I shoot H4895 with the 120TTSX using a charge near their listed maximum (Barnes manual). I was as high as 3,000fps in a 20" factory barrel, but backed it off a few tenths to play it safe at the mid 2900s (kid's rifle). Also shoot CFE223 in an 18" carbine with a charge near Hodgdon's listed maximum. It has to be a bit warm at 3,100+, but it shoots well so I haven't changed it. I've tried Big Game in a few rifles with 120gr bullets but could not get the accuracy I was looking for.
