You are right, Moose. Back in the late 50's good bullets for the .348 were hard to come by. The 35/348 was a good answer because Nosler had 358 partitions.

Now-we really have a choice in bullets. I have a 450 Alaskan and a 450 Fuller on pre-War early 71s.Along the
Kenai and in other serious brown bear country, the 450s are the way to travel. Bear spray may not work.

The 348 Ackley Improved is another good one. It pushes a 250 gr Hawk at about an honest 2375-2400 FPS. I killed a nice Alaskan moose in 2007 with that cartridge using a 270 gr Hawk bullet. Great sectional density for the big stuff. With the Woodleighs-Swifts-Hawks, the 348 Ack Imp is
starting to shine in the Model 71.
