I loaded up two batches
350 Swift A frames
350 Barnes TTSX
The A frames averaged 2350 fps at the 15' mark
The TTSX averaged 2210 fps at the 15' mark
The long TTSX had me concerned about case capacity so I used less powder than the A-frames. This is in the 20" Ruger Alaskan.
The TTSX are wicked accurate and shot a great group at that speed. Should I try and and mess with a good thing and squeeze more powder into that case? The recoil was just fine for that load. There is just a fixed 4 scope on the rifle so I'm not expecting shots past 300 yards.
