|Clays (Grains)||Avg Vel||StdDev||Notes|
|3.0||639||43||S93. Never ejected or cycled the slide, but always fully cocked the hammer. Worth investigating with an ultralight action-spring|
|3.5||738||28 (9x)||S94. Mostly cycled, some failure to lock back slide with firm hold.|
|4.0||833||16.23 (10x)||S95. Cycled slide, but failed to lock-back on empty when limp-wresting.|
|4.5||914||11.2 (10x)||S96. Starting to have well-cut holes in paper, but still not totally crisp.|
From the table above, Velocity (fps) ≈ 91 + 184*grains_of_clays.
