[QUOTE="chuck plissken, post: 916226, member: 42096"] ok,Im having a rifle built and just loading up some test/break-in loads with Sierras manual. Im getting a compressed load very soon at COAL of 3.580. Im curious if the manual really wants this to be seated longer cause it doesn't seem right to me. powder is 3 years old and another pound I have is less than 1 year..hope the lot of powder isn't different? I started at 84.0,85.0,86.0 with 5 loads in each to start and break-in along with chorno results. I was gonna stop at last 5 loads of 87.0gr which would be a total of 20 rounds for a first time out and recording data. But...87.0gr is just where it started to "crunch" or feel compressed... Sierra lists 93.9 as max loading for this combo at 3.580"!!! Im wondering if anyone will chime in on similar issues with this manual/combo. Im gonna load some using "off the lands" method once I receive the rifle and break-in. Im sure I will be able to squeeze more in there. thanks for any help or reassurance :) [/QUOTE]
