I have a 16" .458 Recon Tactical billet upper that will be mated to my billet Super Sniper for hog hunting. Using the Wilson 300 gr Barnes TTSX rounds, could you tell me about where the round will be at 100 yards if I zero at 25 yards? In wanting a 100 yard zero, but only have quick access to a 25 yard range. Obviously actually zeroing at 100 would be best, but I'm just looking to get as close as I can right now.
