Winchester match bullets
If they are in the original box you may want to consider holding on to them instead of shooting them. Their worth as a collectible may be more. Don Gentner makes an excellent match bullet that will serve your purposes well and so do others. You would kick yourself in the butt if you found, five years down the road, these bullets are highly prized by collectors. Just something to consider. A buddy of mine has some of these very bullets and commented on them being very accurate. He doesn't shoot his remaining stock for the reasons just mentioned.
