Another point is the low expansion of the Barnes at .35 Remington velocities. Yes, they list opening at 1600-1800 fps, but firing loads at that level into expansion media shows only minimal opening, barely over bullet diameter. The long Barnes bullets reduce the already limited powder space, reducing velocity even more. For high velocity cartridges I love the X-bulletts, but I have to agree with GB here, the right jacketed bullets will doubtless give superior terminal performance in the .35 Remington. Try them if you want, but don't be surprised if jacketed bullets kill better in this case. Barnes didn't bother to even test loads in this cartridge in their manuals - there must be a reason for that.
