I recently had high velocities (across a Caldwell) due to it being too close ... a bare minimum of 10 feet is needed ... 20-30 is ideal, then back into your muzzle velocity with a ballistics calculator.According to GRT using standard 6.5 PRC case water capacity, your bullet at 2.950" with 55.6g RL26 and a 143 eld-x should be around 2942 fps at the muzzle.BTW - for the standard default water capacity, it shows max charge of 58.7g yielding approx 3116 fps ... so, if you happen to have cases that are a bit on the smaller internal volume end of the scale and are seeing pressure signs showing up at or just above your current charge, then 3100ish is not out of the question ...Tim</blockquote>
