I am not even sure what you are calling a special long range rifle.You did not say what animals you want to hunt out west nor do you say what ranges you are expecting to shoot. However, you don't need to carry a rifle with a bull barrel and a lot of weight to make accurate shoots. Choose the caliber you want to use that is appropriate for the animal you want to hunt. I have not hunted out west but I am sure if you provide the information I mentioned that is not in your post there are many folks here who have hunted out west who will help you
