[QUOTE="Rich Coyle, post: 1294312, member: 70559"] A starting note: These were fired [B]before[/B] I discovered and started correcting seated bullet run out. The objective of these groups is to compare full length resized .223 Remington cases to cases which were neck sized only. On the full length resizes cases, I pushed the shoulders back about .001" so they would fit the chamber with absolutely no bolt closing resistance. A Stoney Point over all length gauge help with this task. I sized the necks in a Hornady .224 neck sizing die about .100"; which was plenty to hold a 52 grain JLK bullet since it was seated in only .080”. All full length cases were resized utilizing the Hornady New Dimension Custom Grade dies. The barrel cooled quickly between groups because the temperature was 30 degrees when I started shooting and edged up to 35 degrees by the conclusion. This is an out of the box Savage rifle, the best four shots out of five are also included. The rifle was cleaned and three fowlers fired prior to the testing. H 322 charged full length resized cases produced a velocity of 3,548 fps. The group measured .579" with 4 @ .415". The neck sized cases generated 3,586 fps and a group of .844" with 4 @ .486". H 335 powered full length cases produced 3,558 fps and a flyer group of .784" with 4 @ .379". The neck sized speed was 3,607 fps and the group was .527" with 4 @ .473". AA 2230 loaded full length cases pushed the 52s to 3,531 fps, and the group was .604" with 4 @ .337". The neck sized cases did 3,580 fps and made a group of .445" with 4 @ .250". BL-C(2) full lengthers flew down range at 3,532 fps and made a group of .671" with 4 @ .406". The necked sized load dashed away at 3,574 fps making a group of .491" with 4 @ .394". The average for the full length groups is .6595". On the other hand the groups for neck sized averaged .5767" for a difference of .0828". [/QUOTE]
