I have been doing a ton of reading for my next choice in rifle caliber for a custom build. There are so many choices that are good choices so it makes this very difficult. What I am looking for is a caliber that I can buy the brass for, is inexpensive to reload/shoot, and is accurate as all hell at 600 yards and out to 1000 yards and maybe further for punching paper and yet will be a good long range varmint gun also. I would like barrel life to be long lived. I am thinking of something like the 6mm br or the .260rem. Something like that but I am totally new to these types of calibers so I am not sure. I currently have a .17hmr, 22-250 and a .300wsm and all are great but I would like yet another rifle as I am addicted to this. I am looking to get some form of the .338 for very long range and some other cartridge for around 1000 yards and under. Thats where I need your help! Sorry for the newbie like question. I have done lots of reading but I just cannot make a decision.
