Howdy!

I admit it, I am stumped.

We went down the farm yesterday for some plinking. I took the M1860 Colt Army R & M in .44 Colt and several boxes of factory "cowboy loads" (aka smokeless equivalents), and my M1875 Remington in .45 Colt and a couple of boxes of blackpowder cartridges we loaded.

Using a fancy Dylan (650?)... the BP's were filled to within an eighth of an inch, and All cartridges were visually inspected for powder drop and volume. The bullets were seated with gentle pressure feeling the powder "give way" a bit. Just a bit, no force, no pressure. Just slightly firm.

Targets were a case of old cans of my late mother-in-law's "Natural Lite" (Natty Lite) cheapo beer (smells like diluted horse pee) shaken up and set on a hale bale at 75 yards and then 75 feet.

First box of 50 went normally BP fine.

I broke out the second box. made at the same time.
Loaded. Stepped up.

BLAM! Sounded and felt like a "44 Magnum." Rang my ears even wearing foam ear plugs. May be 3-4 times

A double load i thought at the moment. (I know, not possible but I was just shooting smokeless in the .44.)

Cocked, fired.

BLAM! Sounded and felt like a 44 Magnum. Rang my ears even wearing foam ear plugs.

And so on teh exact same for a run of 18. (Shots, not beer cans. ;) )

I cannot explain it.

Answers? Ideas? Theories??

Dunno Mick.....sounds like they were loaded right. I don't know the effect a magnum primer might have on BP.....too tight a crimp ??...........double check your powder granulation size.....all that comes to mind.

Foaling in the bore creating extra resistance?.........don't know if that's even a "thing", but if everything else is the same....that's all I could come up with!

Thanks, pards.

"It" defies logic.

Every "variable" was covered as the same. The only different was that the finished cartridges went into a second plastic tub/holder when teh first 50 filled the first one.

Yes, I was thinking that the heavy fouling might be to blame decreasing the bore size for the same size bullets. BUT, I got hot loads starting with the first round AFTER the gun was cleaned. (The cylinder was getting "stiff' after about 15 rounds, and had to be manually turned if I went 24. Better than the Italian Schofield's with the deleted gas checks- they got stiff at 44-5 and had to be turned by hand for the 6th round. ;) )

Black powder cartridges like a little powder compression..... but it doesn't sound like you overdid it.
What kind of powder were you using ?
