I could use some advise, my sister and I will be deer hunting this year in SE Wisconsin. This will be our first year. Where we hunt is public land Kettle Moraine Southern Unit, our shots will be limited to about 100 yards or so except maybe along the power line route but we aren't allowed to shoot using those lanes. I have 2 rifles at this time one being the Vanguard series 2 in 257 mag, the other a Remington 770 bolt gun in 300 win. mag. that gives me .78 Inch groups on the bench. Freehand I can only get a best so far, only 80 rounds down range so far, of 1.1 inch. My sister will be shooting my Vanguard since she love the thing so much, I will be shooting my 300. My main question is this: I'm sighted in with the 300 with 180 grain Barnes TTSX, under say 50 yards or so I have read about bullet blow up. Am I going to have issues with short range on the 300 with this round? Should I go heavier say 200 grain?
