24" barrel. 80 deg. 65% humidity. Calm wind. Sea level.
Hornady 123 AMAX. Varget 28.4 g. 2473 FPS
Hornady 123 AMAX. AA 2520. 29.4 g. 2572 FPS.
First time out today with my Grendel beyond 300 yds. It was "nuts on" at 500 and 600 yds with both loads hitting the center of a 10" steel plate consistently. Very very pleased.
At 500 yds with the Varget load JBM called for 3.7 mils. Actual was 3.5 mils.
At 600 yds. " " " " " " " 5.1 mils. Actual was 5.0 mils.
At 600 yds with the AA 2520 load JBM called for 4.6 mils. Actual was 4.7 mils.
I did not shoot the Varget load at 600 yds as I only had about 25 rounds of each and I shot the Varget loads first. It is also a little on the slow side which is why I also did not try it at 1000 yds.
1000 yds. Different story!! BTW my past history for the last couple of years is shooting 175 SMK 308 WIN 2640 FPS at a 1000 yds with average results.
I only shot my AA2520 loads at 1000 yds and they were very inconsistent. I suspect they were becoming unstable hence my velocity was not high enough.
At 29.4 g of AA 2520 I am close to the book "max" so back to the drawing board even though Alexander Arms publish little higher numbers.
If someone could chime in with 1000 yds Grendel experience I'd appreciate it.
MINIMUM VELOCITY REQUIRED WITH THIS BULLET TO REACH 1000 yds??
I have only shot the 123 AMAX since getting my Grendel.
SHOULD I TRY A DIFFERENT BULLET. SMK OR LAPUA MAYBE??
I have enough AA 2520 to try and squeeze a bit more velocity out of it but also have 8 lbs of IMR 8208 that I have not even opened.
As I said before a real fun gun to shoot. Had a few guys ask me about it as they had not seen the round before.
