Was trying some ladder loads with my sporterised '17 Enfield. Tried some 168 Sierra Match Kings with Vihtavouri N 150. What a disaster. It shot patterns of 3 ~ 4". Then tried some SMK 155 Palma bullets with good ole, IMR 4895 got nice groups of about 7/8". Then tried some 168 SMKs with venerable IMR 4895 & got 8 rds into 5/8". (all groups C-C) (45.5 gr) This rifle was made in 1917 and re barrelled in about 1938 +/- with a US GI High Standard barrel. It has been thoroughly sporterised, free floated, Pillar & Epoxy bedded all by hand. Old type powder, old rifle and an elderly shooter. Never expected it to shoot so well. Lucky this time I guess.
