Sorry for the late response. I just got out of the hospital a couple hours ago..been t here since early yesterday morning. It does have a 1:16 twist for all I've read.If that Remington has a 1 in 16 twist, it probably won't stabilize boolits over 250gr.
Djones-Thanks for that offer. It sounds like one I can't refuse.
Hodgdon at one time, and not so long ago, also has data for cast boolits but that doesn't seem to be the case anymore.
