sierra .223 blitz in a 1-9 twist

[buddy.223]

I have a cz 527 varmint that shoots 40 - 60g ballistic tips very accurately, the 50 s particulary well (literally ragged 5 shot groups) 25g n133, 25.5 benchmark 27.5 blc + a couple of others, iwas given a couple of boxes of the blitz (1340) not the blitz kings to try & could not get them to group well at all 11/2+" , could someone recommend a powder, charge to suit or is the 1-9 a bit fast for the round

We run the 53gr Sierra in T3 8 twist with 26gr BM2.Extremely accurate.BM2 meters exceptionally well.

i get great results with the 52 & 53 smks also , just cant get these lead tipped suckers to shoot, pity as i can lay my hands on some cheap.
