Guys, I'm trying to work up a lighter load for my Roberts. I hunt deer in the hill country of central Texas. These deer are medium to small in size, and my ranges are usually between 100-200 yds. Do ya'll think a 85 grn BT @ around 3200 would work ok? I know the 85 grn are supposedly for smaller game, but I have had good luck with 55 grn. BT's out of my .223 on deer out to 200 yds. What do you think?
