Im a big fan of Barnes Triple Shock for elk. Great bullet. Used Nosler partitions alot and worked well too. Any bullet works long as the shot is put in the right place or shot presentation is sutiable. I always hear people saying the bullet didnt retain enough weight or mushroom properly, my moto is if your able to recover the bullet. Where did the bullet fail during the animals death?
I have used Swift's A-Frame for a few years. To me they are one of the best for Elk. Used to use Partitions but got tired of them going to pieces. I shoot 300 Win Mag 165gr. Swift. Of course Barnes' are pretty tough too. Lived in Wyoming for 18 beautiful years and was fortunate to have harvested 14 elk.
I have always (since 1990) used the Nosler Partition for Elk. I hunt a private ranch In Northern New Mexico (Chama), and shot a 5X5 the first year, and have shot a 6X6 every year since. The Nosler has always expanded well, leaving a large exit wound, and the Elk rarely moves far after the shot (most have dropped right there).
I use a 210 grain bullet in a .340 Weatherby.
You didn't tell us what you are shooting it in. A PSP. I assume you mean a Rem core lock? What cartridge? A 180gr core lock from a 30-06 should do fine but if I were using that light a bullet in a 300 mag of any kind, I'd go to some sort of premium bullet. Somewhere in the neighboor hood of 2900 fps muzzle velocity, cup and core bullets start having greater likelyhood of problems. I think more important is the impact velocity, it has to be. Never seen a study on that so I just stick to the 2900fps idea, above = premium, below = cup and core. As I never shoot magnums anymore, I use cup and core for everything but, I also use the heavier for cal bullets. The one exception to the rule for me is in my 25-06 but I never shoot anything bigger than deer with it. Still like the 117gr bullets.
By the way, PSP refers to the shape of the tip of the bullet. Pointed soft point. It has an exposed lead tip and rounded a bit more than a spitzer.
Don, Currently I use 150 gr Federal Powershock in my.308 for deer and have had outstanding results. I have a trip planned for 2ed rifle season in Oct. in Colorado and I'm working on a load for my new .280 . I want to select a bullet type that would be effective on either deer or elk. Although the psp's have done exceptionaly well on deer I was concearned that they may not be tough enough to give proper penetration for elk. I'm starting with 140 gr and working from there. Most "premium" factory loads are ginving me anywhere from 2900 to 3000 fps on the charts. Of course with all of this being said, bullet placement trumps anything else.
First make sure your gun is safe, remove the bolt and clean your barrel from the chamber to the end of muzzle. Clean the barrel using butchers bore shine until a patch comes out white. Run a total of 5 separate patches soaked with denatured alcohol through the bore and let dry for 30 minutes. Insert a cleaning rod with a jag and a dry patch into the neck of the chamber. Make sure it will stay there through the next process. Now using another cleaning rod, install a patch that has been coated...
