AFRO I have a 35.303 No1 Mk3. I shoot the same CBE 358250 Proj and have settled on 38 grains of 2206H. I do not use a Filler. I have a 22" Barrel and have chronied that load at 1885 fps. I had a 3fps variation across 5 shoots and cuts 5 shot 1 hole groups so will not be changing it either. I was using 38 gr of 2208 but the 2206H shoots a little tighter groups. In my Rifle the Lyman 358315 Proj over 36 gr of 2206H shoots quite well also, no Filler, no chrony. Zero leading, I use White Label 2700 lube
