Great shoot'n Jay,
You may want to give the the loose T7 a try if'n you get a chance, as from my own experience, a load of 80-90 grains depending on the sabot that t/c is using with the xtp's in your batch will drop that group size even smaller!! Not that reducing a group that nice would mean much for deer, but It's always nice for piece of mind (or bragging rightswith your buddies for that matter).
Good luck and good shooting!!
