I am helping a friend get into mid-lr shooting (lets call it out to 600 yards). This is more of him wanting to learn, practice, on steel, and just have a chance to shoot more with the idea that 600/700 yard practice will allow him to be comfortable on those 3-400 yard shots while hunting.

Anyways, he is shooting a 10twist 24" barrel 270 Winchester. I love the cartridge, but have never tried to wring it out much as a LR round. However, with the great selections of new bullets and powder, I have pretty good guess we can help transform this round a bit.

Re26,

145 ELD-X.
150 Nos LRAB
140 Berger Classic Hunter

The 150's pushed at 3k with .591 BC are intriguing, as is a 145 at that speed. I want to work up a load with a "killing bullet" so he can practice all summer and not change anything up going into the fall. Thoughts? Any other bullets to consider?

(Side Note, scope is a 6x ss - so we will be working on dialing/using reticle for wind)
