I'm thinking of using this from my 12" for whitetail this fall. Even at 350' ASL I should still be able to get a decent range as long as I do my part with proper holdovers.
ETA: playing with a couple ballistic calculators, my MPBR would be about 240 yds. This would still have plenty of speed at ~1700+/- but energy is now a bit under 900 ft lbs. Enough?
I haven't used his 129 ablr on game but I have used his 127 LRX load on game.
His 129 ablr load should be gtg. And yes 900 ft lbs is more then enough for deer.
I kill them with stick and string and that doest even make 100 ft lbs.
Put the bullet through the heart it dies, put it in the high shoulder/spine it dies on the spot.
