[QUOTE="JackinSD, post: 763478, member: 40641"] My experience with 105 AMAX and H4350 has been exceptional. I am running .15 off the lands. Quite a bit more jump than you are at .018. That is neither here nor there, just a difference to be mentioned. I know you have done load development before, but I will hopefully help you out a little. That is a big maybe. Looking at your developmental loads, I would decrease the charge distance to .2 from your current .5 grains. Why? I found a great difference in load development (ES and accuracy) with even this small charge distance. Also, it will give you a little more safety in working up to a max load that still hits your accuracy node. I went with my middle node, which I found at 39.2gr. I went with the middle node just to give me a little better barrel life and still have decent velocity (2965 avg). I intially used a chrono and 100 yard distance to find accuracy and velocity nodes. I then checked for accuracy at just over 400 yards (407 exactly). I found two loads that were very very close to one another in performance(39.8 was the other load). I went with the slightly slower load for the reason described earlier. As far as H4350 goes, I have no complaints whatsoever. My load was developed when it was 65 degrees out and has held very true to 10 degrees. I have not done much shooting with this load at hotter temps during the summer. But, my load was made for hunting during the fall/winter. I'll know more once the summer months get here. It is always a trial and error process with more errors than not. I hope you find the non-errors. [/QUOTE]
