if you have a production barrel i wouldn't even consider them. with solid copper bullets,the fit of the bullet to the bore is critical for accuracy.jacketed bullets will swage into the bore making a near perfect fit,that's why it's easier to get them to shoot.solid coppers will not do this.also, if the muzzle end is any bigger than the chamber ,you will never get them to shoot.this is why most of the solid coppers are a rib or banded style of bullet.it allows them to be more forgiving in regards to the bullet/bore fit.this is why Barnes copied GS Custom and Groove bullets, and introduced their triple shock design.if you have a premium grade,hand lapped type barrel,they will probably shoot well.i tried some in my 700 rem and they shot terrible.the owner worked with me and was very nice.after a couple of months he refunded my money.as far as nothing will touch them,i assume you're talking about B.C., you might want to try some wildcat bullets.most would consider them to be the A,T and T of long range hunting.
