[QUOTE="Welderboy11972, post: 1291994, member: 91394"] Hey guys, I've come to pick your brains again. In my quest for the most accurate/consistent reloads I can achieve, I have a slight issue here. I'm looking for advice as to how to fix this. A shooting buddy talked me in going up to Rayner's Range and shooting in there long range match a few weeks ago, now I'm hooked. I wanted to fine tune my reloads to get the best case/powder/bullet consistency. I cleaned my barrel really good, loaded up some rounds and headed to the range this morning. Rifle is a 25-06 LR, 26" barrel (all I have to shoot at this point) Brass is norma ( all trimmed to 2.485. .001 over book and sorted) fl sized in redding dies, with out sizing ball, I neck back up with the Sinclair mandral. Bullet is 115gr NBT..setted .030 off the lands( all weight sorted and ogive to base sorted) powder is retumbo. My 5 fowler shoots (group 1) This group consisted of brass with fairly loose primer pockets and bullets that fell outside of the weight/measurement standers I've set ( under 115gr/above 115.5gr...under .570"/above .571" base to ogive). Brass is trimmed to 2.485 it has not been neck turned. Group (1) 58.7grs / .030 off the lands 1..3220 2..3220 3..3212 4..3212 5..3220 For groups 2-4 the only changes that were made is I turned the necks on the brass, driffent powder weights ( 58.5, 58.7, 59) and I used my sorted bullets. Group (2) 58.5gr....030 off the lands 1..3212 2..3197 3..3182 4..3197 5..3189 Group (3) 58.7gr....030 off the lands. ( same load as my fowlers) 1..3189 2..3205 3..3205 4..3197 5..3197 Group (4) 59gr...030 off the lands 1..3197 2..3197 3..3197 4..3212 5..3220 With all that said..what I see is, I get the best groups with a velocity of 3212-3220. With the only thing I changed between group 1 and group 3, is I turned the necks on the cases and I used more consistent bullets. I know that by turning the necks I changed the neck tension on the bullets. Witch is why I'm probably seeing a difference in the velocitys between 1 and 3. I didn't resize the cases after I turned the necks. My questions are... Should I shoot the remaining neck turned cases, tumble, size, and everything will go back to normal? ( group 1&3 match) Should I just resize the remaining cases? Should I increase the loads up more (59.5gr/60gr) untill I get the velocity back up to around 3220? Is it possible the with this bullet/ powder, it's not liking a fowled barrel? (After 10 shots) Is it possible I've somehow cause neck runout when I turned the necks? Thanks for any insight you can give me. For some reason it's not wanting to upload my pics. I'll try to get them up after this post [/QUOTE]
