[QUOTE="Tripodmvr7, post: 1999154, member: 115545"] 1. You will see that lowering the Weighting factor gives you lower pressure. I do not touch that figure unless I have accurate pressure data from a reliable source and advise as to not play with that. 2. The case capacity is quite larger than the default 67gr. 3. The safest Node is No. 5 and 57K psi will ensure good combustion and case sealing. 4. Node 5 at 1,051ms relates to 60,6gr and speed of 3050fps.[ATTACH type="full"]219218[/ATTACH] [/QUOTE]
