A 24gr charge of Win 748/Win brass/123 gr bullets shoot nice out my son's SKS.Ballistic tips are soft enough to expand reliably as well.22gr RE7 gave 2000fps with 150gr bullets as did 22gr of IMR 4198[150 gr]for 2100fps with good accuracy...........Harold PS get the Hornady dies as they come with a .308 expander and a .310 as well
