Wanted to hear from someone who has actually used these on whitetails, Would like an honest assessment of their performance. Have used 130 gr Berger hunting Vld's with varied success, from bang flop, to finding them within 50yds of where I hit them, to spending half a day trying to find them in heavy cover, (hard time, no blood trail). All dead animals but a blood trail is absolutely necessary in heavy the cover that I hunt in. Would the 130 GK's fill that bill?
