14" contender barrel currently using 200 gn interlock RN with Remington 9-1/2 primer and H4198 powder. Pushed in to the cannelure and a little bit of crimp and it's an acceptable OAL.
Book says min 27 gn max 30.5 gn. 27 was a joke. Incremented to 30. Still a joke. Outside of neck was carboned and primer was round and possibly still protruding on some. Highest velocity I saw from the Caldwell ballistic precision was 1814. Tried to get a reference from some factory leverevolutions but couldn't get anything but erroneous readings from the FTX bullets. Don't know if it's the bullet or a powder/ debris problem with those shells but any suggestions that don't require buying a new speedometer right now would be greatly appreciated. Also suggestions on what to do with the load.
