jacketed bullets over BP

[KWK]

I've read that during the transition to smokeless powder and jacketed bullets, some rifle cartridges were loaded with jacketed bullets over black, eg. the .25-36 Marlin.

Has anyone here experimented with this combination? Any precautions or "gotchas"? Does one dispense with lube wads, etc? Do hard jacketed bullets mashing down BP fouling create an unholy mess in the grooves?

I can't say I have any need to shoot such cartridges, but curiosity leads me to ask what they were up to 100 years ago.

It doesn't work worth a damn. Fouls out in a few shots and you'll be scrubbing the bore all day.

Where did they put the lube?

If this is true, it sounds like it was an experiment without lube with both types of powder. Obviously not viable with BP, but maybe the thought was to test them with both powders and see the results. One would think they would have had doubts from the beginning, but tried it just to confirm the short commings. again, I've never read anything on that scenario, but it is possible.

The early 303 Brit was loaded that way for a year or two before Cordite was fully developed.  Don't know how well it worked, but the rifles were ready before the proper powder.

From somewhere in my hazy history I seem to remember that the English Spitfire fighter had .303s.  I wonder if they might not have been named Smokefires if that ammo had stayed with Holy Black. . .

D.D., the Spitfire had eight Browning .50 cals, four in each wing.

FCK,   
      Actually the vast majority of Spitfires flown in WWII had from 4-8  .303 machineguns ,wing mounted (MK I-VIII. PR.X, MKXX). The only ones documented as having .50 cal guns were the MK IX with 2 each and the F.XIV w/2 .50 cal and 2/20mm cannon. The F.21 had 4 ea. 20mm cannon.  You are correct about one thing, all their MGs were Brownings.

Note: The Mks were primarily pursuit and fighter aircraft. The P models were reconnosance/photography and the F models were mostly experimental towards the end of the War and immediately afterwards.

I stand corrected, thank you sir.

I have not yet tested anything serously but I do have some 44-40s loaded with Pyro-P and Speer JHPs I can give rats behind how dirty or clean they get as long as my first or second shots hits my target! I have them for self defense. More than likely a RNFP is good enough....they were back in the day right?

So far all I have done is chronograph them

[Bryan Austin]

Oh one other thing....it is very hard to keep the bullet straight when setting it. Jacketed likes to get sideways more than lead for some reason.
