First of all, you were lucky that you didn't get a multiple explosion in your mag tube using a pointed bullet. Use only flat/round nosed bullets in a tubluar magazine. Secondly, the Rem. 200gr. PSP-CL is designed for 35Win./35Whelen velocities, that's why you weren't getting good expansion/erratic performance in the lower velocity 35 Remington. Get yourself some of the Remington 200gr. round nose bullets that were designed to be safe in a tube mag., and to expand at 35 Rem. velocities. The good old Rem. 200gr. RN bullets have been bringing down black bears for decades and are well respected.
