I will be going to Colorado this fall for my first elk hunt. I am new to big game hunting. I have been a birddog guy all my life, but decided to give this a try. I bought a Weatherby Mark V chambered 300 weatherby. I will do as much shooting and excercise as possible this summer to get ready. The 180 grain hunting lodes go for $65 to $75 a box! I was wondering if it would make much difference if I shot targets with the 150 grain spire points instead. I can get them for about $45 a box. I figure that shooting targets at 100 to 300 yards will not make a substantial difference. I will shoot the hunting lodes closer to my trip. What do you think? Any suggestions would be appreciated.
