Flask problem

Post by Niner » Thu Jul 07, 2011 11:36 am

The best laid plans....you know how that goes. And the spur of the moment plans work out about the same in my case.

I took a notion to see how my bp 1853 Enfield would shoot some new ammo along with using some new musket caps. I got one of my flasks and proceeded to load it up with some Pyrodex to give me extra powder since my actual BP supply was gone other than a little I had in my regular rifle flask. Then...after loading the spare flask up, I discovered the spring catch wasn't returning the brass shutoff. Had to take it apart and seeing the brass piece that seals the opening had come loose I had to figure out a way to get it on with some likelyhood of staying on. Best solution I could come up with at the moment was to use a little super glue. Have no idea how long this will fix it.

The shooting secession was scrubbed as it would be pretty warm by the time I got to the range. Not much fun shooting in middle of the day 95 degree heat.

I have one flask which I leave in the Remington Pistol Box for show. I never use it to load the revolver. I pre-measure my loads into plastic tubes and charge the cylinder that way. It means consistent loads and safer loading (IMO).
I know we have already discussed the weight-v-volume thing Robert, however............................most recommended loads are quoted in grains (which I convert to grams) and load accordingly using scales.

I have noticed how corrosive BP is, even in flasks and so decided some time ago to use my plastic tubes. As a matter of interest, I get them from a local chemist who sells them to a lab for blood samples to be put in analysis - MUCH cheaper than those sold by gun shops :lol: :lol:

According to Sam Fadala....long time guru of US bp shooters.... what you are doing is not only not according to Hoyle but could be dangerous, particularly if you were using a bp substitute. The difference in actual weight against a volume measure can be of some significance. For instance, Pyrodex, measured at 88 grains by weight would be 120 by volume, and this could produce a safety issue in some guns.

BP has a more closer relationship.

Here are some numbers from Fadala's BP loading manual.

ffg Black powder:

40 grain setting by volume equals 40.3 by weight.

60 grain setting by volume equals 61.5.

80 grain setting by volume equals 81.2.



But if you use Pyrodex RS for rifles:

40 grain by volume equals 28. 0 grains by weight.

60 grains by volume equals 44.5 grains.

80 grains by volume equals 60.0 grains.


For pistols, using Pyrodex P

20 by volume is 14 by grains weight.

30 by volume is 24 grains weight.

40 by volume is 31 by weight.

Can't get BP substitutes here, only use Pure Charcoal Robert. :cool:

Doesn't answer my question though. If volume is so important, why do recommended loads come in Grains / Grams from the people who make BP replicas?
I would suggest that a variation of 1.2 grains makes little if no difference to a load of BP.

Here is a chart that is possibly..... kind of...sort of... about correct.

I mentioned the volume thing because somebody who doesn't know any better could use Pyrodex or some other subsitute by weight which could produce a problem. If you just use the volume measure all the time you don't have to worry about getting any measurement mixed up.
