Redgum Posted December 31, 2011 Report Share Posted December 31, 2011 (edited) Quick question on resizing 308 once fired brass,started off with some once fired from another rifle so full sized and had some really excellent and consistent results, now I have started neck sizing these very same cases. With the 243 there is quite a noticable differance in accuracy between neck and full resizing but with the 308 it seems to be the opposite, neck sizing seems less acurate than the fully sized. I'm loading 150gr sierra gameking and am wondering if its a neck tension issue ( using Lee collet die which are usually pretty good) The Tika likes a 2'800 AOL which does'nt leave alot of bullet in the case. There is a high possibility its pilot error, but just thought I would ask anyway. Happy Newyear to you all.

Imperfection Posted December 31, 2011 Report Share Posted December 31, 2011 I've tried full length against neck sizing similar 303 Privi and neck sizing wins in accuracy.I too use a Lee collet die (in a deluxe set) and i set the tension quite hard so it really grips the bullet.

phaedra1106 Posted December 31, 2011 Report Share Posted December 31, 2011 My Steyr .308 prefers full length sized, using Lapua, Federal and even some Prvi cases and the Lee factory crimp die. Quote Link to comment Share on other sites More sharing options...

kent Posted January 2, 2012 Report Share Posted January 2, 2012 I think any noticable difference between neck and full length sizing in terms of accuraccy are generally down to the die quality or setting up of them. I used to feel differently like many others but it just aint so that neck sizing shoots tighter than full length, all things being equal that is Quote Link to comment Share on other sites More sharing options...

Neck sizing is obviously easier on the brass though full sizing 308 does not seem to lengthen cases as much as it does 243, only time will tell how long the cases will last. With 243 I have been neck sizing after initial firing in my rifle for 5 reloads, then full size once and back to neck. I have had dented necks from being over excited with the case lube but some of my early federals are well over ten reloads. Quote Link to comment Share on other sites More sharing options...
phaedra1106 Posted January 3, 2012 Report Share Posted January 3, 2012 Only problem I've had with Federal cases are a few of the primer pockets are a little less tight, not loose just a lot easier to prime than the others. Quote Link to comment Share on other sites More sharing options...
