[QUOTE="gunsmith, post: 743672, member: 53434"] Another thanks to 41Mag, nice post! And to dbrow, Yes. The .25-'06 is a necked down 30-'06, which can put decent groups out to 1150 or 1200 yards before it runs out of stability, so the "magic" 1,000 meter group can be done. The bullet doesn't know how far its going...it just hits with whatever energy is left when it gets there. The .25-'06 can be made to shoot as heavy a bullet as the .30, but you will likely need heavier-than-lead slugs to do it. I have made slugs out of Tantalum in the past (machining them is a Royal PITA), their density is very nearly equal to gold (19.3 grams per cubic centimeter, whereas lead is around 11.3 grams per cubic centimeter). I made long ogive, semi-Spitzer/ semi-wadcutter boat-tail points specifically for 1,000 meter target work in wind. They are heavier, go slower, and therefore drop a bit more than lead/copper slugs, but they sure drift consistently in the wind. I shot these out of a 7mm Ackley Improved Remmington Magnum (which is not too dissimilar to a .25-'06). I was quite happy with the results, but it was years ago, and I don't have the data anymore. There are other materials heavier than lead as well, and possibly easier to machine. Still, I wouldn't hesitate to try it on a .25-'06, as you may indeed get a fantastic result at 1,000 meters with them. By the way, size the diameter to the lands, not the rifling grooves. Tantalum is hard stuff and will ruin a barrel quickly if sized to interference fit. You're shooting a cutting tool down that barrell. If you can jacket them with something softer (copper), that would be a good idea. [/QUOTE]
