I've put together a Seekins PH2 in 300win shooting 200g Accubonds at 3050 with RL26. The idea was a do everything load for Elk/Mule Deer. Although I've still got a little work to do, this rifle routinely shoots 5 shot MOA groups. I've read a great deal about their performance on elk but am looking for feedback on deer. I'm familiar with .308 165g performance and .277 140g performance on deer and elk (neither have exited on elk and in .277, exits on big deer are about 50%). On unwounded game, I won't shoot past 500 or so. I'm headed to CO and MT next week where shots tend to be 300+ yards. Any first hand experience on deer with an impact velocity window of 3000 to 2400fps?
