I have a Turkish converted G88/05/35 that I'll be loading for. I want to keep pressure on the reasonable side, because this rifle is VERY old. I'll be using Lyman 314299 3% tin 97% lead that drop at .314" wrapped with two wraps of copy paper up to .323", and 180 grain J-bullets.
I have Unique, Trailboss, IMR4895, AA5744, WC-872, and a variety of other powders available to me.
Any suggestions? What have you folks had good success with? Here's a photo of the rifle.
