I posted a similar thread a little while ago, but I now have a bit more experience and wanted to spark some more discussion on the matter.
A Remington 700 in .270 win, used for hunting elk at ranges that vary from 10-15 yards all the way to 100-150 yards, with a very unlikely possibility of 200-250 yards.
The back story:
Went to do a little shooting with my dad this last weekend, I had just got my new scope mounted and wanted to test it out, and my dad had just acquired a Winchester Model 70 featherweight in .270 win. We weren't at an official range, just out shooting in the snow. We setup our target at about 40 yards, the target pinned to a tree stump. We started shooting with 150 grain soft point ammo, and ran through roughly 30 rounds until we exhausted that supply. There was damage to the stump, and we were both shooting fairly well (aside from a poorly mounted scope on my rifle, that's going to be fixed this weekend). Then, we switched to 130 grain pointed soft point ammo, and the difference was stunning. The damage to the tree was extraordinarily higher with the 130s than with the 150, with each 130 showing visible and shocking damage to the tree. We actually removed a rather thick limb from the stump with only about 15 rounds, and the surface of the tree expelling chunks with every shot.
So I started doing some research, and sticking to the ammo brand I wish to use while elk hunting, Remington Core-Lokt Express, I compared some balistics.
130 grain PSP- Muzzle velocity 3060 fps, Muzzle energy 2702 ft lbs.
130 grain PSP- Velocity at 100 yds 2802 fps, Energy at 100 yds 2267 ft lbs.
150 grain SP- Muzzle velocity 2850 fps, Muzzle energy 2705 ft lbs.
150 grain SP- Velocity at 100 yds 2504 fps, Energy at 100 yds 2087 ft lbs.
Here's link to the ballistics I'm using, hope it works right.
So, what this all boils down to, is that I liked the damage I saw with the pointed soft point ammo rather than the soft point, and Remington doesn't make the Core-Lokt .270 150 grain in PSP. I also like the balistics better on the 130 PSP, higher velocity, better energy, and less drop as compared directly to the 150 SP.
Are the visible benefits of the 130 grain PSP (ballistics and seen damage) enough to take down an elk? Or is the 150 grain SP still the better choice due to the increased mass of the bullet? Do the PSP rounds have a better expansion that the SP?
From what I see, I'm really leaning towards the 130s, but I don't want to risk leaving an animal wounded by a round without the mass for a clean kill.
So there it is, as logical and precise as I can be right now, what do you all think?
Also, I know the .270 is a tad on the small size for elk, I don't wish that to be part of this discussion, as I will work more on shot placement. I don't wish to use a different ammo simply because the Remington ammo shoots very nice in my gun, and I'm a cheap bastard who doesn't want to spend a bunch of money on expensive ammo that will work roughly the same as the cheap stuff.
Any input you all have will be appreciated!
