First thing, I am not a reloader and know nothing about it so bare with me.
With the ammo situation we are in, and not being able to easily find any variety you'd like to have, I have loaded up on some factory soft point stuff that I'd like replace with a ttsx. Its 270 win ammo that I would like to try the ttsx on wt deer instead of fed fusion and other 130gr soft point type bullets. I have a friend or 2 that does some reloading and I'm curious if its "easy enough" to pull bullets and place a new one in.
Not sure that you really need to do this at all. The TTSX might make sense for shooting elk or hogs but pretty much every 130-grain bullet ever developed for the 270 Winchester was developed specifically for hunting white-tailed deer. You could end up moving backwards.
