usmc0331 , your right the about getting the same velocites actualy he should be getting higher speeds with the standard 284 than the 6.5-284 if both shooting 140gr bullets ,in fact he shouyld be able to get in the 2900fps range with 160 class bullets and 2700 with the 180's , now a 180gr Berger VLD launched at 2700-2800 fps hase some very impressive ballistics especialy at 800yds and out , the 162gr Hornady A-max would be an awsome deer bullet to 1000yds launched at 2800+fps. and using the better 6.5-284 Lapua brass and necking it up would make it even better than using the old winchester stuff. Not to sure he would be 3x's the barrel life but very likely 2x
But the question was about the 6.5-284.
So If you have the 6.5 barrel already
you just want a 6.5 caliber
or what ever reason you have then the 6.5-284 is a good round
If you don't have anything or any specific wants then maybe tell what it is that your wanting to get from a new round?
