It's a ok load mild but no power behind it! next time I'l try 8gr.
7.5 Unique / 240 in the .44 Spl is the old standard Skeeter Skelton load.
It will get awful close to 1,000 FPS in a longer barrel.
And I can GayRonTee ya it will shoot through several 2"x2"'s stacked prison lover style.
I wouldn't have thought the greater case capacity of the .44 Mag would slow it down that much.
now THERE'S a name you don't here every day.. and used to..
I've chronied 7.5 grains of power pistol in magnum cases from my 4" SW model 29 with 240 MBC brinell 18 at 800fps. The unique load should be close to that.
One other possible explanation would be your powder measure "bridged" a load of unique, giving you less than a full 7.5 grains. FWIW metering issues are why I got away from unique. I liked it as a powder, but my chrony results were crazy bad with extreme spreads of 100 fps or more.
Impossible IMHO, assuming there was 7.5 Grs of Unique in the case, and it was anywhere near the primer.
It was near enough to the primer to shoot a 240 SWC through a 2" board at 10 yards!!
That right there is what I have been thinking all along!
steel plate (hit low) they do all kinds of damage to the 2X4.
Lee 240 gr. SWC pushed by 10.7 grs. unique, tumble lubed, Alox two coats, no leading.
10.0gr should reach 1200fps in a 7½" barrel!
That I don't know. Lyman uses a 4" barrel for their data. I don't see anywhere what barrel length we are actually talking about here.
But regardless of that, 7.5 grains Unique/240 SWC in my 4 1/2" S&W .44 Spl will give a 2"x2" board all it can stand and then some!
I would think that even in a mag casing it would easily go through a 2x4. Is there a chance you could have had a light load? Somehow didn't get all the powder in that one?
the barrel leanth is 5.5 on my SBH
In about everything that will go bang.
And I'm here to tell you it don't need toilet paper stuffing to get it to light off in anything.
I'd be looking at your reloading equipment, and your load safety checks after dropping powder.
If it bridged in your powder measure and only dropped a partial charge, say 4.0?
Not enough stuff to shoot through a 2" board perhaps.
If the extra 3.5 grains of powder got in the next case, I doubt you would notice it in a Super Blackhawk.
7.5 + 3.5 is still 2.0 under max with a 240 Keith SWC in a .44 Mag.
I'd use loading blocks, charge 50 cases at a time, and look at all of them to compare powder charges before seating bullets.
Except for a rare handful of guns that shipped with flat-top barrels, Supers were never offered as 6½". They've been catalogued in 4 5/8", 5½", 7½" and 10½" lengths for quite a few years. Although 7½" is surely the most common.
