Y'all know her. 24 inch, stainless/ walnut .50 caliber, aperture sight.
I have a number of loads, all use 70 grains of 3f Swiss. The 230 grain XTP uses a regular Harvester smooth sabot. The 250 and 300s require crush ribs.
Big lead is the Lyman 400 grain Plains, lubed with SPG and a .54 lubed Ox Yoke wad. There's also the 370 grain Lyman Maxi, same lube, bottom groove only and same wad.
Velocities as follows:
230 grain- 1630 fps
250 grain- 1575 fps
300 grain- 1500 fps
Lyman 400 grain- 1350 fps
Lyman 370 grain- Not yet chrono'd, but I suspect about 1400 fps.
Here's the kicker though. Zeroed to have the 300 grain XTP hit point of aim at 100, the 230's are + 3", the 250s + 2", the Lyman 400s -1" and the Lyman 370s- dead nuts.
So. Out to 100 yards, 5 different loads can be used with ZERO necessary sight changes!
I have done no bedding work on this one. The barrel came fully floated.
To me, this borders on miraculous.
Such a GOOD girl...
Calico and the " doe loaf". That one fell to the 300 grain XTP. 85 yard shot. Didn't feel like wasting the round after bear season, sooo...
She was 125 lbs dressed. On scales, no guesses.
