The cartridge can be extremely accurate to 300 yards (270 m) and beyond, but may not retain enough terminal energy to reliably drop medium game at that distance. [ 4 ] [ 11 ] [ 12 ] Highly experienced hunters use the .243 Winchester to routinely drop bucks up to 250 pounds (110 kg), [ 2 ] while less experienced hunters can be just as capable ...
The 243 Winchester Super Short Magnum or 243 WSSM is a rifle cartridge introduced in 2003. It uses a .300 WSM ( Winchester Short Magnum ) case shortened and necked down to accept a .243in/6mm diameter bullet, and is a high velocity round based on ballistics design philosophies that are intended to produce a high level of efficiency.

The 6.5-284 has been used extensively in benchrest competitions and is known as an extremely accurate long range round. Using an improved version of the 6.5-284, Rich DeSimone set a 1,000-yard (914.4 m) world record with a 1.564-inch (39.73 mm) group. [4]
Finally, there was the added benefit of increased range, as the torpedo traveled a significant distance in the air before entering the water (up to 1,000 yards (910 m) when released at 800 feet (240 m) and 300 mph (480 km/h)). Combined with radar that delivered the exact range to the target, the results proved to be remarkable: [11]
At 2,400 m (2,625 yd) the total drop predictions deviate 47.5 cm (19.7 in) or 0.20 mil (0.68 moa) at 50° latitude and up to 2,700 m (2,953 yd) the total drop predictions are within 0.30 mil (1 moa) at 50° latitude. The 2016 Lapua Ballistics 6 DoF App version predictions were even closer to the Doppler radar test predictions.
The trucks were carrying about 25,000 liters of pesticides and 76 tons of sulfuric acid, according to the National Agency for Water and Basic Sanitation, raising concerns about environmental damage.
On impacting the water the torpedo either runs out for 1,000 yards (910 m) or performs a dive at a 30-degree angle to the search depth. After completing this it may perform a flat turn and begins a helical search pattern proceeding up or down until it hits either the minimum depth of 50 yards (46 m) or the search floor.
A solo hiker bounced from rocks as he fell 100 feet from a cliff into an icy lake in Washington, deputies said. The injured man sent an SOS signal Sunday, Dec. 8, from Lake Serene, the Snohomish ...
