200 grain Saeco cast, 21 grains AA1680. Remington 7 1/2 primer. 1350fps out of DW 10"
210 grain RCBS 35 Rem bullet, 20 grains AA1680, WSR primer, 1200 fps out of 10" T/C barrel. (mild silhouette load).
Both loads are sub MOA.
DO NOT exchange primers with this powder without working up. Huge pressure difference. A friend of mine was 23+ grains of AA1680 trying to duplicate my DW load. He was using WSR primers. He switched to the REM primer without backing off the load. Brass was pretty well stuck in the cylinder for a while.
Good luck and stay safe.
