ive used Swift bullets with great success in cartridges such as the 7x57, 375 H&H, and 416 RM. but i havent tried them yet in low velocity cartridges such as nitro express cartridges. im considering them for the 450 NE 3.25" (assuming they will regulate) and the 505 Gibbs cartridge. but i wonder if the very low velocities these cartridges produce will properly expand the tough A-frame bullet before it hits the vitals on a typical broad side shot on a buffalo?
the velocities in question are:
- 500gr .458" at 2050fps (impact velocity will likely be around 1900fps)
- 570gr .505" at 2150fps (impact velocity will likely be around 2000fps)
im concerned the A-frame will actually be too sturdy assuming it doesnt hit a major bone. im sure the bullet would fully expand by the time it reaches the off side of the animal but that doesnt mean much if it wasnt expanded when it passed threw the lungs/heart. in all of Swift's pictures it shows almost no expansion on the low end of the velocity spectrum which isnt promising.
thoughts?
