Hey guys, sort of new to the long range brotherhood. Used to reload a lot back in the day ( 20 years ago ) and hoping to get back into it and long range stuff too. I am currently shooting 140 grain boat tail ballistic tips in my stw ( tack drivers ) but all I hear about in the long range stuff is 168 grains from the 308 guys. Is that considered the best weight to reach out and touch someone in any caliber or just 308? Hoping to save a lot of time and money and not re-invent the wheel here, Thanks, Mike
