[QUOTE="RockyMtnMT, post: 1254506, member: 7999"] Hello Kevin, I am going to have to go read my front page again. I hope I did not say that our bullet has the bc of competitors heavier bullets. That is not likely. Our bc's are comparable to other bullets of the same weight give or take. Not the best not the worst. As far as loading you can generally use load data for like weight bullets very well. The PDR makes them have a little less pressure than conventional lead core bullets in most cases. Definitely less pressure than grooved mono bullets, and probably a bit more than drive band/bore rider bullets. Use conventional published data and work up from there. Most rifles I find to hit pressure a couple of grains over published data. Still work up as every rifle is different. I look for load data that does not show compressed loads with the given powder, but I like to finish near 100% load density. The method that I use is to work up in 1g increments one shot at a time with a chronograph. I like to do this at 2 or 3 hundred yards. I watch the target looking for a bit if a node, or tight group. This is not the determining factor for the load though, just good info. I will load up till I find the first signs of pressure and then back off 1 or 2g. Then I load for group with that load. Very rarely do I find the need to tweek the chosen load for group. They pretty much always shoot better than I can. Reason for the chronograph is to watch vel. If it is way too high so is pressure. With most rifles I get 100fps give or take more vel than published data. Again every rifle is different. This does not always happen, some rifles are just slow. Another thing I have learned is to clean the rifle completely before you start. Our bullets do not seem to copper foul at all but rifles with heavy fouling seem to cause trouble when we start load developing. So get all the copper and carbon out before you start. I like Tetra Gun. Use your favorite. You should be able to get load development and zero done in less than 25 rounds. The powders you have should work. If you can find H4350 or IMR4451, those would be my go to. I will bug one of my best buddies that has done a bunch of work with the 166g Hammer in 30-06 and get his load. Steve [/QUOTE]
