"nothing is impossible to the willing student"
I blew the nipple out of one of my post hole guns - shredded the metal on its way out - used a half charge so 6 inches of powder then rammed in six...

......

From the Goex MSDS spec sheet 3/17/2009

2070fps

so if that is the burn speed of black powder - once the projectile is escaping at that velocitythe powder burn speed cant make it go any faster...

There is a myth (in some places) that blackpowder cannot generate high pressure - there is enough shredded steel down the pages of history to explode that myth (literally) yet it persists in some...

We always used single cut measures for muzzleloaders mostly spare brass cases (cut down if needed)- I solder a loop of copper wire on the base and the measure stays tied to the possibles bag by a...

its an interesting question (for some) ....but getting the answer a pretty pointless excercise .....if all you know at the end is how fast it went but no ide where it went ?????? whats that gain???

believe that is correct

this !!!!! all of it !!!!!

They dont listen to me either :grin: but I figure I must need the typing practice. If you reckon its more likely a chain fire starts at the back - I proly agree

If you can find it, cotton japara is the best thin material, tight weave and tough, pocket material (like jeans pockets is purt near same thickness but not as strong) calico is next thicker, then...

HA!!! theres reasons we hang around here !!! -----waiting for little nuggets of wisdom to drop ------might be you just dropped one for me . I been using spacers (5 or 6 in the puck stack) made from...

most of us are happy with the idea that coarser grains = slower burning. The difference from Fg to FFFg, is noticeable
so if we made a compressed pellet from dampened meal, then we should expect...

why not go to a thinner patch?
if it blows out bad enough to reduce accuracy try an overpowder wad under the patched ball
I shot 120 grain loads in a 54 CVA for years - 530 ball on a calico patch...

replied to your other post on this

I bought a Chiappa standard grade - used (as new six shots fired) - discounted - brought it home - wouldnt cycle a round from the magazine - the rims were hanging up in the carrier - I got mad at the...

fertiliser store - go someplace where there is drip irrigated horticulture - greenhouse grade in 50pound bags

my take
You wont get what you want with an open system (percussion or flintlock)
so cartridge gun (has to be a wildcat along the lines of a 50 BMG case necked down to something 30's clibre)
OR a...

last sentence ........................

well ? might be able to do a little better by timing press time - leaning on the jack handle longer ?
buy a new truck jack cuz my old one bleeds down a bit...

Thats a good blackpowder boolit - use in my O F Winchester 94 - FFFG blackpowder and a juice box wad over the powder

The point of diminishing returns starts to bite pretty seriously with a round ball gun from 1800fps - other things matter too - fr instance where did that 2800fps 36cal ball go? dont matter how fast...

If that lock eats up flints you might wanna harden the frizzen
A decent condition CVA is capable of that target or better at 100yards
Have fun!!!!

I never wanted to argue with fellers that are having a lot of fun testing stuff - but to me the puck measure always seemed like a pointless excercise - I have some old history in testing procedure...

I dont bother with test weighing at the pressed puck stage (dont believe I would get a useful number the way I go at things) I compare my finished powder to Goex and am right at the same place, 92 -...

mine was only one extra - the cylinder next in line went - just a smudge of lead down the side of the pistol, more noise and more recoil - noticeable enough to stop and figure out something was amiss...

lower fines and dust gets my attention!!!
Part of the push for consistency I have never just re pucked that stuff but kept aside and reprocessed it when I grind the next lot of meal - carefully...
