The 1-10 is not gonna run the 105s.
It'll run run "standard" 100s, 95gr NBT, and the various "80 somethings".
That is plenty good for mule deer and smaller, IMO. I have shot a ton of deer with various 243s. 100gr SGKs, 85gr Barnes, 100gr Hornadys, 100gr Win PPs, Partitions, I could go on. They all take deer quick and clean......
