[QUOTE="MudRunner2005, post: 992862, member: 12995"] According to the Berger manual for STW with 180's and Reloder 25, you are looking at.... Start: 69.5 Max: 73.0 But remember, those are just guidelines, but approach max loads with caution to see where your gun starts exhibiting pressure signs. I use IMR 7828 SSC in mine for pushing the 180 Hybrids. I've worked up to 71.0 and I'm just at 3,000 fps with no pressure signs. So, when it becomes cooler and more like fall, I will continue working up that load to see where I max out pressure and velocity at. I'm hoping to push 3,100 fps...But we'll see. [/QUOTE]
