Mine is built on a Mark X long action w/23in Douglas. I have every bullet I think they make except the 200gr TTSX. and that's the one I want to try. I may just buy those and call it done for deer and hogs here in Texas.It's long enough to have decent BC and looks wicked. I think I can get it to 2750fps w/N201 in my 23in barrel. Should be good to 350yds. powdr
