I like reading all the "discussion" on why a .35 Rem has been a killer, same with a 30-30. There is little doubt that those cartridges used by an experienced hunter, who knows their limitations and stays inside those parameters, will kill Elk.. I made a post earlier that it takes tissue destruction and blood loss to achieve a kill. If you can get a good bullet (read that expanding) into the heart lung section of an animal, they will die. One of the "legs" of creating a quick kill, is to place enough energy into the animal to create a LARGE wound channel. The larger the wound channel, the more tissue destruction there is, the quicker the kill. The larger the diameter and weight of the bullet and the faster it travels, assuming of course it is a good hunting bullet, the more energy it transmits to the animal. The more energy, with excellent expansion, the more tissue destruction there is. The more tissue destruction there is, the more blood loss there is. This all translates to a quicker kill. All "Big Game" cartridges will kill IF they are used within reasonable ranges for their "power". Having said all that, no hunter can be absolutely sure that once he sees a BIG Bull Elk, that it will be a "classic broadside shot" at your chosen cartridge's reasonable range. I believe that is why when you may be spending $10,000.00 for a private property, guided Elk hunt, you will generally see some form of a large magnum cartridge with a high quality bullet that can both penetrate and expand, WHILE holding on to most of it's original weight. I think that those type cartridges, with a well placed shot will bring the animal down quickly, at most ranges.. I also think that the cost of a rifle and good ammo is a pittance, compared to the $10,00.00+ you just spent on a hunt! Why not just plan for the hunt, get a really good rifle / cartridge for Elk and either load up or have excellent ammo loaded up to allow you to have the highest possible chance for success!
