Need Load Data For 150gr Masterblasters In 38 Special

I have used Titegroup with good results for 158 gr MG CMJ bullets.

For a 150 gr bullet, I'd probably start at 4.0 and work up. Load about 20 each of 4.0 , 4.2, 4.4 & 4.6. Shoot them for group over a chronograph and may the best load win!

4.0gr of Titegroup makes power factor out of my M19 with this bullet.

It averaged 861fps

ES: 68

SD: 24

129150 power factor.

The recoil impulse was a little too snappy,IMO.

I'm going to experiment a little more with pushing the Clays up before I settle on the titegroup

With 3.0gr of Clays,i got an average of 700fps

With 3.5gr of clays i got an average of 800fps

I'm going up to 3.9 and 4.1 with the Clays and if that is pushing too hard,I'll go back to the Titegroup.
