Hei.
Må regne slugs i hagle som kulevåpen med "stor rekkevidde" ca 4000m.
Her står litt om rekkevidde og gjennomslagskraft på 500 grains kuler i kaliber 45 i ca 390m pr sek
Testet opp til 3500 yards.

The report of November 13, 1879, lists the results of firing tests made at 3,500 yards distance with two long range Springfields. One had a rifle barrel with a l-in-18 rifling twist, the other .45-80-500 had a 19 5/8-inch twist. Two different loads were used: .45-70-500, and .45-80-500. The Martini-Henry .45-85-480 and the service .45-70-405 Springfields were again tested against a Sharps-Borchardt using the same loads as in the long range M-1873 Allin-Springfields. After firing many rounds, the service Springfield and Martini-Henry rounds failed to reach the target at 3,500 yards.
In these firing experiments, two telephones provided with Blake transmitters were used for timing the bullet's flight. One was placed within a few feet of the rifle, to receive and transmit the sound of the shot. The other Blake unit was nearly two miles downrange in the shelterproof, which was located about 30 feet in front of the right edge of the target. At the instant the sound of the discharge was heard over the telephone, a watch ticking fourth-seconds was started. At the sound of the bullet striking target or sand, it was stopped. Average time of flight for the .45-70-500-grain load was 21.2 seconds, with the more powerful .45-80-500-grain cartridge the time-of-flight was 20.8 seconds.
For 3,500 yards distance, angles of elevation ran from 27 degrees to 29 degrees. This varied drastically from day to day due to the effects of head and tail winds. The quicker-twist rifles required less elevation than the others at the same range. The greatest distance obtained with the .45-caliber long range, 1-in-18 twist Springfield rifle was 3,680 yards. Angle of elevation didn't exceed 32 degrees on a day when an angle of about 25 degrees placed bullets all around the target at 3,500 yards range.
