[QUOTE="thor447, post: 3655695, member: 24867"] Let me start off by saying, I realize this thread is useless without pics! I know, I'm sorry! I got some new Lapua brass and was planning on doing a new full top to bottom load development on the 6.5 Creedmoor. It's always been a pain in the rear for me because I have to travel about 45 minutes out to Lexington to be able to shoot it at least 100 yards, so in the past I'd always take multiple trips when trying out different powder charges or seating depths. I decided to make my experience somewhat easier this go round and I bought a Lee hand press. My thought was when I was testing different seating depths, I'd just load all of my ammo long, and take the equipment to the range and seat the bullets to length there, giving me much more flexibility and the ability to load additional sets to validate results. First off, let me say that any fears I had about any slop in the breech lock bushing of the Lee hand press were for nothing. There is zero play in it when tightened down and I was able to seat bullets with fantastic consistency with my Redding micrometer die. I loaded everything (very) long at home, and the first seating depth length I was going to test was loading the rounds to max mag length, in my case it was 2.176 CBTO with the 150gr SMK's. In the past, the best load I could find was well over mag length which stuck me with a single shot rifle when using those 150gr SMK's. I was hoping to find something comparable in the mag length or under range. I loaded up 8 at 2.176, used three to foul the bore a little bit, and shot a 5 shot group with the 2.176, which (according to my notebook) grouped at 0.55" at 100 yards. Pretty darn good for my sloppy shooting! I started seating shorter in four shot groups, all the way down to 2.136. As luck, or irony, would have it, every single group of four shots was worse than my first group of 5 shots at max mag length. I then loaded another 10 rounds at 2.176 and did a full 10 shot group which measured 0.64". All of this was just using a middle of the road powder charge of H4350. I did not bring a chrono on this trip. Next weekend, I'm going to head out there and will do some powder charge testing with everything loaded to 2.176. Normally I'd always developed a load with charge first, then seating depth. Another member on here mentioned that they did it with the seating depth first, then the charge. I looked elsewhere online and found that it was a hotly debated topic, but several people prefer the seating depth first, so I thought I'd give it a try this go round. I just found it funny that the first seating depth I tested was far and away better than anything else that was tested today. Next weekend I'll have some chrono results, and will upload pics as well.
