The 600lbs gorilla

The 123 is .510 but overall length has a big influence on BC. Obviously the 107 is shorter, which is why the bc suffers. The 123L has a bc of .540.

Truly amazing, enjoyed the 1084 yards shooting.

I indeed have 4 of them but for long range work we use the 338 Edge or 408. The 47L is a fantastic round for 1760 or so in, not that it would be my first choice for any animal at distance due to energy. For competition 1250 yards and in the 47L is perfect. I am tempted to use the grendel at the SRM at Raton next weekend since all targets are 875 and in.

Wind, when read correctly, is not that evil or the 600 # gorilla. It just takes practice and rounds down range. For new shooters wind at max ord is the most effective way to eyeball wind without forgetting wind matters over the entire bullet flight path.

For the Grendel, I can not see the use of any other bullet than the 108 or 107 (although the bc for the 107 is horrible and excludes it). Find a load that the 108 and your gun like and run with it.

like I said before The 108 is nice but it falls subsonic at 1125 if 2950ftps is reached. The 123 a max launched at 2750 is supersonic to 1250 or so. The 108 may not be stable past the 1125. I guess my question should say whats better at extreme range for the grendel.


I do shoot to 1200 regularly and have room to a mile this is the reason for my question.

The problem is a bunch of problems grouped together. One is mean projectile speed. Normal assumptions is that it takes 100,000 to make it to any object with any type of consistency. That puts max effective at 1150 for the 108 and 1195 for the 123. The next one is that the 108 has a fairly vld ogive where the 123 has a more conventional ogive which moves more weight away from the bullet centerline, that normally would mean that it would not transition as consistently as the 108. We have seen 5 hits on a silhouette at 1450 with the 108's. The 123's are fantastic in a caliber able to push them fast enough to maintain the MPS above 100,000.

If it were my money (and it is), I only shoot the 108's due to above listed problems. I have not listed all the problems or solutions that the 108 encounters that the 123 does not accomplish. On top of all of them is the fact that the 108's are flatter shooting. The only thing that the 123 does better than the 108 is downrange energy.
