 10, 2016 Share Posted March 10, 2016 Neck size and bump the shoulder back about .002". In a bolt gun? I've NEVER needed to bump the shoulder back on bolt gun brass fired out of my rifle. I use new Lapua brass and get 5 firings neck size only prior to anneal and full length sizing and trimming.

dauntedfuture Posted March 11, 2016 Share Posted March 11, 2016 No. If you wanted, and your shooting a bolt action rifle, you can deprime and reprime the brass, scoop up some powder and place a bullet in the case. Insert case with zero neck tension in rifle and shoot it without an issue. So technically, no you dont. Also, if you have very little to no neck tension in a custom, tight-neck rifle, then you could also get away without sizeing a case. For 99.999% of other rifles and for all practical purposes, yes you need to at least neck size the cases each time you shoot. For a bolt gun, .001-.002 neck tension is sufficient, for a semi auto .002-.004. I FL size all my brass for all my guns to include NRA LR 1000 yd rifles. Your primer pockets will open up before your necks split or your cases seperate in most cases when your running hot loads. When primers start getting loose i trash the brass.

If I don't bump I have to whack the bolt closed on brass that's been fired a couple of times. Link to comment Share on other sites More sharing options...
rustybayonet Posted March 13, 2016 Author Share Posted March 13, 2016 For my plinkers I will just stay with the FL sizing. Link to comment Share on other sites More sharing options...
427Cobra Posted March 18, 2016 Share Posted March 18, 2016 The most accurate consistent loads are all FL resized with .001-.0015 shoulder bump everytime. Link to comment Share on other sites More sharing options...
dauntedfuture Posted March 18, 2016 Share Posted March 18, 2016 What ever combination of FL, NS or NS with shoulder bump you use, you should not have to smack or forcibly close the bolt. You risk damaging your lugs. If, with what ever sizing system you use, you have inconsistent bolt close "feeling", this is normally an indicaiton of inconsistently sized brass. This happens. A FL size will normally bring all cases back to the same dimension. Link to comment Share on other sites More sharing options...
