[QUOTE="KH_Outdoors, post: 3047031, member: 123559"] Got out and ran my initial charge weight ladder from 56 - Pressure. I'm pretty stoked with the speeds I'm seeing with N560. Also notable, every round landed inside of a 1" square at 100 yards. Most of them under 1/2" untill it got closer to pressure, that's promising! Velocity- N560/125 CR workup 56 - 3123 56.5 - 3105 57 - 3137 57.5 - 3156 58 - 3194 58.5 - 3205 59 - 3246 59.5 - 3263 60 - 3300 60.5 - 3342 - *heavy bolt lift & click* 61 - DISCONTINUED From here I'm going to back off 1 full grain from initial pressure signs at 60.5 to 59.5 gr and start shooting groups. Probably 58, 58.5, 59, 59.5 and record velocities, looking at groups etc... Looking good between that 3200-3300 fps range! [/QUOTE]
