Pace Maker-----I use the same rifle as you--Model 700. I've used 180 psp "Core-Lokts" for years. Never had a problem with them on any elk I've shot at or guys from my camp. We all shoot 06's & site in with the same ammo. 180 Core-lokts. We've recovered a couple of bullets---they were text book "mushrooms". IMO they were made for the 30/06. Correct me if I'm wrong but back when the 06 was the speed demon---it was having bullet problems---fragmenting, no penetration. The "Core-lot" was the answer to that. The velocity of the 30/06 has not change----but now---we have pushed the envelope again-----IMO you can't push "Core-lokts" @ 3000 fps. So now to handle the faster velocity of "Mags"----they are making bonded bullets.

FYI---I've also killed elk with "Core-lokt" round nose, Win PP round nose & the Hornady "Interlock" spire point------all bullets were 180 grain. I could not tell the difference----most shots were behind the shoulder, a few on the shoulder & a couple were quartering away. All shots were under 250 yards---most @ 150. We are talking about 30 elk taken-----15 by me personally & another 15 or so from guys in my camp.

Thinking of using Hornady Custom 180 grains this year. CB
