I dont own a caliber between a 22LR and a 7mm rem mag. I want a caliber that i can use for long range shooting, as well as varmint hunting. I do a lot of varmint hunting, unfortunately i have to use my buddy's guns because of my caliber choices. It is time for me to get my own. I want a caliber for long range varmint hunting and target shooting. After talking with my neighbor and his friend that i bought my last gun off, they do a lot of reloading and long range shooting i think i might just want to stick with a popular caliber like a 243. win or even make it a 243. AI. That way it will buck the wind better and have a little more power way out there compared to some of the smaller 223, 204, 22-250 will. I dont know much about long range shooting seeing this will be my first long range rifle. I would be really interested in making a custom rifle but i dont know where to start. Help please. I was looking at a Defiance action, a 26- 30" hart barrel or Kreiger barrel (somewhere around a 1-7 to 1-9" twist) , a Macmillan A5 stock (maybe), Jewel Trigger and no idea from there? any ideas? any other stocks out there that work good? Recommendations on twist rates? Please suggestions. For target practice, the majority of my long range shots will be at the 600 yard mark. I will obviously like to stretch it out as far as i can possibly keep it flying. I would like to try for 1000 yards but the 600 yard mark is my main goal. For hunting, it will be pretty much anything that walks into my cross hairs that im comfortable taking the shot at. Right now is about 350 yards, with my buddy's 223. rem, and about 400 yards with my neighbors 243. win. They both have factory rifles. I would like to shoot something around a 87grain V-Max, 105 grain V-Max, or even try them 115 grainers. Most likely will be 87 grain and 105 grain and see which works best.
