Here is the data I worked up for Clays with
230 LRN.

Gn Primer Avg Vel Sd
4.0 WLP 798 19

4.4 WLP 851 12

4.7 WLP 907 6

This was in R-P brass. Bullets were seated at 1.240". Best accuracy average between my guns was with 4.4gn. 2.5" in my Llama and 3.0" in my Norinco at 25 yards. It also put the group right over the semi-fixed sights of the Llama. as you can see the standard deviations are very low for this powder. Clays meters very well in my Redding and Lee measures I use.
