Chronograph died in it's sleep over the past few months, while my rifle was being rebarreled. I need a charge range to work up to while I research a suitable replacement. Any suggestions would be appreciated. My goal is 2950-2990 fps from my 26" barrel. My new Mike Rock barrel seems to really like Re22 as every load with the exception of starting charge have been sub .5 moa. Last load tested was 67.0 gr with no pressure on primer and case miked .552". My new barrel has no freebore and 2.864" COL with the SMK190 is to the lands. My last barrel was set up for Barnes X so I could seat the SMKs to 2.96" COL. Please post if your data is for plain or molyed 190s. Thanks for any help.
