[QUOTE="RockyMtnMT, post: 1556842, member: 7999"] Several years ago when we first tried the 6.5 Ultracat we saw some huge pressure spikes when trying different powders. The only powders that we seemed to get much consistency with were ball powders. Powder bridging... I'm not sure, but this time around we will start with the LRT ball powder. Also now that we are making bullets we are able to run a much bigger bullet than we had available then. 40g bigger. Right now the test bullet is 1.835" and is weighing in at 169.8g. This is showing a 1.61sg at 3000fps and sea level with a 6" twist. [USER=2460]@Swamplord[/USER] the 1-7" twist shows a 1.18sg at 3000fps. 3500fps only bumps it to 1.24sg. So unfortunately the 1-7" will probably have trouble with this one. [/QUOTE]
