Re: Grendel Distance?
The 123 grain Scenar load at 2550 FPS doesn't go transonic until around 1300-1400 yards. How far someone could hit a 6 inch disc would depend on so many factors I would hesitate to put out a guess. I'm not trying to be a smart ass, but here are some of the factors that would effect hitting the disc:
1. How well can the person shoot?
2. How accurate is the rifle?
3. How accurate is the ammo (consistent)?
4. How windy is it, and how well does the shooter read the wind?
5. What are the meteorological and environmental factors that would affect
how far the bullet travels before going transonic?
6. What kind of scope is being used? A 2x scope won't help much at 850
meters, while a 25X scope would be much better. Also, the quality of the
optics and system make a difference.
7. Will the rifle be shot from bench rest type position, or field type position?
Like any cartridge, the Grendel has it's benefits and problems. Although it is still supersonic at 1000 yards, the 123 grain bullet doesn't have as much energy as a 260 Remington. I'm a real fan of the Grendel cartridge and absoutely love it for practical rifle matches. It travels better and farther than a 5.56, but lacks the recoil of the 7.62x51. My Grendel has about 10-20% more recoil than the 5.56 (not much, barely noticeable), but seems to hit steel plates with about 80% the energy of a 7.62x51. So it is a great compromise. And for bucking wind, the 123 Scenar bullet is far better than either the 5.56x45 or the 7.62x51.
The amount of elevation adjustment either cartridge requires isn't an issue, because once I have to start adjusting, there isn't much more effort to adjust either 4 moa or 5.5 moa.
For whatever it is worth, my Grendel usually shoots .6-.75 moa. I get a number of .5 moa groups, but I get alot more in the .6-.75 range.
