Has any one had any experience with the 350 grain Swift A-Frame bullet in the 45-70. I talked to a fellow at the factory in Kansas a few days ago and he was real hyped about it...it's a new bullet for them. He said that it was designed to work best at 45-70 velocities...around 2000-2100 fps. I'm looking for an all around good bullet and load for the 45-70, something that will work on anything including big bear. Maybe a bonded core 400-405 bullet would be better...something like kodiak bonded core bullets?
