[QUOTE="Black Diamond 408, post: 283071, member: 1563"] Kirby, So far i have been loading the same 5 cases, got 7 loadings on them so far. This short fat case seems to be stronger than any brass ive seen. I have not found any load that will pressure the case, im almost out of room with H1000 and round primers after firing. Pockets are just as tight when i started. When you shorten a case that much the whole case, except for the neck, is much thicker than standard brass. With the large case head and short length of the case it seems to produce less pressure. A friend of mine has a 300 Dakota and he is using 85 of H1000 for a top load, 210gn bullets. I started out to build a 300 Lapua, but what is the fun with that? I wanted somthing different that no one has. I'ts a lot of work to get the brass made but thats part of the fun. Once the brass is made it looks like you will get a LOT of reloadings from it. The goal was to have a 30cal. long range pistol shooting heavy high bc bullets over 2700fps. From the early results 2800 will be no problem at all. If you compare a Lapua case to a cheytac case, but make them both the same capacity as the Lapua, the cheytac case will be heavier built. Everyone knows that a short fat case has less bolt thrust pressures. Powder ignition is more consistant, ES spreads are running 4-6 for the fired cases, forming cases they are running in the 20's Once i get some of the 180 and 210gn HATs i will have more data to post. I'm assuming the 8 twist is too fast for the test bullets i have been using. I might get a 10 twist barrel for it so i can use some other bullets as well. This is just a new toy for my box. [/QUOTE]
