I just switched to the T/C yellow tipped 300gr shock wave this past year with harvester red sabot. 105grs of TTT7 send it on it way. No complaints. It is fatal on the receiving end of the rifle and most accurate of the bullets it tried. Prior to the shock wave I shot the Hornady 458 cal 325 gr 45-70 bullet. It was very good but tough to load, 54 cal. The TC bullet shoots a little flatter and is better accuracy wise. I do not like the lighter bullet weighs in sabot rounds( 240grs). I love the XTP bullets as they are toung and affordable, however the stubby shape makes for a lot of drop at distances beyond 100yds.There is no substiude to bullet weight since speed will never increase that much in my rifle.
