I have two very accurate loads in my M70 Featherweight pushfeed and my M70 SG Featherweight crf using the wonderful 139gr Hornady Interlock flatbase. 44gr of IMR 4320 or 49gr of IMR 4350. Coin toss as to which one is more accurate on any given day. Don't know the velocities but guessing somewhere around 2775 - 2800 fps.
