SPinsail. mattsbullets has some inexpensive offerings The Ray Thompson design in 265gr is a good one for the 44 mag. He has some Keith designs also. For the 45 Montana and Leadhead are good. Look for the Lyman in 44 cal and try the 429215 (I think Montana has some ) they are accurate. I load 2400 under them. I have had them drop from 215 to 230gr do weigh them If you ever do experience leading, then get a copper Chore Boy cut off a few strands wrap them around a old brush and it will take it out quick. Bad man bullets and Missouri sell the Hy-Tek coated no leading no smoke. But I have not found any that I would want for hunting . Don?t forget the Lyman 310gr with 21.5grs of H110 or 296another accurate load for 44 mag
