1000 Yard World Record 4.2" for ten shots with a 6mm BR, Hornady 105 A-MAX bullets. The nut behind the trigger (Kyle Brown) worked well that day.

For terrific long-range performance with match bullets (220 & 240 gr Sierra MK at about 3000 fps), the 30-378 Wby is hard to beat. Also, the 338 Lapua with the 300 gr Sierra MK at 2750 fps works well.

Using hunting bullets in these two, you can expect almost 1700 fps remaining at 1000 yards with the 200 gr Sierra SBT, and over 1500 fps with the 250 gr Sierra SBT.

Hunting-weight rifles chambered for these cartridges may be built. The Barrett M99 weighs 25 lbs, before the scope is installed.

The M99 in 416 Barrett has the most speed and bullets with the best BC. It all depends on what you need (want). The article in "Shooting Times" reports on a most impressive rifle and cartridge. It should be tons of fun.
