30-06 rifles, and muzzle velocities
are almost always very close to 2,900 fps in 24" barrels.
My intent was to check to see how actual muzzle velocities
compared between the two cartridges.
Instead of using 180- or 200-grain bullets at the muzzle velocities
possible with 158-grain bullets in the .
But C&C bullets don't have to be limited to modest muzzle velocities
Instead most loading manuals list top Swift 40-grain muzzle velocities
of around 4,200 to 4,300 tips.
0 grains of Unique or WW231 gives muzzle velocities
in the 925 to 950 fps range.
They're the finest rifled shotgun slugs we've ever had plus muzzle velocities
keep increasing with every passing year.
With these loads and bullet choices, muzzle velocities
are in the mid-1,400s to high 1,500s.
Switching to the Encore, as expected, the muzzle velocities
were significantly higher and, in the same order, came in at 2,589 fps, 2,091 fps, 1,987 fps, and 1,787 fps.
Both gave identical muzzle velocities
of 1,600 fps and three-shot, 50-yard groups of 1/2" and 3/8" respectively: while 11 grains of H110 tipped the muzzle velocity to 1,765 fps and a one bole--very small one hole--1/4" group.
or heavier bullets, especially those with gas checks at muzzle velocities
above the standard 1,300 fps black powder level load.
Using a 7 1/2-inch barrelled Colt SAA and shooting over Oehler's Model 35P chronograph resulted in muzzle velocities
of over 1,000 fps.
