P>Since I'm interested mostly in the upper end of the ballistic
spectrum, I next decided to test results on fewer charges but with
different sabots. If you haven't tried several brands yet you're
going to see exactly what I was referring to above about dimension differences
on sabots. The various sabot combinations I've shot to date vary significantly
in diameter, which may be realized in the difficulty/ease experienced during the
loading process. The tightest, largest diameter, I've encountered were
from Barnes which require a great deal of pressure to load. The 45 cal
black sabots I have on hand from Precision Rifle, vary fom .502 to .506, and
load quite easily. I also measured Hornady 44 cal (green) at .504 and Thompson
Center PTX sabots at .504. I don't have any of the Barnes left to measure but
they are definitely larger than .506 based on effort to load. The
measurements are probably not exact as I used a caliper which will dig into the
plastic to some degree, but should be representative for my purposes. The
diameters do vary and I want to explore the effect of the difference.
My favorite bullet/sabot combination to date comes from Precision
Rifle. They offer 3 different sabots for their bullets, so you can decide
which your particular rifle likes best. The results in mine are shown
below.
All tests used PR Extreme Plinkers in 300 gr for comparison.
