I have some questions as I am getting a handle on the Grendel quickly I hope. As the title states I am going through a divorce and the B&^% decided that she needed half of my Premier 5-25 and half of my 4,000 match rifle! It was harder to watch the damn scope leave than the wife haha.
So my plan is to keep shooting PRS/Tactical matches at a reduced cost with an existing match built AR 15 lower and swap the barrel on the upper to Grendel. I have some questions about the round
1. Everyone tells me the ballistics are the exact same as a 308. True or False
2. Can you achieve better ballistics by pushing a lighter bullet faster at magazine length?
3. Any recommendations for loads with a 1-9 twist Black Hole Weaponary barrel?
4. Is this a viable option in regards to trying to stay cheap and still some what competitive?
5. Reviews state that the 123 sst and 123 amax shoot the exact same. True or False.
6. Really looking at the berger 130 AR hybrid but would like a lighter bullet to increase velocity if possible.
Thanks for you help!
You will not be competitive with a Grendel match rifle in NRA High Power. You will not get any bullet going fast enough to match cartridges like the 6 XC, various 6mm gas gun cartridges, or even the various 6.5 cartridges like the Creedmoor. The disadvantage is pretty distinct at 600 yards.
If you want a Match Rifle for High Power using a AR-15 frame, look at the 6mm AR or 6 Turbo. Both are Grendel cases necked down to 6mm. Use a 105 Berger or 107 Sierra and you will be competitive.
However, if you want a decent hunting cartridge for an AR-15 frame, a 6.5 Grendel will probably be a better choice than one of the 6mm Grendel cartridge hybrids.
If you want to loose by fewer points in a High Power match, I think you would be better off finding a very good shooting load with the 108 Lapua or one of the 105 - 107 grain 6.5 bullets shot as fast as safely possible. I bet you would score higher than the 120 plus weight bullets out of a Grendel case.
