I’ve had plenty of experience with the 300 blackout subs shooting 200+ deer and 1000+ goats. My main deer hunting hand loads are Lehigh 168gr CF and 194gr ME. Once you do all your homework on the Ballistics and practice on longer range angle shots it a easy caliber to use if your skills can match the rifle, ammo performance. Farthest sub head shots 245m and 251m in three seconds using a semi custom Tikka T3 12” barrel. Shot placement is critical or follow up shots required for runners and bad shots before the animal disappears. I mainly stalk the deer shooting free hand or snipe them off in the prone position at longer range. Shot three deer in the last three weeks. I’ve only lost two deer from bad shot placement my fault. The biggest stag I have shot with subs is 450 lb. For goat culling am using 208gr ELD subs and 125gr SST supers.
The scope is a Nightforce NXS 2.5-10x42 MOAR zerostop, the supers are zeroed in at 60m zero stop 9 MOA high on the scope turret.
Subs is zeroed in at 60m because that is the average shot distance and on the turret dail it matches zero, so it’s just a matter of ranging, dialing and shooting, a real easy process and the best of both worlds shooting subsonics and supersonics.
Here’s a red stag I shot two days ago from 18m away with the Lehigh 168gr CF.
