Remy,

Nick Sisley ran an article some time in Skeet Shooting using rst-cheddite with now defunct PB, 7625, and both Universal and International by Hogdons in DR 16 hulls, and BP 16 hull in 3/4 and 7/8. Very easy on the shoulder in 3/4. Someone also used 20/28 in the dr hull 3/4 with 15 grains, and had it tested by Precision. 1150 fps and 5000 psi if memory serves me well. i think these were posted on the Parker site some time ago.

good loading
