Sir Ron I'm loading 77 grains of AA2230 behind the 450 TSX at 3.380 COAL
And getting right near 2300 fps MV, great load, Sir John. Works in any standard aught-six-length mag box I know of. Loading longer COL you have to add more powder and pay the price.
2300 fps MV with a 450-grain CEB brass FN zips through elephant or 10 feet of bison, when shot inside of 50 yards. (I am guesstimating 5 feet of MIB test medium equals 10 feet of bison, from tail to throat.)
A 450-gr TSX at 2300 fps Mv would be a longer range option, almost as good as a 404-gr Shock Hammer at 2500 fps MV, maybe 2600 fps MV to push the envelope.
You are spot on!
I'm shooting the 404 grain Shock Hammer @ 3.383" COAL in Norma brass Federal 215 primer ahead of 85 grains of AA2230 new manufactured powder for 2523 FPS. This load may be a bit over SAAMI MAP, but has worked fine in my rifle with repeated loads in the same brass
I got banned on another web site for a debate that happened on this site. That's a first
