Boggy, I am about to cast a supply of next summer's bullets. I use a Lyman #287308 168 grain in my 7x57 Mauser If you can wait until I get some made (probably this month) I cna send you a sample. You can E-mail me at scrumbled
aol.com I use a Lyman recommened maximum load of eighteen grains Alliant 2400 for 1850fps in a 29" barrel. Hope this helps, curmudgeon
