Here is a post from someone on another forum who seems to have the info you need.
"Several weeks ago I order 500, 30 caliber M-160 frangible bullets for $28 pulled from de-milled US ammo, thinking this is a great deal if they shoot good in my 30-06 & 308's. After researching this bullet, It was designed for M-60 gunners to practice shooting at flying drones and moving APC's. It weights 108 grs and is made from compressed lead dust and epoxy with a resine coating and yes they are old and ugly looking, but with no pull marks. Intended velocity is 1300-1400 FPS. Using conservative cast bullet data and 30 cal 100 grain Speer Plinker data, I started with 8 grains of Unique in my 30-06 and worked my way up to 11 grains. 9.5 grains of Unique was the sweet spot for my 03 springfields, average velocity was 1318 fps @ 10'. Group size was identicle to my favorite cast bullet load (2" with 5 shots at 50 yds with open sights). Be very careful you do not double charge the casing!!!!! Recoil and report is like a 22 mag. Here are a couple of tips: Use a Lee universal case mouth expander die to put a slight flair on the case mouth to prevent the bullet from shaving during seating. Use Lee factory crimp die as your final step. Do not exceed 1400 fps. This is a low presure, low recoil 100 yard load you can make for under a 8 cents. Case life will more than double, and use a Lee collet neck size die and you can go 8-10 firings before needing to trim the brass. No noticable bore fowling. I just placed and order for 2K more. You may want to use a progressive press, because once the kids find out how much fun these are to shoot, you will need to load them faster and faster."
