Went out today with the Black Diamond and some 300 grain ( non-mag) .45 Hornady XTP's and 90 grain( weighed) charges of Swiss 3f.I also started indexing the sabots.THANK YOU to whoever came up with that idea! Definately works for me. All groups were 3 shots at 100 yards. Group #1 - 1 1/16 inchs Group2 - 5/8 inch and Group 3 - 1 inch on the dot.Had 1 called flyer when a CCI musket cap disintegrated , even with that all 10 shot were grouped into 2 1/8 inches. Without the flyer 9 rounds in 1 7/16 with a horizontal dispersion of 5/8 inch :shock: .Fouling was a non-issue but recoil...Lets just say she INTRODUCED herself! She only weighs 7 lbs.
I checked out several sabots , Harvester Crush Ribs, and found a major difference between those shot with Triple 7 and black. The one's shot with black showed a significant flaring of the sabot base( skirt)compared to one's shot with Triple 7.This I did not expect as T7 produces higher pressures than black.However black has a sharper pressure curve so perhaps the sabots get an initially greater kick from the black and possibly seals the bore quicker toccasionally I get alittle fouling on the sides of the sabot with T7 but have found none , so far, with black.This is the heaviest powder charge I've ever dumped down a barrel.God bless and help you 150 grain shooters! :shock:I will chrono this load as soon as I can.My velocity goal is mid 1500's to mid 1600's as this bullet is rated to 1700.This will be my " If it bites, claws or gores " load.
Another happy surprise is that it is easier to swab the barrel clean between rounds with the black powder loads than it is with T7. The breech plug is another story though.The threaded portion of the plug, ahead of the nipple seat , REALLY gets a hard clinker in it.I use a 270 bore brush to scrub it out.I began applying bore butter to the recess of the plug and that threaded portion and the fouling comes out nice as you please!I'm going to get another plug and have that extra threaded portion smoothbored. This IS more fun than a human being should be allowed to have...
