Trail Boss load results strangeness ...

[GBExpat]

With the 100gr bullets I found the Velocity (and, thank goodness, also an Accuracy) Sweet Spot to be ~87% of Max.

Later this week when the drain field dries out I will test this with a 115gr String.

This last series, I tried a String of 115s loaded at the Max (4.0gr) and they produced an average velocity of 665fps.

I will load a String with 3.5gr (87% of 4.0gr) and see how it performs.

If my theory is correct, I will see an average velocity from this new 115s String in the upper 700s.

I will update this thread after I get that done.

Looks like I may be onto something ... two different 3.5gr TrailBoss 115gr Strings (only difference was seating depth) produced average velocities of 783 & 788.

With the 100gr bullet loads the .2gr separation Strings produced lower speeds on both "shoulders" of the High.

3.8..4.0..4.2
841 860 832

This new series shows the same pattern

3.3..3.5..3.7
764 788 775

So, it appears that, with these .32-20 loads at least, ~87% of the determined Max will produce the most velocity.

Interesting, so I should have worked up like I am supposed to.

87%. Gotta try it.
