RE: Max COL 300RUM you would safely load
I don' t have any feeding problems either. I also don' t think the recoil is that bad. I got my Chrony working again and 101grs of Retumbo averaged at 3365fps with the 180gr Hornady SST. My OAL is 3.665. I haven' t seen very many used rifles in the Ultra mag line around here.
