[QUOTE="budlight, post: 2502246, member: 2939"] single shot and bolt guns are not limited by mag length just the free bore to the lands. If you really look into ballistic charts and use real world chronograph data of your rounds out of your gun and max accuracy is usually achieved at something less than max loaded short case life rounds. Then you plug in all the BC and data and I came to the conclusion that the heaviest bullets per caliber were not always the best because a small volume case just can't push them fast enough. The starting velocity is so low that they become more like artillery with the bullet drop. The heavies with higher BC only have a foot pound advantage way out there. The case volume of a 223 is tiny compared to my 26 inch 22-250 where a 90 gr actually makes sense [/QUOTE]
