..........I don't THINK anyone in the world can say for certain.........it depends on your brass consistancy,chamber straightness and dimentions along with your press and die straightness and matching dimentions to your chamber.....SOME guns even shoot Full Length sized cases BETTER-more accurately due to variables in the mentioned factors........just size the cases with good lube and in straight dies with a polished expander if the dies use one and then test the concentricity of the loaded rounds with a gauge to compare them with your neck sized barss AND/OR just shoot them and compare grouping......the single shot guns are usually reccomended for full length sizing anyway by most sources but individual guns are chambered better and will take neck sized brass.....HTH..good luck and good shooting-loading!!!

How about just bumping the shoulder back a bit rather than full resizing?

josebd,

I have never had to do more that neck-size cases in any of my guns. I keep the pressures below maximum on most of my loads (the only exception is a straight walled pistol case). If your cases are expanding beyond chamber dimensions I would look at the load and see if it can be dropped a bit to prevent future problems. To correct your tight fit it might be necessary to "bump the shoulder back" with a full length die.
