I was looking at Remington's site comparing the 150gr Core-Lokt's to other bullets they offer in .270 Win.
130gr Accutips come out of the muzzle with the same energy as the 150gr Core-Lokts (2702 vs 2705). At 500 yards, the Core-Lokts are down to 639 ft/lbs with 61.2 inches of drop while the Accutips still have 1243 ft/lbs and only dropped 37.7. The Core-Lokts come out of the muzzle at 2850, while the lighter Accutips come out at 3060.
I'm new to the long range game, but it seems like the big problem is the longer the flight time, the more tiny variations can have more effect on your bullet. The constant acceleration of gravity generates so much downward velocity with longer flight times that being consistent at long range gets progressively more difficult.
Tiny variations in MV or drag (altitude, temperature, pressure, wind) can create large errors. Combine this with effects of shooter error being magnified at longer range, it's quite a challenge.
Seems like selecting the best bullet for long range hunting comes down to minimizing flight time and having the right combination of energy transfer and penetration once inside the animal. AND...the bullet needs to be consistently precise out of the gun it's being fired from. Every gun handles bullet/powder combinations a bit differently.
So the 150gr Core-Lokts come out of the barrel slower, then loose velocity faster because of the blunt, rounded nose and no boat-tail. They're all done just past 300 yards in terms of velocity and energy. And that's exactly where I started having problems with them. Difficult to hit the target, and sub-par terminal performance once inside the animal. The 1000 ft/lb minimum on medium game is probably right on the mark. The Core-Lokts have 1185 ft/lbs at 300 yards and 872 at 400.
On the other hand, I never had a problem from 50 yards to 250 yards with 150gr Core-Lokts out of the .270. Any problems at that range were shooter error (me). The Accutips could not have done any better, and may have experienced problems where the Core-Lokts performed perfectly. I've never had "pencil-through" or inadequate penetration due to bullet blow-up.
You're right, I can't complain one bit about the 150gr Core-Lokts from 0-250 yards. And a 150gr bullet with low drag and good terminal performance might be THE right choice in the .270 for longer range, if I can get adequate MV.
Matrix offers high BC 165 and 175 gr for .270. Not knowing much about reloading and what's possible with .270 Win (case size, max pressures, different powders etc.), I've got a lot to learn.
