these projectiles are roberts 151 grain and a 150 flat nose 3030 . Both subs out of a 308. Cast bullet was stuck under skin of a hind on a lung shot and the other was stopped against the skin on a neck shot . Both were on hinds. I have used the winchester factory subs in 308 and found the projectile very fragile and wont use them any more.151 lead subs were the best. Most go right through. Have just loaded some 190 hornady sub projectiles and the most accurate load was 12,5 grains trailboss. 3 shots touching at 50 metres out of a begara takedown. Dropped 100 mm at 100 metres. Not subsonic but not too noisy, i went for the most accurate load. At sub velocities it shot abouut 35mm groups.
