Not so good range day

[Hylander]

So took my new to me T/C Hawken out.
Load was:
.490 RB, 60gr. 777FFF, CCI Mag. cap
.018 Pillow ticking, olive oil.
Also used .020 Drill material.
At 25yds the shots were bout 1" apart, thats ok, so I move to 50yds.
Things opened up bad, say two almost touching and a couple 4" away.
Patches are not burnt or torn, they are good enough to reuse, if need be.
Things did tighten up to about 2" with a .495 ball, but it is hard loading.
I am thinking I need to revisit my old load data from my first T/C Hawken which always shot under 1.5"
I am thinking since the grooves are shallow on the T/C, maybe a .495 ball with a .015 patch

that 015 patch should do the trick. Did you try cleaning between shots?

Try more powder.

 

[Hylander]

Yes, tried swabbing.
Will look for some Ticking in .015
Will up powder charge to 70 and 80 gr.
