You can get custom turrets also. In any formats- mils, moas, yardages...
It is best to take the gun with the particular load and get the true bullet drop path before sending that data in to get a custom turret set-up in yards.
-Check out the "kenton industry" website to save explanation on what a custom turret is capable of on certain scopes.
For max range hunting, some bullet path calculations include velocity at all ranges along with the drop of the bullet. A good rule of thumb is 2000fps for minimum impact velocity depending on the bullet to get good expansion. A bullet that doesn't open up results in wounded animal likely to get away. So those hard military bullets aint gonna work for hunting game, they really are for military applications only like piercing heavy armors and killing people.
All bullets and caliber combo are different for minimum impact velocity. I shoot berger vlds because it has high bc, out-pentrates all other hunting bullets I know of and has a violent expansion after pentrating about 2-3" in to an animal. The 7mm 168vld @ 3050fps pentrates 3/8" steel at 500 yards and the recommended minimum impact velocity is about 1800fps so this load easily keeps that speed beyond 1000 yards. Excellent for deer and elk.
Those accubonds are cleaner (not such a violent expansion) and has a lower bc so it is slower than the vlds at extended ranges. Yet those accubonds can still go over 1000 yards with the right load and gun for big game hunting. Accubond, hornady, berger, lapua, sierra, and on... they all will easily take big game out over 500 yard with hunting bullets. Some target bullets are not consistent on big game due to inadequate pentration.
Here ya go! Some turret and bullet info- you got a broad topic!
