Agreed. All data I used was from previous forum data, with no pressure numbers. Just what had worked for the owner. I've been at the 18gr mark with no filler, and it was very dirty. Other factors for the 38wcf were why I tried psb. I started at 17grs - 6.5psb, stopped at 17.5 - 6.
On another note, 23.5grs of IMR 4227, 200 gr Speer, Win std/mag primer, was quite clean. BUT in a Remington model 14 1/2 rifle. This,Savvy Jack is the load I'd shared with you by phone message a year or so ago.
I would NOT use in anything but a STRONG rifle.
