The .270 and 130 gr. bullets go together like grits and eggs! I load 130gr. Barnes TTSX's for 3 different rifles and those fellas LOVE them! Im going to play with the Barnes 110gr. bullets after hunting season this year and see how they look on paper.
If you're lucky enough to be on private land and can leave your stand up during the off season you can tie an old piece of cloth or something of the sort to your stand. I like to use an old camo bandana that I have. That way the deer get used to the movement and eventually don't bother even looking up when there is slight movement. This may just give you the time to draw your bow or raise your gun without being detected.
