I want a caliber for long range varmint hunting and target shooting. Now i want something that will be pretty comfortable taking shots from all day. I dont want a 223. I was thinking of possibly making it customed or even customizing some of it. Originally i wanted just a straight up normal 22-250 Remington which is still a great caliber but then i realized i wanted a gun i could hunt varmints out to long ranges, and target shooting at even longer ranges. After talking with my neighbor and his friend that i bought my last gun off that does a lot of reloading and does 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. I know its no long range caliber but it can be good for pretty decent ranges. 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" hart 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?
