I've cast and shot quite a few 311413s using pure lino, works quite well.

Can you get anymore velocity out of them, with accuracy?  I've shot a couple different models of the Squib bullet.  B&M311169 and Henesley's early version that had an extra band above the top lube groove.  Couldn't get either going much over 1600fps with any degree of accuracy.  The Henesley threw wider patterns as the velocity went up, though I thought it would do better than the B&M.  I recently got a newer version of the B&M, there's quite a difference in the bullets.  The newer one is more like the 311413, about .020" longer with a slightly different nose profile.
